Here ya go! The important stuff is inside:
[pd change physical properties] -> [pd sensors] -> [pd guts]
This is Hans' hex interpreter...very needed! All the other stuff is just crazy tweaks to the patch during last minute preps (i.e. very messy and impossible to figure out).
Unfortunately, I could not find my modified firmware code...it is probably on another machine in Kansas City (in Chicago now).
What you can do is take the example that I linked to and then just add the other sensors in a loop. Be sure that there is a short delay between each sensor reading in the operation loop. There is already one after the processes for one sensor, so just duplicate the code chunk as many times as you have sensors.
Good luck!

Hi Kyle!
I'm very interesting on take a look at your patches, especially at your modified wiring code. I have experience sending serial data from Arduino but I don't know how to take this data with comport. Please send me your messy patches!
Thanks a lot!

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.

the arduino object in pd only works with pduino, but it is based on the comport object, and you can use the comport object to send whatever format or information you want. you can also use wireless or midi. this is a paper from last year with a general overview: http://artengine.ca/~catalogue-pd/44-Schebella.pdf saludos! marius.

Hi list!
I'm working on a project with ultrasonic sensors SRF05 (http://www.robot-electronics.co.uk/htm/srf05tech.htm) and Pd to
process
audio. Because of the very short time the sensor needs to work (tens of microseconds), I have discarded to use Pduino (and programing the
sensor
with Pd) and I have programed the sensor with Arduino and sended data
to
Pd with MIDI protocol. Anyway I'm curious about the different solutions that could be for
this
implementation. Would be possible to use the arduino object in Pd to receive value from Arduino (with USB and without using Pduino)
instead
of use MIDI protocol? Or even with comport object? Any suggestion would be welcome!
Saludos!
