ok - i did a check on the fog machine - the max draw is 24.56 mA - how would i setup to Arduino Uno to accept a pin in and then pin out (et just connect them )?

Lyndon, based on your reply Arduino board with this code your advised. power supply for the Arduino itself Relay ? (not sure how much voltage Arduino supports- but i guessing for the fog machine it would be a NO -closed operation with low voltage? if low voltage i would not need a relay to handle po...

Hi Rappa

this will be a a vehicle - hence the 12 VDC supply. So your suggestion is to run one per colour on the LED R +G+ B - then adjust brightness of each vice a PWM controller to the PicoBuck?

I am guessing the pico buck can support LED in parallel ?
