 * Don't worry about the LED (which you can connect to digital 13 if you want) as it doesn't contribute anything new.
 * Attach a potentiometer to 5v and Ground (two outer connections), and the sensor (central connection) to Analogue in 5.
 * 
 * In fact, the code below reads ALL the analogue pins, so you can use any...
