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

Step 1: Gather Your Body Parts

1. Laser Detector (1)

2. Piezo (1)

3. Laser (1)

4. Arduino (1)

Step 2: Connect It to Your Body

The laser detector pins are:

VCC to 5V


OUT to pin 11

the laser pins are:

red wire or positive to pin12

blue wire or negative to GND

The piezo wires are:

positive to pin 13

negative to GND

Step 3: Give a Messge to Your Brain to Work
