Currently I am working on a project that will use an Arduino Pro Mini and needs to control 18 LED's independently with PWM. The Arduino can only do 6 independently...so what part would I need to buy to expand the number of outputs? I know shift registers can only do on/off functions, not fading, so …

Multiplexing & PWM

Check out the ShiftPWM library, or use a TLC5940.
