SoftPWM Library
I needed a library to produce a pulse-width modulated signal for an arbitrary pin on a Wiring board, so I wrote this. It was to control a number of LEDs, giving them shades of brightness, versus just ON or OFF using digitalWrite(). You would use analogWrite(), but that is limited to a very few pins.
