[PD] arduino and digital outputs

[Hans-Christoph Steiner]

The normal Firmata doesn't support the Arduino Mega very well because  
the Mega has a very strange, custom abstraction layer for mapping the  
pins, as compared to the rest of the Arduinos.

Like other people said in this thread, you need to use Paul  
Stoffregen's version of Firmata for Arduino in order for it to work  
well with the Mega.
