[PD] GPIO into RPi

[Alexandre Saunier]

Hey Julian,

I'm writing another one right now (still on my github), it should be done quickly. It's based on some adafruit's tutorial but adapted to use a Maxbotix ultrasonic sensor.
Like I told you I use python and OSC but I'd be glad to hear about other experiments.

Cheers,
Alex
