💡🔁 Light Activated Switch with IC555 Timer: DIY Automatic Control Circuit

In this video, learn how to build a light-activated switch using the IC555 timer and an LDR (Light Dependent Resistor). This simple and effective circuit automatically turns an LED or device ON or OFF based on ambient light levels — ideal for night lamps, garden lights, or light-sensitive alarms.

What You’ll Learn:
How to use an LDR as a light sensor in a 555 timer circuit
Configuring IC555 in Schmitt trigger or monostable mode
Controlling an LED or output device based on light intensity
Fine-tuning the sensitivity using resistors

Components Used:
IC555 Timer
LDR (Light Dependent Resistor)
Resistors and Potentiometers
LED (or other output device)
Power supply, breadboard, and jumper wires

This project is perfect for beginners looking to explore sensor-based automation using basic components.
