Overview
OSC message generation
We used cooked spaghetti to send Serial messages to processing via Arduino using the analogue pin and a voltage divider circuit with the spaghetti acting as a variable resistor. (More documentation of this here) Processing then sent on these values as OSC messages to Max MSP and Unity.
Visual Part
Computer 2 splits the incoming OSC-messages to be read by unity on the same machine and sent to computer 3. This is easily done in MAX:
Unity gets the code with a script like this (google might help):
and makes the object move, in this case spin, depending on the OCS signal
Sound Part
Max patches for generating noise:
