[PD] Ultrasonic sensors & PD

[Kyle Klipowicz]

I have successfully used 6 Parallax ultrasonic sensors with Arduino
and Pd to generate audio and video material twice.

There is a very nice Wiring project for an ultrasonic sensor that can
be hacked to add additional sensors. It is located here
(http://www.arduino.cc/en/Tutorial/UltrasoundSensor).

The code works over comport as discussed, and there is a handy bit of
trickery in the Pduino that Hans crafted that sorts out the raw hex
values into something useful for manipulation.

You just need to make sure that there is a brief delay as the
microcontroller communicates between each sensor. This causes a slight
delay as the Arduino loops through the code, but for my purposes the
delay was negligible.

If you would like to see any of my (messy) patches or my modified
wiring code, please ask and I can shoot them to you.
