So, this project is going to take a little longer than I thought. Last night I tried putting together a circuit board with only ONE RGB (red/green/blue) LED and potentiometers to control the colors, was only able to get the red portion to work with what, upon inspection, looked like incorrect wiring, so I 'corrected' the wiring, and then that same potentiometer smoked out on me (ha, I did get yellow light from it, though just before it burned out!). Now I'm remembering "diode circuits" was when I stopped giving a **** in circuits class. Hmm....
