Cool, I didn't even know that this was possible with PureData! I'm kind of a beginner, so for me, this was useful.

nice! more tutorials will follow soon about how to use webcam to track motion etc.

Just yesterday I was reading about Arduinos and LEDs, and the article claimed you need a resistor that matches the voltage to the LED, otherwise, you can burn the LED. So, you might add that as a disclaimer to the post, if it's true.
I'm a complete electrical n00b though.

well in this case the LED is wired in port 9. wich is a digital port, so no voltage is involved, in this case it can not burn since the value ( pwm 255 ) is the highest possible. only with analog ports ( 5v ) the LED can burn

Great, I'm in the process of deciding whether to use Pd or Processing for a small Arduino project - this tutorial will come in handy, thanks

I used processing also, it's as easy as PD to connect but the features are very difficult. the graphical interface from PD is very nice!
