How to make a DIY Automatic On & Off Light Circuit With LDR Sensor for Night Time | Science Project

In this video, I will show you how to create a simple automatic street light with ldr sensor and BC547 Transistor.
This Circuit Automatically Turns On & Off the light bulb depending on the time of the day.
When it's day and the place is light, then the circuit turns off the light bulb and when it's dark it turns on the bulb.
It's very simple to build, with just 3 components
*BC547 Transistor
*LDR sensor
*220k ohm Resistor
