ToniA/Raw-IR-decoder-for-Arduino: Take raw IR signal from a remote receiver and print out pulse lengths
Decodes long IR codes, for example from air conditioner / heat pump devices.
Shows the timings, the symbols, and also the decoded signal for certain air conditioners.
Required hardware:
- Arduino (any compatible will do, but Arduino Uno or Nano is easiest for prototyping)
- Infrared receiver, for example VS1838 will do fine, see also https://arduino-info.wikispaces.com/IR-RemoteControl
- Breadboard, wiring
- IR remote control from the aircon/heatpump you plan to decode
Defines for the different brands were introduced to limit the memory footage on a Arduino UNO. Uncomment, in the beginning of the sketch, the define for your remote brand. You will get a compiler error if you forget to uncomment!

- Open the sketch from subdirectory 'rawirdecode' in Arduino IDE and build
- platformio.ini contains build definitions for Arduino Mega, ESP32 (both tested on M5STACK ATOM LITE) and ESP8266 (tested on nodemcu)
- On Mega, connect the receiver data pin to GPIO 2
- On ESP32, connect the receiver data pin to GPIO 25
- On ESP8266, connect the receiver data pin to GPIO 5
- Connect an IR receiver into the Arduino
- Start the sketch, and enter 1, 2, 3, 4 or 5 into the 'Serial Monitor', to select which timings to use
- Try out the alternatives until you get sensible output
- The signal should always start with 'Hh', and within the signal there should only be a couple of 'Hh' pairs (if any)
- 'H' and 'h' should be there only in pairs 'Hh'
- 'H' stands for 'header mark' and 'h' for 'header space'
- Point your IR remote to the IR receiver and send the code
- If the symbols are known, then the decoder shows its meaning on the serial monitor
- If the symbols are unknown, then you can help by writing a decoder for the unknown remote
-> Mode '9' can be used to decode known signals, in that case you can send the symbols from the terminal, like entering this:
Hh001101011010111100000111001001010100000000000111000000001111111011010100000001000111001011
