Arduino Mega Stair Light Kit - Motion Sensor Directional Step LEDs
Arduino Mega Motion Sensor Staircase Lighting Kit - Illuminate Steps in Direction of Travel
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
No more fumbling for light switches on dark staircases. This kit lets you build a system that senses your approach from either end and lights each step precisely as you move, then turns off behind you - a real home security upgrade that feels smart and responsive. Using two PIR sensors and 12 LEDs controlled via relays, it creates a flowing light path that guides residents and deters missteps, all powered by an Arduino Mega at the core.
What You'll Build
A fully functional bidirectional staircase illuminator. When someone climbs from ground floor, the bottom PIR detects motion and sequentially triggers white LEDs from step 1 to step 12, lighting only the steps ahead. Coming down? The top sensor activates the reverse sequence. It's a practical project that adds both safety and a showpiece automation element to any home or hostel.
What You'll Learn
- Interfacing multiple PIR sensors and relay modules with the Arduino Mega's numerous digital I/O pins
- Implementing time-based direction detection logic to differentiate ascending and descending motion
- Driving 12V relay coils safely using flyback diodes and managing independent LED channels
- Prototyping a complete, wall-mountable home automation system on PCB boards with robust wiring

Who This Kit Is For
This advanced kit suits B.Tech ECE/EEE students crafting semester projects or capstone submissions, Smart India Hackathon teams prototyping safety-centric home automation, and diploma students exploring microcontroller-based systems. It's also perfect for ATL tinkering labs running advanced workshops where participants already have basic Arduino proficiency and want to tackle multi-sensor integration.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project - accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code to access the AI companion, which provides step-by-step guidance and answers common pitfalls. You can also reach our support team on WhatsApp for real-time help.
Can I extend this to more than 12 steps?
Yes, the logic scales. The AI companion explains how to add more relay modules and LEDs, and modify the code for additional steps using the Mega's extra I/O pins.
Does the system work in total darkness?
Absolutely. The PIR sensors detect infrared heat changes, so the staircase lights activate even in pitch-black conditions, making it ideal for nighttime safety.
What happens if a pet or object triggers a sensor?
The system responds to any motion. You can adjust PIR sensitivity and trigger delay via onboard potentiometers to minimise false activations from small animals, and the AI companion guides you through this calibration.
Home Security - Two PIR sensors at top and bottom of stairs trigger 12 step LEDs to light sequentially in the direction of travel.
