Mechanism

The wallSound circuit is built based on Paul Badger’s CapSence library for Arduino. The library turns the Arduino pins into capacitive sensors, which measures body resistance and read the changed output frequency. The circuit includes 1 megohm resistor between the send pin and the received pin which is the sensor pin. A wire is connected to the copper that absolute touch activates. The delay between the send pin changing and the received pin changing is determined by the resistor and body capacitance. This structure was duplicated in a way that each circuit reads one copper stripe body. The Arduino communicates with Processing. Using Ess sound library, patches of mp3 are being played and paused in correspondence to the state of the circuits. The Arduino communicates with Processing.
