 * Serial Read and MaxMSP
 * by BARRAGAN http://barraganstudio.com
 * 
 * Demonstrates how to read data from the serial port.
 * If the data received is an 'H', the light turns ON,
 * if it is an 'L', the light turns OFF.
 * The MaxMSP patch is included as comented text below.
 * Copy the text of the patch open a new patch in MaxMSP and paste.
 * For the Wiring boards v1 the on-board LED is on pin 48,
 * on Wiring S the on-board LED is on pin 15.
