I have long wanted to have a small remote control for controlling various household appliances... And finally, hands got around, and there was enough free time to create your own universal remote control! I tried to make it smaller, more comfortable, more beautiful ... in general, look what happened!
1 How it works.
Most of the universal remotes that I have on sale work on the principle of preset IR commands. That is, a large database of protocols of various consoles is recorded in the memory of the console and its code is driven in to select the desired one (a book with codes is attached to the console). The advantage of this approach is that you need to dial one code to configure all the keys on the remote control. The disadvantage is obvious - the remote control will only be able to work with those household appliances from which it has commands recorded in memory (for the case if the necessary model of household appliances was not found in the booklet, the manufacturer of the universal remote control recommends trying the closest ones that are suitable for the model or generally everything in a row) ...
I took a different path. In order not to create a huge database of commands for various consoles, I decided to record IR commands from the original remote control into the microcontroller's memory and then play them back (a kind of recorder for IR commands). It makes no difference to the learned remote control what protocol the original remote control uses, it does not matter what format and length of the IR command, it records all the information transmitted by the original remote control in raw (RAW) form and reproduces it in the same way.
Of course, there are limitations, and some remotes cannot be studied for objective reasons:
- the trained remote control perceives IR-messages TSOP operating at a frequency of 36 or 38 kHz (the vast majority of remotes operate in this range) - this does not make it possible to perceive a message from a remote control that operates on a carrier that is very different from the TSOP carrier (for example, 30 or 56 kHz );
- protocols of consoles with feedback(for example, like air conditioners), for obvious reasons, cannot be reproduced;
- non-standard protocols that have a specific structure of the IR command (for example, the command is split into several messages).
2 Console design.
The learning console is a small box with touch keys. The whole structure is powered by a three-volt 2032 battery. There are 9 touch keys on the body, 6 of them are used to control equipment (remote control keys) and the remaining 3 are used to select a set of commands (respectively, you can record and play up to 3 sets of commands, 6 commands each). There is also a tact button for switching between operating modes. Structurally, the console consists of two boards:
- first - control board -;
- the second is the sensor board (you will find its description below in the text).
Both boards are connected to each other using connectors, forming a one-piece compact design.
2 Diagram of the remote control (universal remote control shield).
Universal remote control diagram
The figure shows a diagram of the universal board together with the shield of the learning console. Different microcontrollers from the ATmega48 / 88/168 series can be installed on the baseboard. The components of the circuit are not critical in terms of their values and allow for little variation. Probably, you will have to choose a damping resistor for the IR LED. The lower the value of this resistor, the stronger the signal from the remote control, but the faster the battery will run out.
Initially, the remote was planned to be powered by three AAA size batteries, which would be located in the battery compartment attached to the bottom of the remote, but field tests showed that a small 2032 battery of 3 volts is sufficient for satisfactory operation. Of course, the power of the IR signal decreases somewhat, but remains within the aisles of comfortable work. In this regard, the printed circuit board of the sensors was slightly changed, where a place was added for attaching the 2032 battery.
But it should be borne in mind that not all TSOPs are capable of operating at a supply voltage of 3V. If your TSOP does not work from 3 volts, or you need a powerful IR signal that can work at long distances, reflecting from walls and ceilings, then attach the battery compartment for three AAA batteries to the bottom of the remote (a closed battery compartment will not even spoil the appearance ) and you get a powerful remote control and long-lasting work.
3 Printed circuit board
How to Assemble the Control Board - Making the printed circuit board of the learning console shield can be a bit tricky due to the relatively thin tracks and large polygons of the touch pads. After etching and tinning the board, it is imperative to view / ring all the tracks for breaks and short circuits among themselves.
Here I leave the layout of the base board and the board of the console shield together with the side walls in one place (for the convenience of making all the boards in one go).
Remote control PCB drawing
4 Assembly of the structure
After you are convinced of the integrity of the shield tracks, we solder the components. There is nothing special to solder, but there are some nuances:
- indicator SMD LEDs (there are two of them in parallel) must be soldered sideways, so that their glow can be seen through the board.
Initially, it was thought that these LEDs should be directed inside the case and illuminate the entire plane of the sensors with reflected light, but to save the battery, we had to reduce the LED current and the backlight became difficult to see.
By the way, LEDs don't have to be SMD. Can be drilled into convenient place board a hole and install a regular LED there, pulling power to it with wires.
- Another problematic element for installation is a piezoelectric emitter. The dimensions of the piezoelectric emitter do not allow it to be installed in any particular place (it simply does not fit), so you will have to be creative in its installation. For example, I cut a standard piezo plate with scissors to a convenient size and soldered the plate to the bottom of the remote control.
