    I'll experiment with this as soon as I can :) thanks for the reply, it will be some time but I will respond back when I need more help (likely) or when I have finally finished.

    Hey buddy I appreciate your information very much, I am going to build this into some things. I am new to arduino (this will be my first thing). I was wondering if I can control this with PWM or somehow integrate a potentiometer in order to dim (even if a 555 dimming circuit is necessary but that can only dim to 5%). Perhaps another arduino so I can control red blue green and white independently (as you have but with a higher degree of control from the potentiometer); then controll the overall brightness of them all with a single controller (allowing me to tune a particular shade of white with pwm, then increase or lower the brightness if I do not exceed any single channel's maximum limits). I really like the fine and easy control that is available with a potentiometer dimming circuit, ...see more »Hey buddy I appreciate your information very much, I am going to build this into some things.

I really like the fine and easy control that is available with a potentiometer dimming circuit, I put em on everything.
