Hi,
I'm trying to build a board for a little RGB lighting controller, specifically a 'Big Clive' one. However I think this works by supplying constant +V power to the LEDs and pulling their negative leads low via N channel mosfets to turn them on. However, I need to be able to source current to the LED's positive legs as I'm using some all-in-one LEDs which are common ground.
Can anyone tell me how I would change this around from the circuit he's posted on his site, and what changes would be needed to the circuit layout and parts list. I'm not sure quite if the controller pulls the output pins on it low to turn on the mosfets or if it puts them high - I haven't quite worked that out.
So if someone could explain to me how to turn it from pulling negative to turn on to providing positive to turn on, that would be great.
Thanks