If nothing works with the piezoelectric emitter, you can install an LED instead, not forgetting to put a quenching resistor (300 - 1000 Ohm) in series with it.
- The sensor board has three side walls, soldered perpendicularly (the fourth end wall is soldered to the universal board). When connecting the universal board and the sensor board, the side panels must not rub or wedge between each other. To do this, you need to adjust the boards to each other - you will have to work with a file :).
5 Microcontroller firmware
The base board is stitched through the standard ISP-6 programming connector (it is in the middle on the side of the base board).
- Firmware ATmega88 universal remote control
- Fuses of the ATmega88 universal remote control
Let me remind you: For Algorithm Builder and UniProf, checkboxes are set as in the picture.
For PonyProg, AVR Studio, SinaProg, checkboxes are put inversely.
How to program microcontrollers read in
After the microcontroller is flashed and the operation of the remote control is checked, we start working on the appearance of our device. Since outwardly the path is a rectangular smooth box folded from printed circuit boards, decorating will not be difficult. You can give the console a "presentation" different ways, for example, paint with paint from a spray can and then apply a drawing of the keys or print a picture of the front panel on paper and glue, etc.
I chose the method described in. I printed the drawings of the front and rear panels of the remote control using a color laser printer on self-adhesive paper, glued the drawings to the remote control and covered it with a protective layer on top (glued a wide adhesive tape on top).
It turns out quite interesting, especially since the design of the keys can be chosen in the context of your interests or the intended household appliances for which the remote control is intended.
Here are some general key designs.
Remote Control Touch Panel (DOC) Drawings
6 Learning console operation
The remote control is ready, now I will tell you how to work with it.
To get started with the operation of the remote control - the controls:
- hardware (contact) key Set serves for various purposes, but the main ones are the transition between operating modes, lulling the remote control and bringing it out of sleep;
- indicator Led(in the picture it is a little out of place, but everything flows, everything changes ...) serves to indicate various operating modes + sensor illumination;
- touch keys change programs and level changes have autorepeat (functions: volume, channel switching, brightness, timbre, ...);
- touch keys Power and Mute do not have autorepeat (needed for single actions: turn on-off, open-close, ...);
- sensors for selecting a group of commands make active one of three possible sets (6 each) of command-sensors (for example: 1-TV, 2-amplifier, 3-light);
- there is still a piezo emitter Buzzer (inside the case), it reads keystrokes and performs a number of other actions.
Now the algorithm of work itself:
- When you turn on the remote control for the first time (power up), it will start the procedure automatic tuning sensors. Before tuning, with short pauses, two long and one short beeps will sound. The sensors will automatically adjust immediately after a short beep. At the time of automatic tuning, the touch pads must be free. - Then the console switches to the playback mode of commands from the first group of commands. A long beep will sound, followed immediately by a short one (the first set of commands). Will light up Led... If you press the sensors now select a group of teams Then a long piiik will sound and, immediately after it, depending on the group number, the number of short ones. Command group switches work the same in all modes.
- When pressed in play mode command sensors, a short sound signal(peak) and an IR command is issued.
- If the remote control is not touched for a while, it will go into sleep mode by itself. In sleep mode, you can enter the remote control by forcibly pressing briefly Set... Short press on Set in sleep mode, the remote control wakes up and it beeps the number of the active group of commands (so as not to poke your finger again 😉).
- If you hold down for a long time in playback mode Set, the remote control will enter the learning mode by emitting two short beeps, and Led flashes continuously. When you press any sensor, the LED will go out, a long signal will sound and the remote control will wait for an IR-message from the original remote control. If the package is received, a long beep will sound, the remote will remember the command and return to the learning mode. If there is no sending for a long time, a short signal will sound and the remote control will switch to the learning mode on its own. Also, waiting for an IR message can be canceled by short pressing Set... In the standby mode of the IR-send of the original remote control, you can select other sensors or groups. Actions sensor selectors similar to playback mode.
- You can return back to playback mode by holding down Set(two short beeps will follow) or, after some time of inactivity, the remote control will go into playback mode by itself.
