So I finally got myself an Arduino, and I have a typical newbie question: anyone know of any good references/tutorials/advice to get up and running using Arduino and Pd?

A couple of weeks ago i also newbishly attached an arduino to my pc. Just downloaded the latest version of arduino, uploaded the standard firmata to the board and the played around with pduino (the standard arduino.pd file contains all kinds of clearly laid-out options), and - to my surprise - got it working after 10 minutes.

Thanks, domien. That's exactly what I was hoping to find.
