So how does it work. when the laser is blocked from the head of the module the piezo will

alarm up.

so lets start. :):):):):):):):):):):):):):):):):):):):):)!!!!!!!!!!!!!

1. Laser Detector (1)

2. Piezo (1)

3. Laser (1)

4. Arduino (1)

The laser detector pins are:

VCC to 5V

GND to GND

OUT to pin 11

the laser pins are:

red wire or positive to pin12

blue wire or negative to GND

The piezo wires are:
