Auto Light Energy Saver Kit with Arduino Mega + Relay
Auto Light Energy Saver Kit – Arduino Mega Smart Staircase Lighting
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Build a smart staircase lighting system that automatically switches on LED strips in the direction you’re moving. As you approach, a PIR sensor detects motion at the top or bottom and triggers a cascading sequence of 12 relay-controlled lights, lighting your path ahead without wasting energy behind you. Perfect for college hostels, multi-floor apartments, or eco-conscious smart homes.
What You'll Build
A fully functional 12-step directional LED staircase lighting system controlled by an Arduino Mega. Two PIR sensors at each end detect motion and direction, activating the corresponding sequence of LEDs from top to bottom (or bottom to top) via relays. The system consumes power only on the needed path, making it an ideal energy-saving addition to any staircase.
What You'll Learn
- Detecting motion direction with dual PIR sensors
- Programming sequential relay control on Arduino Mega
- Designing a 12-channel LED relay driver circuit
- Soldering and assembling a multi-component project on prototype PCBs

Who This Kit Is For
This kit is ideal for B.Tech ECE and EEE students working on home automation projects, Smart India Hackathon teams, and final-year engineering students at IITs, NITs, VIT, BITS, and other institutions. It’s also suited for motivated CBSE Class 12 students with prior Arduino experience who want to go beyond basic projects.
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?
The AI companion gives step-by-step feedback specific to this staircase lighting build, and our team can help via WhatsApp if you hit a hardware snag.
Can I replace the 12 LEDs with a longer LED strip?
Yes, the relay modules can drive 12V LED strips directly, provided the total current stays within each relay’s 10A rating. Only minor wiring adjustments are needed.
Does this require external wiring to the staircase?
The kit builds a standalone prototype on PCB boards; you can later extend the sensor and LED wiring to fit an actual staircase using terminal blocks or soldered connections.
Is the soldering iron included, and do I need previous soldering experience?
Yes, a soldering iron and solder wire are included. Basic soldering skill helps, but the AI companion includes practical tips for assembling the relay driver boards.
Energy Saving — PIR at top and bottom trigger 12 step LED relays sequentially in the detected travel direction.