7 Problem solving. Debugging the design.
The sensors of the device are the thinnest and most sensitive element of the design. They need careful manufacturing (not washed off flux or dirt on the board can significantly impair or even make the operation of the sensors impossible) and fine tuning. Measures were taken in the program to make the operation of the sensors more reliable:
- at startup, the program checks the sensor lines for short circuit absence. In the case when there is a supply voltage on the sensors (the worst option, which can lead to "burnout" of the microcontroller ports), the program will stop its execution and give an error signal;
- at startup, the program automatically adjusts the sensitivity for each sensor separately;
- with successful initialization of the sensor ports and the first setting of the sensitivity of the sensors triggering, the program will write the sensitivity levels for all sensor pads in the EEPROM from the first address (zero address - general sensitivity) in the following order:
EEPROM:
&01
Up
&02
Down
&03
Plus
&04
Minus
&05
Power
&06
Mute
&07
Sel1
&08
Sel2
&09
Sel3
By reading the sensitivity table from the EEPROM using the programmer, you can indirectly evaluate the quality of the sensors and diagnose problems with their operation.
Namely:
- Normal sensitivity lies within the values: 20-50
... These values are not absolute, since many factors affect the sensitivity of the sensors:
- Values close to 0
they say that the touch pad has leaks on the "+ power supply" (there can be no short circuit, since the program in this case simply will not start working (an error signal will be continuously issued). tracks of the wrong size (less than 1 MΩ) pull-up resistors of the sensors, poorly etched gaps between the tracks on the board.
- Values close to 255
talk about leaks to "ground" (up to a short circuit), or an open circuit in the sensor pad - the leg of the microcontroller, or an open circuit of the pull-up resistor of the sensor (the one that is 1 MΩ). The reasons for leaks to the ground can be: poorly cleaned board; "Snot" between the tracks; poorly etched gaps between the tracks on the board.
- The values of the sensitivities of the sensors should be approximately the same. Too large scatter of values, although it is not an unambiguous indicator of their incorrect operation (sensors are processed and adjusted individually), but indicates that there are some problems.
In case of unreliable operation of the sensors, at the zero EEPROM address, using the programmer, you can manually set the overall sensitivity of all sensors. In this case, a zero value corresponds to the maximum sensitivity, 19 - the minimum, values greater than 19 will set the default sensitivity - 5.
EEPROM:
&00
Sensitivity
When flashing the remote control, the EEPROM is cleared and all cells (including zero) receive values of 255, which automatically sets the nominal sensitivity.
8 Shield forArduino
Since the remote control is assembled on a microcontroller used in boards such as Arduino, Freeduino and the like, it is logical to make a universal remote control shield for them as well. On this moment I have not yet bred such a shield (I did not get my hands on it), but if you manage to do it faster (and test it for performance) - send materials and I will gladly post them in this part of the article. Here's the basic Arduino shield board in Sprint Layout to help you:
- Arduino shield blank (Sprint Layout)
Universal remotes are different in functions, price categories, purpose and country of origin. Usually Universal remote designed to control all appliances in the house from one remote control. We have a good range of universal remotes for almost every taste. So, there are generalists:
- Programmable remotes- these are consoles in which the base of codes for managing a large number of manufacturers is initially laid. Such a remote control always comes with an instruction manual, which lists the types of equipment, manufacturers, and sometimes brands of specific native remotes, instead of which this universal remote is ready to work. In order for this remote control to control your equipment, you need to find the required manufacturer in the code table and enter the code into the remote control. Some programmable remotes are only for one type of equipment, for example, only for DVD.
- Learning consoles- these are consoles that provide for the presence of a native console. The remote control is placed opposite the remote control and learns step by step, i.e. the station wagon takes over all the functions of the original, it becomes completely identical in functions. The learning option is very useful in cases where the remote control needs to be tuned for a rare type of equipment (for example, an Akira home theater) and it is simply impossible to find the code in the code table.
- Teachable + programmable- these are the most versatile remotes, tk. combine the two previous types.
Some remotes, in addition to the "main" purpose, have additional features... Here is some of them:
- Support for Macros. A macro is the execution of a whole list of functions by pressing just one button. In practice, it looks like this: For example, you want to prepare your home theater for watching a DVD movie. To do this, you turn on the TV, set it to AV mode, then turn on the DVD, then the home theater receiver, then press Play, etc. Now, using a macro command, you can assign all these functions to just one button.
- Operation of the remote control on a radio signal implies that the remote control operates both on IR and on a radio signal, which allows you to control all equipment from anywhere in your home (this requires an additional device - the Power Mid pyramid).
- Touch control- there are fully touch-sensitive consoles, and there are consoles, where half of the remote control are ordinary buttons, and the other half is a touchscreen display.
- PC support. In some programmable remotes, you can update the code base via a PC and a cord, in Hi-End class consoles, you can program the remote directly through the computer.
