A universal IR remote control, named after the Flashing Chromis.
This project assumes a Particle Photon or Spark Core with an IR Decoder connected to pin D0. I bought part number CHQ-1838 on Amazon. The IRremote library is hard-coded to output a remote control signal on pin A5. For IR Output, I connected a NPN transistor to A5, and two IR LEDs (in series) with the C-E side of the transistor with 5V (and 50Ω resistor). I used the Photon's 5V power supply to power everything.
Chromis has a very simple interface. When it detects a remote control, it publishes a Particle event:
ir-detected with data representing the button that was detected,
for example: NEC,FF48B7,32. It also outputs this same data string as serial output.
To re-emit this same remote control signal, call the Particle function emit,
with the same button data:
emit ⇢ NEC,FF48B7,32
That's it! Happy remoting!
