[PD] Ultrasonic sensors & PD

[Hans-Christoph Steiner]

I am working on making that handy bit of trickery into an Arduino  
library.  It should be usable now for an ultrasonic sensors.  Right  
now, you can send data using the Firmata library in Arduino, then  
it'll work with the [arduino] object in Pd, or any  arduino object in  
other languages.  You can seen an example here:

http://pure-data.svn.sourceforge.net/svnroot/pure-data/trunk/ 
externals/hardware/arduino/Pd_firmware/Pd_firmware.pde

You'll want Firmata.sendAnalog().  Just a warning this is alpha, it  
works fine, but the API might change.
