Hi friends!
welcome to crazytronics
In this video I am going to explain you how to make simple laser security system using transistor,
You can use this circuit in your home for security
For this project you need following components
transistor (BC547) x1
Resistor (2K ohm) x1
Buzzerx1
Breadboard x1
Battery (9V) x1
Battery connector x1
LDR x1
Jumper cables
