I want to use the ports of multiple Rainbowduino’s to control led’s (but not a led matrix). I understand how to wire this up (led current sinks vs Darlington voltage sources). However, I am finding getting my head around the code tricky…
I am not interested in mtXcontrol or other serial based systems, I just want to be able to simply control all the pwm outputs of multiple rainbowduinos cascaded - Ideally some extrapolation that would mean I would control the outputs like analogWrite() on the Arduino.
Has anybody got a simple sketch to make all the pins blink, or make each output turn on one by one?
