Ok, so there's several ways to power IR boards:
backup battery
12volt circuit breaker block
pwms in digital inputs or analog inputs
so here's my question
if we want to power the board via pwm, which color pwm wires link to the V+ and ground of the ir board.
It seems like it would be black to ground and red to V+, but I don't want to accidentally fry the board because I assumed. Especially because apparently the board is really sensitive to reversed polarity... (has anyone heard of diodes?)
