In this tutorial I will show you how to make your own "Laser Security Alarm System" or a "Laser Sensor" on breadboard. This is similar to my previous video "Dark Sensor."
Its awesome once you complete the circuit and fun to play with. You can make this Laser Tripwire Alarm and protect your room from intruders :D
You can even add multiple mirrors from different angles and focus it on the LDR for a greater effect.
COMPONENTS REQUIRED:- LDR
L.E.D
BC547 Transistor
330 ohm resistor
9v Battery
Buzzer
Breadboard