Attention! This section presents universal consoles from those manufacturers who mainly deal only with universal consoles. You can find "branded" station wagons in the corresponding sections by manufacturer names, for example,
If you lose your TV remote control, you don't have to worry about it. There are always universal remotes on sale that, after a fairly simple procedure, can easily replace the original model. The process of connecting to a TV will take no more than 10-15 seconds. It is only important to know how to set up a universal remote control.
Device device
Design of the universal remote control remote control no different from the original models. Both types of devices have buttons for selecting channels, adjusting the sound, setting the timer and others.
Typically, both devices run on the same AA or AAA batteries. If you use one remote control for a large number of devices, then the batteries will have to be changed more often than in a conventional model.
Some features of the internal device may determine which devices can be controlled and how to set up the universal remote control. Gal LM p001, for example, has the ability to quickly connect to TV and SAT. Some other models are not equipped with this function.
Comparison of the original remote control with the universal
There is no external difference between the two types of control devices. They differ only in the set of functions.
The first and foremost difference is that universal remotes can be connected to a large number of devices and devices. You can use them at the same time. For example, using one universal remote control, you can turn on a TV, air conditioner, music Center and any other electrical unit that allows remote control. Also, the remote control will allow you to control home theater functions, satellite dish and cable TV.
In addition, the cost of the universal remote control is lower than the original model, and the lifespan is generally longer.
For owners of old TV models, this universal device will be a salvation in case the original controller is lost. The original remote controls for the models of previous years are simply not produced.
Are they really versatile
Any remote control can be used with different models of TVs, players and air conditioners. There are, of course, exceptions. For example, what if you can't set up your universal remote? How can you check if it fits a given device model? First you need to see the list of compatible models in the instructions for the remote control itself. If there are no instructions regarding this, and the connection cannot be established, the problem may be both in the remote control and in the TV.
The versatility of remote controls is determined by the fact that, unlike original devices, which can be configured to work with only one device, they can simultaneously work with different devices from various manufacturers. At the same time, they do not have to be reconfigured every time.
How to set up a universal remote
To establish a connection between your TV or other device and the universal remote control, follow these steps:
- Turn on the remote control and point it towards the device.
- Simultaneously press the OK or SET button (depending on the model of the remote control) and hold it for 3-5 seconds.
- Enter the code that matches your device model.
- Then press the TV button to confirm the connection.
If for some reason the remote control does not connect to the TV, you need to do these steps again. An incorrect device code may have been entered.
There is another way to set up the Huayu universal remote control. To connect such a device, you can use autosearch:
- Turn on the device to be configured.
- Press the SET button and then POWER.
- Release the buttons at the same time.
- Press the POWER button again and release.
- Check if the volume indication appears on the screen.
- Press the SET button twice in a row.
Not all universal remote control models support the auto search function. It is also possible that the auto search function is not supported by the TV model itself. Therefore, for some cases there is only one way to set up the LM P001 universal remote control - manual.
Some brands differ in function quick search... To connect in this way, you need to perform the following sequence of actions:
- Turn on the device you want to connect to.
- Press and hold the TV button for a while.
- Release the button when the power indicator is on.
- Press and hold the MUTE button.
- When the connection is made, release the button.
- It is easy to check the operation of the remote control - just change the channel or adjust the sound.
If none of the methods came up and the code specified in the instructions did not work, you can use the last method - sequential iteration of the code manually.
How to determine the TV code
Each model of the device has its own universal code that allows you to connect a remote control to it. It comes in three, four and five characters.
For example, to find out how to set up a universal remote control for Samsung, you need to look at the code information in the instructions for your TV or air conditioner.
It is important to remember that you need to enter the code of the connected device, and not the universal remote control.
Smartphones with universal remote function
Some newer brands of phones allow them to be used as a universal remote control. As a rule, they can only be connected to TVs with the SMART TV function.
To set up a universal remote control on a smartphone, you need to download a special application and follow the installation instructions that will light up on the screen. With the help of the program, it will be possible to interact not only with the TV, but also with other devices that allow the remote control function.
This useful feature is available for a limited number of smartphone and TV models. To use the phone as a remote control, both devices must have a Wi-Fi module, infrared port or Bluetooth connectivity.
How to set up a universal remote? All universal remotes for TVs, players, air conditioners, barriers and gates work according to the same principle. Each button of such a remote control, when pressed, can generate a code of a certain sequence of IR pulses of the remote control, one code out of many.
The codes for the remote controls are stored in non-volatile memory. The question of how to set up a universal remote control comes down to choosing from a variety of codes one that corresponds specifically to your TV, barrier or other device.

