About the Project

This project uses an LDR (Light Dependent Resistor) to detect light and control an LED automatically.

• When the surroundings become bright → LED turns ON
• When the surroundings become dark → LED turns OFF

This is a simple beginner project to learn:

• Analog sensors
• Automatic control
• Arduino programming
• Sensor value reading

Components Required

• Arduino Nano / Uno – 1
• LDR Sensor Module – 1
• LED – 1
• 220Ω Resistor – 1
• Breadboard – 1
• Jumper Wires
