Thanks to Alexandre Quessy for tracking down the digital input bug in
the Pduino code. I got it quite wrong with my first attempt. I just
checked in an attempt at a fix, but my laptop is a bit thrashed, so
its not letting me burn a new firmware onto my Arduino.

I'll test it once I get another computer to play with...
