/*  11.3. Arduino UART receive/transmit a packet and decode with an oscilloscope demo sketch 
 * 
 * Use this sketch to experiment with the decoding of a multi-byte packet
 * that is received and transmitted by an Arduino on an oscilloscope.
 * 
 * Use in tandem with the matching Processing sketch
 * 
 * Connect CH1 of the oscilloscope to pin 0 of the Arduino.
 * Connect CH2 of the oscilloscope to pin 1 of the Arduino.
 * 
 * 
 * This sketch was written for Oscilloscopes for Busy People by Peter Dalmaris.
