So lately I've been trying to get piezos hooked up to my Arduino to output midi messages to trigger drums. Luckily, there's the firmata protocol for the arduino (http://www.arduino.cc/playground/Interfacing/Firmata) that works with processing (http://www.arduino.cc/playground/Interfacing/Processing) to make life much easier.

However, that led to me wanting to filter my arduino's analog inputs to prevent double hits, etc... so I made this dandy arduino input monitoring script so I could work out the kinks in my project

This is really the first time I've used java/processing/arduino (lots of firsts!) so please point out any bad coding habits/etc... that you notice =] any suggestions or feature requests will also be looked at, but no guarantees - hopefully i'll add things like:

*multiple sensor graph overlays
*a real-time filtering/mapping section
*peak analysis / integration to determine "velocity" (to use a midi term)
*a midi output mapping system
