Released 2012-03-18 — tested with pd 0.41, pd 0.42, pd 0.43
fully supports Firmata 2.1
There are no experimental releases available at the moment.
This is a [arduino] object for Pd and a matching firmware. The firmware could be used from any program, really. The idea is that everything is controlled from the host program rather than having to update the firmware. For complete documentation on the protocol, see http://firmata.org, for the Arduino library, see: http://arduino.cc/en/Reference/Firmata
