I'd like to connect an IR receiver to my Rainbowduino. Are there any free digital I/O ports I can use?
There are plated through-holes for A0-A7 and D2 and D3. The IR receiver code I want to use (IRremote.h) uses interrupts - will that stop me from using D2 and D3 for the IR data input?
Can I use the TXD or RXD pins on the sides of the board, meant for connecting Rainbowduinos together? (Are they connected to D1 and D0 as on a standard Arduino?)
Thanks,
Robert
