I've recently been given a bunch of flux-type RGB LEDs which I planed
to use in a small lighting project controlled with my OOPIC-R via PWM.
The problem is that the LED's are common anode, and I was expecting
common cathode. Is there any way to make use of these LEDs without
having to build any circuitry external to the oopic-r? I'm only
planning on running four of these RGB leds, (4x3 colours, 12 LEDs in
total) not a very big array. The oopic-r would (as you can probably
guess) simply fade between R, G and B over time. I'm pretty much a
beginning with the electronics side of engineering, but from reading
round I've found that to control common anode LED arrays (seven segment
displays or RGB LEds) you have to sink the current coming from the
cathodes. Is the OOPIC-R able to do this through its signal pins?
cheers
