DIY Wind Direction Indicator Kit - Build a Compass Rose with Arduino Uno & Reed Switches

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

Turn a simple magnet into a wind vane sensor. This kit walks you through building a 360-degree compass display-place eight reed switches around a circle, attach a magnet to your wind vane, and the Arduino lights up exactly the LED that matches the wind's direction. No weatherproofing needed, just pure electronics exploration that connects your code to the physical world.

What You'll Build

You'll assemble a miniature compass rose on a breadboard, then write an Arduino sketch that constantly checks which reed switch the magnet has closed. The moment the wind shifts, the corresponding LED glows-North, South, East, West, and the points in between. It's a real-time wind direction readout you can test with a fan or a gentle breath.

What You'll Learn

• How reed switches work as magnetically triggered digital inputs
• Reading multiple digital pins from an Arduino Uno in a loop
• Mapping inputs to LED outputs using conditional logic
• Designing a physical layout that mimics a geographic compass

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Perfect for young makers age 10 and up who want to see code do something physical, CBSE Class 11-12 students building an interactive physics or geography project, ATL Tinkering Lab members exploring sensors, and B.Tech ECE/EEE freshers getting hands-on with Arduino inputs. It's simple enough for a parent-child weekend build, yet foundational enough to spark weather station ideas for Smart India Hackathon.

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.
