Arduino Nano Senior Movement Alert Kit - A DIY Toilet Nightlight for Fall Prevention

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

Nighttime falls in the bathroom are a leading cause of injury among seniors. This kit lets you build a subtle, motion-activated LED ring that mounts under the toilet rim, illuminating only when it's dark and someone approaches. Within a weekend, you'll create a safety device that helps elderly family members navigate their bathroom without fumbling for switches or being startled by harsh overhead lights.

What You'll Build

A discreet WS2812B 12-LED ring that glows softly for 60 seconds when the PIR sensor detects movement and the LDR confirms low ambient light. Designed to sit out of sight beneath the toilet seat, it offers just enough guidance for safe use without disturbing sleep patterns. The entire circuit runs off a standard 5V supply and fits neatly on a breadboard, ready for a permanent enclosure if desired.

What You'll Learn

• Interfacing an HC-SR501 PIR sensor with Arduino Nano to trigger events on motion detection
• Using an LDR with a voltage divider to read ambient light levels and enable night-only operation
• Controlling an addressable WS2812B LED ring - setting colour, brightness, and duration
• Writing Arduino code that combines sensor inputs with timed output for real-world automation

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This project is ideal for CBSE Class 11-12 students exploring sensor-based electronics, B.Tech ECE/EEE undergraduates prototyping assistive technologies, and participants in Smart India Hackathon or ATL Tinkering Lab challenges. It also suits makers from IIT/NIT/VIT/BITS who want a practical elderly-care gadget or families looking for a meaningful DIY activity that directly helps ageing relatives. If you have a basic comfort with breadboards and Arduino IDE, you're ready to start.

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.
