Hi Onyx,
i would use the built-in I2C bus for connecting multiple arduinos. One of them can do the communication to the host computer.

greetings.  i was wondering, any insight on taking the data from 3 arduinos running firmata and dumping them, using xbee trancievers, to a single comport in in pure data?

my project uses 3 xbee "transmitter" nodes which communicate directly with its own xbee basestation"reciever"  at my computer.  this works but i seek to refine the system to have one basestation xbee that will recieve all of the data from the 3 nodes.  from what i understand of this process, i need to add a tag like "left" in the arduino code" then parse that data on the computer end.  but it seems as if this will break the arduino object. 

my options, i feel, are to try to either add the tag, parse the data in pure data before the arduino object and somehow send the parsed data to 3 instances of the arduino object or to attempt to rewrite the arduino firmaware and the pd recieving abstraction since i dont foresee the hardware configuration changing all that much.  insight? 

cheers,

Onyx
