Suntracking Arduino scatch

 /*
 Arduino Sun Tracker
 Demonstrates analog input by reading analog sensors on analog pin 0 to 3 and
 turning on and off a PWM signal on digital pin 10 and 11.
 The amount of time the PWM signal will be switched on depends on
 the value obtained by delay() function.

 * Note: because most Arduinos have a built-in LED attached
 to pin 13 on the board, the LED is optional.
