RGB Mood Light Help

FallenDemon:
What do I attach to Pin 0? I uploaded the code to my arduino and all I see is the red and green LED fading dimmer and then brighter. Please help.

get a potentiometer of about 10K to 50K. Connect one end to +5V. Connect the other end to Ground. Connect the wiper to A0. The knob controls the color.
