This plant sings!
By connecting a capacitance sensor to a plant one can detect if people are touching it and convert the touch into sound.
Homemade touche shield (Instructable can be found here)
Gameduino (We are going to use it for sound).
A couple of Alligator clips.
Two banana connectors.
Enclosure (I used a wooden box from http://www.containerstore.com/welcome.htm)
Components needed for the touche shield:
Resister: 10k, 1MOmh, 3,3k
Capacitor: 100pf, 10nf
Diode: 1N4148 diode
Coil / inductor: 10mH
