I was able to download the firmware into arduino, and worked with the popular example of connection to pd found in the web. Now i am interested in knowing what .pde file should I program for the piezo device to be recognized. Finding out how I should connect the piezo to the arduino, and rewireing this to Pd.

Actually the rotation is not detected but can be calculated from the 3
accelerometers this is explained on the helpfile of the [wiimote]


It works very well for me.
