Smart Light Sensor LED Controller

Beginner Arduino Project
1-2 hours

Automatic LED lighting system that responds to ambient light levels. LED brightness adjusts based on light sensor readings - perfect for night lights or automatic room lighting.

Smart Light Sensor LED Controller

Project Overview

Create an intelligent lighting system that automatically adjusts to ambient light conditions! This project teaches you about analog sensors, PWM output, and responsive control systems.

Using a photoresistor (Light Dependent Resistor), the system measures ambient light levels and automatically controls LED brightness. When it gets dark, the LED brightness increases, and when it's bright, the LED dims or turns off completely.

This project demonstrates fundamental concepts used in smart home lighting, automatic street lights, and energy-efficient building systems. You'll learn about sensor calibration, analog-to-digital conversion, and smooth control algorithms.

  • Understanding digital pin outputs
  • Using delay() functions for timing
  • Creating loops and sequences
  • Basic circuit building
