I am building a new set of musical instruments with embedded rgb lighting for use live. I want to control 6 rgb led strips independantly (via MIDI) and i also want to be able to send dmx data out for use with venues where that is applicable.
the way i started prototyping it (with an arduino mega 2560) i use 3 PWM pins per led strip. but then i would need 18 pwm pins, 2 arduino megas.
Anybody care to share some thoughts on better solutions to this. preferably using a good old atmega 328, though I also have a teensy lying around somewhere.
I remembered seeing soe videos a while back of people controlling several rgb strips with one set of 3 pwm pins but i can't seem to find them now.
