Foreword:

As the ultimate anti-theft alarm device in sci-fi movies, laser alarm device has its invisible infrared ray available for experience and utilization, allowing you to catch the thief easily… Actually, it can be also used in this way.

Step 1:

Your pet at home may be disobedient or go to a prohibited place. Why not making a laser anti-theft alarm emitter if you have no time to guard it?

Step 2:

Today, I will introduce a simple laser alarm device model to you.

Principle: A laser emitter sends a light beam and another laser receiver receives the laser beam. When the connection is established, the alarm will be triggered if any object blocks the laser beam.

Component:

DFRduino UNO R3(similar as Arduino UNO R3

Gravity:Digital RED LED Light Module

Gravity: Digital Buzzer For Arduino

Laser Transmitter

Toggle Switches

9V battery

Jumper Wires

Making:

Step 3:
