I'm trying to build a circuit that uses multiple multi-color LEDs. I'm wanting this circuit the be able to create all possible colors with one potentiometer. It's really racking my brain (I'm a noob. Also, it doesn't help not knowing anything about ICs). I can easily figure out a 3-4 knob system. But, it just wont work for the application. could anyone suggest anything? I can figure the exact resistance and such that I'll need. I just need a basic layout. Thanks for the help!
