@mindthomas thx

[eddiea6987]

are they pulse width modulating or are they all on? Im assuming PWM i dont think arduino can power that many LEDS?

[mindthomas]

@eddiea6987 I'm using 3 PWM channels, one for each color. The common ground pin of every RGB LED is then connected to the ULN2803 chip, where I can enable or disable power sink.

Then I just multiplex all the LEDs, changing the PWM values when I sink power for the specific LED.
