Simple Serial IR-Arduino Bridge

The main goal of this project is to provide a serial connection betwen an Arduino (using now an Arduino Nano) and a Windows (or any .Net Core compatible) system.

Arduino Sketch

You can find the sketch here. In order to compile it you need the Arduino-IRremote library.

Arduino-IRremote: https://github.com/z3t0/Arduino-IRremote or also via Arduino IDE Library Manager.

Command Line Application

To run the application simply open a terminal an run the SerialIR.Console.exe with the required -c and -p parameters.

> .\SerialIR.Console.exe --help
SerialIR.Console 1.0.0.0
Copyright c  2020

  -p, --port       COM port with Arduino.

  -l, --list       (Default: false) List current COM ports.

  -c, --config     Configuration/Mapping file.

  -v, --verbose    (Default: false) Prints all messages to standard output.

  --help           Display this help screen.

  --version        Display version information.

For the configuration/mapping file here is an example for the Apple Silver Remote:

{
	"name": "Multimedia",
	"remote": "Apple Remote Silver",
	"keys": {
		"77E150A4": "VOLUME_UP",
		"77E130A4": 174,
		"77E1A0A4": "MEDIA_PLAY_PAUSE",
		"77E160A4": "MEDIA_NEXT_TRACK",
		"77E190A4": "MEDIA_PREV_TRACK"
	}
}

The HEX value in the keys array is the code registered by the Arduino IR receiver. You can run SerialIR.exe -p <COMPORT> -v to just read the codes.

The value in the keys array is the computer key to be pressed, see VirtualKeyCode.cs for the complete list of keycodes. You can either put the value (174) or the name of the value (VOLUME_DOWN).

You can add as much keys as you want, and use (theorically) whatever remote you have as long as it is IR.
