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.

Not sure if I get you right here, so let's see:
When you use a Wii via Bluetooth into Pd then you don't really need the 
Arduino (unless there's Arduinos with Bluetooth already). Simply make Pd 
output Midi controller values which you assign to level, pan, aux etc. 
in your DAW.
Another nice thing could be to make the Arduino output MIDI directly and 
I think this is not too hard, search the big garbage pile called 
internet. This would be the equivalent to building a midi fader box 
Others might be better at this: If you want to control a DAW's panning 
with the Wii, be advised that it does not detect rotation. Meaning: If 
you hold it like a TV remote control and pan it left and right like a 
compass needle, this does not get detected by the accelerometer.
