The circuits connect 5v out on the Arduino to 12v on the LED Amp input (common anode). This may seem wierd. I'll try to make some sense of it. The R, B, G inputs of the amp are attached to Arduino digital out. Setting a pin to 0 creates a 5v potential to the common anode which will result on a 12v potential on the corresponding output which will light up the LED. In other words, a digital 0 turns the light on. A digital 1 turns it off. Or, when using PWM duty cycles, 255 is off and 0 is on
