If I understand one method,  a potentiometer is looked up to +v  gnd and 
  one of the Analogue in pins, this then gives a scale from I think 
0-1024 wwhich can then be mapped to the led brightness.

Pulse with modulation from the mood lamp project allows for different 
brightnesses of a tri color LED,  So i am guessing there is a way to 
just control a single pin brightness that way.

May do it
