Oh dear... Yeah, the power from my PSU is clean. It had better be too... Spent a small fortune on it!
If I can only power the chip with 5v, how on earth could I use it to control 12v LEDs? Is there a way I can hook those little guys up to a different power source? IE 5v Red wire to power atmega and other bits, then yellow 12v to power the LEDs?
Thanks for the advice!