First of all, it should be noted that universal remote control cannot become a full-fledged replacement for the regular one. There are several reasons for this conclusion:
- The need to configure a universal remote control- setting the code suitable for your hardware
- Resetting the remote when changing the batteries- the need to periodically replace the batteries of the universal remote control will lead to the need to re-configure it
- Not matching pictograms- the graphic designation of the buttons of the universal remote control does not always coincide with its functions.
- Lack of a number of features- adjusting the volume, changing channels and turning off the TV are the most frequently used buttons on the remote. However, the performance of these buttons does not guarantee the possibility of using absolutely all the functions provided on the standard device.
- Inability to connect- yes, unfortunately the universal remote control may not fit your receiver, player or TV at all.
Therefore, if the remote control fails, you should not rush to purchase a universal remote control. Affordable Chinese counterparts, of course, are inferior to branded remotes in terms of durability, but the disadvantages listed above are absent in them.
However, it is often impossible to purchase a similar remote control. In this case, a universal remote control can help out.
How to set up a universal remote control
How to set up a universal remote for a TV? How to set up a universal remote control from an air conditioner, gate or other equipment? This can be done in one of two ways:
- Manual code entry- each brand of equipment has its own encryption code for the buttons of the universal remote control. It is enough to enter a certain numerical sequence for the universal remote control to be tuned to one or another brand of equipment.
- Automatic code search- in this case, the universal remote control slowly goes over the various encodings of the equipment. If the user detects an impact, for example, turning off the TV, it is necessary to press a certain button, disabling the automatic enumeration of codes. The last code will be saved in the memory of the universal remote control and will be used for control.

How to choose a learning remote control?
There is a huge variety of assortment, therefore the question of choosing a remote control often becomes difficult. Purchase a remote control according to the one you like appearance- not worth it.
"Universal remote control" includes a fairly large number of completely different remote controls in terms of functionality. Therefore, before making a choice, you should decide - for what purpose you need a remote control in general.
Often a person is guided by the idea: if universal remotes are offered, then they should be suitable in general for everything that is in the house. It's a delusion.
Universal remotes are subject to customization. But this does not apply to all equipment and not all functions. So, for example, the universal remote control may not support the “menu” and “program settings” function for the TV, and without this, the control will be incomplete.
That's why, the best solution is a selection of a model of universal remotes with a learning function. Teachable TV Remote - modern solution for a modern home.
What kind of remotes are there?
1.With presets. The manufacturer reads signals from native consoles into its base, then numbers these readings for certain codes. The user enters a code that corresponds to his brand into the remote control and controls the equipment first with one code, and then with another, etc. There may be an option when the code is not spelled out instead of a specific "dear" remote control, but a list of codes for a specific brand is indicated.
2. Remote control with configuration via computer. The setting is carried out using a special software... The bottom line is that the manufacturer's server contains a large number of settings intended for various devices... You can select these devices in the program and click the "update remote control" button. Then the “smart” universal remote control will fill in all the information you need. Moreover, you can check compatibility: this is done on the manufacturer's website. For example, Logitech is one of the leaders with a fairly extensive base of settings for a wide variety of equipment.
3. Learning remote control. At the same time, for each button of the new remote control, there is a possibility of the signal learning function from any button of the "native remote control". The universal learner's console is able to perceive, memorize, and then reproduce signals from the "native" consoles.
How is the learning process going?
It is necessary to place the remotes opposite each other at a distance of about 5-10 cm. At the same time, depending on how many devices are provided in the "universal" and how many buttons on each layout, add up the total number of buttons capable of learning.
Attention: if you are the owner of rare brands of devices with initially "non-standard IR signals according to the protocol", then not every universal remote control will be able to learn from the "native" remote control. Therefore, you need to choose a remote control with a sufficiently wide range of supported signals.
The remotes are capable of combining all kinds of configuration options: programmable + trainees or configurable via PC + trainees.
When determined the best option regarding customization, then a choice is made according to the number of supported devices, design, color scheme, weight, cost and various additional options, such as the function of macros.
Depending on how many categories of equipment the universal remote control can manage, it has a name. For example, "3-in-l" is the ability to replace three remotes at once. It can be video + TV + satellite receiver. If the name is "6-in-l", then such a remote control "controls" already six devices.
How to use the universal remote control?
It's simple. You need to select a program number and adjust the volume. When it becomes necessary to turn on, for example, video, then you will have to use a special switch or button. Thomson equips its devices with switches, and Philips developers have provided a special button that sequentially cycles through the types of devices. A special indicator lights up opposite the icon the user needs at the moment. It also blinks when a button is pressed, demonstrating the operation of the remote and sending commands. Interestingly, such models often have both two and three button fields. Each of the fields is directly related to a separate category of technology.
