I have a problem with the physicalpixel example sketch, mainly that I don't seem to be able to make it work.
I have a Duemilanove board with 328. When I type 'H' or 'L' from the serial monitor, nothing happens.
I have tested that I can turn the led on, I have tested that I can read serial produced from the arduino, but nothing I have tried seems to make the led turn on via serial.
