Build an Automatic Staircase Light with Arduino Uno + LDR — A Beginner’s Smart Home Project

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

Imagine walking up a dark staircase and seeing the steps light up automatically the moment you approach — then turn themselves off 30 seconds later. That’s exactly what you’ll create with this kit. Using an Arduino Uno, a PIR motion sensor, and two LDR light sensors, you’ll build a hands‑free smart lighting system that conserves energy and makes daily movement safer.

What You'll Build

You’ll assemble a working prototype of an automatic staircase light that switches on only when two conditions are met: the ambient light is low, and someone is moving nearby. The LEDs stay on for exactly 30 seconds, then turn off — perfect for stairways, hallways, or any dark passage in your home.

What You'll Learn

• How PIR sensors detect motion and send signals to a microcontroller
• Using an LDR to measure ambient brightness and trigger actions only in darkness
• Programming the Arduino Uno to read two sensors, control LEDs, and manage timing
• Wiring a complete circuit on a breadboard and powering it with a 9 V battery
