Arduino Nano Kit: Build a Motion-Activated Light for Elderly Safety

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

Create a smart light system that automatically dims when nobody is near and brightens on approach-just like the street lights you see in smart cities. This kit teaches you how a simple Arduino Nano can read light levels and motion to help care for elderly family members, ensuring they never walk in the dark.

What You'll Build

You'll assemble a working motion-sensing night light that switches on brightly only when someone approaches in the dark. The LDR (Light Dependent Resistor) checks the ambient light, and the PIR motion sensor detects movement. When both conditions are met, the 3W white LED illuminates gently-saving energy and providing soft, automatic illumination for elderly corridors or bathrooms.

What You'll Learn

• How to read analog signals from an LDR and digital signals from a PIR sensor using Arduino Nano.
• Controlling high-power LED brightness with a MOSFET as a switch (PWM dimming).
• Wiring sensors and actuators on a breadboard without soldering.
• Understanding conditional logic in Arduino code to automate a real-world helper.
