How to make a laser security system with Arduino
In this tutorial we will learn how to make a laser security system with Automatic Room Light Using Arduino.
For this tutorial we will use IR Sensor, Laser Module KY-008, Buzzer, Led and Arduino UNO.
Hardware Required :

Project circuit diagram is shown below.
KY-008 Laser Module
This Keyes device is one among the more common devices found in Arduino sensor kits. including other components, it are often wont to create trip wires or optical effects.
The KY-008 is especially neat because it are often directly powered from an Arduino output pin because it only draws 30 mA from the processor that has outputs rated for 40 mA.
WARNING : Lasers are often harmful to the eyes and you ought to never look directly into the beam.
This is a really simple component that’s wont to make simple sounds with Arduino. you could not play an MP3 with it but it’s just fine for an alarm . You can, of course, use any buzzer that’s available, the goal is to only make a sound.
