@AWOL, sorry I didn't include what the debug input looks like, it looks like this:
r = 564 g = 227 b = 218
r = 564 g = 227 b = 215
r = 564 g = 228 b = 217
and goes on and on and on.(this is in the serial monitor window in
the Arduino development environment)
The part where the pot data gets sent through the serial connection seems to be working. The LED doesn't light up at all, even if I turn the knobs.
