I tried and and have to say it works but please use ir led which is used for remotes. Other ir led will not have the same wavelength/power output and have really close range like 1cm. I was stuck due to this for days until I usedir led from an old TV remote
This a great start, but not more than that. I would have loved to have had that source code but there are several reasons why I think this is only a good start. * The air conditioner that is controlled is most likely a variable speed air conditioner. It can run at a lower speed to keep the temperature constant. Running at a lower speed makes the system for several reasons more efficient. This arduino controller can only turn the system completely off or set it to run at full power. * I believe having the target temperature set on the remote at 24 degrees while reading the codes is important. Any temperature lower than the temperature we want to regulate (26 degrees) for would suffice. Reading the ir codes while the remote is set to a temperature above 26 degrees would probably not make the resulting sketch work. This is because the remote most likely sends not only an on or off command, but it also sends *all* other settings with that same one command: what the current measured temperature is, what the target temperature is, what the fan speed is, and so forth. Those two points of interest make this project into a nice challenge. You can use the project as is and switch your system completely on and off, or rewrite the code to make full use of the modulating capabilities of your air conditioner.
Thanks for the video! while sending you specified 36khz in the parameter: how to guess this value as the usual one is 38khz? I don't really understand the need for the transistor to control your led? I would appreciate if anyone has an idea.
The best way to switch a charge, such as an LED or another component, is using a transistor, which works like an electronic switch. The reason for this is that the current to saturate the base of a transistor is much lower than the supply current for an LED, which means it does not overload the microcontroller.
Hi sir, I copied and pasted the IR_code_Receive code into the Aduino software but when I tried to verify I got this notification: IRLib2:8:10: fatal error: IRLibRecvPCI.h: No such file or directory #include ^~~~~~~~~~~~~~~~ compilation terminated. exit status 1 IRLibRecvPCI.h: No such file or directory and I couldnt uplod the sketch.

Someone hacked our GitHub and reached out for ransom which we could not afford and hence we lost all our repos. It is now a very tedious task for us to build repos for more than 50 videos again. Hope this makes sense.
Thanks for taking the time and effort in making the video, it was very helpful. One thing I would like to ask is why are we using a transistor? Would having the IR LED plugged to GND and having Arduino control the +VE pin to the LED work? I'm afraid I don't have any transistors lying around =(
Great tutorial, thanks a lot sir, hat's off, it works great for me, even without transistor( short range though). The only problem is, i have a buzzer in my AC unit, so everytime it turns on or off, it makes a sound, I'm looking for a solution to stop it 1- stop the infrared from transmitting (using IDE code) which is the best solution. 2- adding a current reader in the unit, and make it communicate wirelessely. 3- removing the buzzer from the unit ( not keen on this solution. What would u advise me? Thanks again, like and subscribtion from Algeria.
Hi CTech its an awesome video dear, I've implemented the project but the IR is not lighting with Pin3, although it lid with Pin 13 in the Blink sketch! Any suggestion? Thanks...
Well that's because of the advancement of the controller. Each temperature value has its own raw data. therefore we need to assign and have a track of what temperature it is and assign its values.
Dear Sir, nice video. very useful. My question is , can I control 2 different ac with one Uno. What should be the change in program, and which 2 output pins do I have to use?
Actually I have 2 ac in 2 different rooms. I want to ensure that only one is cooling, goes to fan mode, then next room ac to cool, goes to fan mode. This to repeat every 10 minutes, so that my house wiring is not loaded with both ac cooling at the same time... Is it possible to use two IR Transmitter to achive this, then how to tell the specific transmitter to send signal, one after other at gap of 10 minutes.....I hope I am clear
Hello, Thank you for the great video! I was able to read the IR commands and then send them back out okay. But my swamp cooler uses the same commands to turn it on and off. I have tried changing your code with no success, I want the code to be sent out only once, when there is a change. I will assume the swamp cooler is always off when starting. Any ideas would be appreciated. Thanks, Bryan
codes work with my TV (with modifcation ofcourse) but not with the AC. I couldn't find a way. it might be the spectrum of the led. i need a powerful one i guss.
Very helpfull! Thanks so much keep going..!!!😉😉😉 Edit:This uses to much ram from microcontroller can we make something about it or not? (Problem solved...PROGMEM!)
I have been wanting to create a home automation system, I think, your guide would be a nice start to dive into Arduinos and RPi. By the way, can I attach RTC module and turn on the AC and the temperature control only in the evening, off before I wake up? Any pointers? Cheers, from another guy living in a dastardly hot region.
Thank you for the great video, I want to control the air conditioner using nodemcu (esp8266) but it shows me that the code is not compatible, what is the problem?
Hi sir, I had tried the hardware and coding about 3days….. and why my arduino ide keep looping the data temperature = 31 C AC switched ON….. but my aircond is not functioning even when the temperature cold down below 20 C then the aircond also not functioning……why?

Replace loop code with this: if (Serial.read() != -1) { mySender.send(rawDataOn,RAW_DATA_LEN,36); Serial.println(F("Sent signal."));}
The above code will send a signal on demand , it do function I've used the code below
if (temp > 29) {
Serial.println(F("AC Switched On"));
}
else if (temp < 26) {
Serial.println(F("AC Switched Off"));

You have to change the code for each AC brand
