Arduino Wind Vane Direction Indicator Kit for Kids
Build Your Own Compass Rose Wind Direction Indicator with Arduino Uno
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
What if you could look out the window and instantly know which way the wind is blowing - not from a screen, but from a physical compass of LEDs glowing on your desk? This kit places eight reed switches in a compass rose around a central point. A small magnet attached to a DIY wind vane (made from cardboard or 3D-printed parts) triggers the closest reed switch as the vane swings, lighting up an LED for North, South, East, West, and the four ordinal directions. It's a hands-on weather station that turns invisible wind patterns into a quiet light show.
What You'll Build
You'll assemble a direction indicator that reacts to real wind or breath. The Arduino reads which reed switch circuit is closed by the passing magnet and lights the corresponding LED. The result: a desk-top compass rose that mirrors a rooftop wind vane, perfect for a science fair, weather lesson, or just satisfying curiosity about the air around you.
What You'll Learn
- How reed switches sense magnetic fields and behave like switches
- Digital input pin reading with pull-up or pull-down resistors
- Mapping input states to outputs - turning sensor data into visual direction
- Building a simple wired compass that mimics real weather vanes used by meteorologists

Who This Kit Is For
Curious kids (ages 5-15) who love fizzy science models, CBSE Class 11-12 students needing a physics or electronics project, and ATL Tinkering Lab mentors running weather-themed workshops. Also fits Smart India Hackathon juniors exploring environmental sensing, or B.Tech ECE first-years learning sensor integration. Makes a memorable gift that bridges nature and code.
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 to chat with the AI companion trained solely on this kit's circuit. It'll walk you through wiring, code, and troubleshooting. For a human backup, WhatsApp us.
Does the kit include a physical wind vane or compass housing?
No - that's part of the creativity. The kit gives you the electronics to sense magnet positions. Build the vane and compass rose from cardboard, foam board, or 3D print using our bonus template (link in AI companion).
Can I test it indoors without real wind?
Absolutely. A gentle blow across the vane or a hand-wave with the magnet near the reed switches will trigger the LEDs. Perfect for classroom demos even on calm days.
What if an LED doesn't light up even though the reed switch is closing?
First, check your resistor and LED polarity. Then open the AI companion and enter the fault description; it will help you isolate whether the issue is wiring, code, or a defective reed switch. If a part is faulty, we'll replace it.
Door Monitoring - Reed switches in a compass rose detect magnet on a wind vane to show N/S/E/W direction on LEDs.
