    Thanks for Frank, we finally got the sound input work readily using radio shack amplifier.

    The basic configuration of the Piezo element is shown here:
    >>code

    Listening to each other -revealing materiality through the vibrational interaction of each component-
    We hope to make the interaction among each component of our output that would require a relatively small scale of input from each. So in parallel with working on sound input (that would be sensing a wider range of presence), the exploration of output based on input of the Piezo element would be good to start with.

    Raw Piezo Element.
    I heard that microphones are made of piezoelectric film. Those piezoelectric sensors consist of a small piezoceramic plate and electrode and are generally used to detect strain or very slight force changes. When bent, they produce varying voltage within a relatively ready-response.

    First, the link of Condenser Microphone, what I tried last semester refers to ITP website ...
    Condenser Microphone

    This semester, I will try this circuit-info by liubo_thanks!
    Hardware
    http://tinkerlog.com/2007/05/20/cheap-sound-sensor-for-avr/

    transistor 2N3904 _really any small NPN transistor with Vebo ~ 5V will work
    2 capacitors 0.1u _1u stands for 0.1 microFarads, the u is a µ symbol electret microphone
