Hey Fernando,
The protocol is documented here:
http://firmata.org/wiki/Protocol
A digital message will give you a 'port', which is 8 pins. The
digital command is 0x90, and that's combined with the port#, so 0x90
means digital port 0, 0x91 means digitial port 1, etc. all the way to
0x9f which is port 15. Pins 24-37 are on port 3, so you want to look
for messages starting with 0x93.
