Arduino Nano Night Light Kit - Build a Light-Responsive LED with LDR and PWM

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 a night light that automatically glows dim when the room is dark and bright when you turn on the lamps. With this kit, you'll build exactly that - a smart LED circuit that senses ambient light using an LDR and controls brightness with PWM, all programmed on an Arduino Nano. It's the perfect first step into physical computing for a young maker.

What You'll Build

You'll assemble a compact night light on a half breadboard, wire the LDR sensor to read changing light levels, connect three white LEDs as your output, and upload code that makes brightness react instantly to the room. By the end, you'll hold a gadget that dims and brightens on its own - ready to sit on your desk or bedside.

What You'll Learn

• Reading analog sensor values with analogRead() from an LDR circuit
• Controlling LED brightness using PWM and analogWrite() on Arduino pins
• Building a voltage divider with an LDR and fixed resistor to sense light intensity
• Wiring components on a breadboard and connecting them to an Arduino Nano

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Designed for students in CBSE Class 6-8 taking their first dive into electronics, as well as participants in ATL Tinkering Labs and summer STEM workshops. It's also a hit with young makers preparing a working model for school science exhibitions - no prior coding experience needed, just curiosity.

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.
