​

This sketch will send one binary byte from P5 to arduino

See arduino code in bottom, have LED connected to pin 3

​

move mouseX to dim LED*/

var serial; // variable to hold an instance of the serialport library

var fromSerial = 0; //variable to hold the data

  serial.list(); // list the serial ports
