Hello, I am new to arduino. I plan to connect a piezo device which can send a signal to b recognized by pd as a bang. 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 what you are trying to do, but could connecting the piezo to the computer's soundcard, and detecting a volume peak within pd, do the same thing?
