Automatic Street Light System Using LDR

Automatic Street Light System Using LDR

Automatic Street Light System using LDR, an innovative project

designed to demonstrate the principles of automatic lighting control.

This kit includes LED lights, a 9V battery, a 555 Timer IC, a

potentiometer, and other essential components, all mounted on a

project model and circuit board.

This system uses a light-dependent resistor (LDR) to automatically

control the street light based on ambient light conditions, providing

hands-on experience with practical electronics and automation.
