SamClayton / BasicTest_-_Sam_mod_2_stay_white.ino
Created April 29, 2015 21:02
basic WS2811 string test pattern that runs through some color combos, then continuously sends a full-white (RGB 0xFFFFFF) signal to the chain every second. this is to allow for breaking the data or power connections somewhere on the chain during test pattern run time
