Hi,

I'm looking for a circuit which would allow me to continues keep on
fading RGB lamps in and out.
I have 3 lamps(Blue, Green and Red) which all can be controlled with a
voltage between 0 and 10Volt.
The circuit i'm looking for should have blue fading out while green is
fading in, when blue is out, green should be on max voltage, then
green starts to fade out and red starts to fade in. When green is out,
red should be at max Voltage. Then red starts to fade out, and blue
starts to fade in. and so on.

Is there anybody who knows where to find a circuit like this?

Greetings,
Yves

Progam a PIC.
Add an opamp to get 0-10V.
