Intelligent Staircase LED Sequencer Kit with Arduino Mega + Relay
Add Motion-Activated Intelligence to Every Step with This Arduino Mega Staircase Sequencer Kit
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 toward your staircase in the dark and having each step light up one by one, tracing your path upward or downward. That's exactly what this kit builds: a 12-step LED sequencer that uses two PIR motion sensors to detect direction and triggers relays to illuminate LEDs in a smooth chase pattern. It's a real-world smart home upgrade that you assemble, program, and install yourself.
What You'll Build
You'll put together a fully functional staircase lighting system on a pair of PCB prototype boards. The final build listens to a PIR at the top and another at the bottom, decides which way you're moving, and then fires relays in sequence to create a walking light effect. Mount it along your actual staircase or build a display model—the circuit works for 12 steps, and the logic handles edge cases like mid-staircase activation gracefully.
What You'll Learn
- Programming an Arduino Mega to read multiple sensor inputs and control a large relay bank
- Interfacing HC-SR501 PIR modules and tuning timing and sensitivity for reliable motion detection
- Wiring and managing 12 independent 5V relay channels without noise or false triggers
- Designing a soldered prototype on PCB boards, including diode protection and power filtering

Who This Kit Is For
B.Tech ECE and EEE students will find this project a perfect lab companion for embedded systems and home automation coursework. Smart India Hackathon teams can use it as a prototype for intelligent building challenges, while makers at IITs, NITs, VIT, or BITS Pilani can extend the concept into full dorm-room installations. If you've already built basic Arduino projects and want to tackle relay sequencing, power management, and sensor fusion, this kit meets you at that level.
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 inside the box and start a chat with the AI companion. It knows every connection, pin mapping, and code block for this kit. If you still need help, message us on WhatsApp.
Can I adapt this for fewer than 12 steps?
Yes. The Arduino Mega has plenty of I/O, so you can simply connect only the relays you need and modify the code to sequence a shorter chase. The AI companion can guide you through the small software adjustments.
Is soldering experience required?
You'll build the relay board and LED matrix on prototype PCBs, so basic soldering skill is assumed. The included iron and solder get you started, and the build guide includes clear wiring diagrams if you're still developing your technique.
What power supply do I need beyond the included adapter?
The 12V adapter powers the entire system, including the Arduino via its onboard regulator and the relay coils. No external supply is needed unless you later add high-wattage LED strips; then you'd size a dedicated PSU accordingly.
PIR at top and bottom trigger 12 step LED relays sequentially in the detected travel direction.
