Arduino Script

/* Tested on arduino mega256 R3 arduino code v1.0.4
connect arduino gnd to - on sensor
connect arduino 5V to middle pin on sensor
connect arduino pin 11 to the S on the sensor
Tones are produced by chaning the delay time in the for loops
You will see a difference in the intensity of the laser beam
between the two loops. Play with the numbers.
