Variable voltage output from a Pic?

[BobK]

Hello,

From the picture you provided and the description of your project it looks like each color has it's own pin plus a common for all 3 colors. Why then would you need PWM? It would seem like you only need an "ON" or "OFF" for each color which then is 1 pin per color which would then mean 5 LEDs per PIC.

Let me know if I'm off base here but after reading the above posts that's the way I interpret what you want to do.

Bob,

that way you would only be able to produce 7 different colors.
If you want the full spectrum you have to control the intensity of every base color individually.
