TFT Polar Plot Wind Rose Kit with Arduino Uno
Build a Wind Rose Polar Plot on TFT with Arduino Uno – Data Visualization Kit
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Ever wondered how meteorologists track wind patterns? This kit lets you build a real-time wind rose that draws wind direction and speed as a polar diagram on a colour TFT. As the QMC5883L compass senses orientation, the display updates hourly spokes, painting a full picture of airflow over a full day. Ideal for science fair exhibits, weather station prototypes, or simply satisfying curiosity about data visualisation.
What You'll Build
A working polar wind rose that updates every hour. The TFT screen shows a radial axis with 24 spokes, each representing an hour, with bar lengths proportional to wind speed and colours indicating low, medium, or high breezes. Simply orient the sensor in the breeze and watch the history unfold—perfect as a desk display or a teaching aid for understanding circular graphs.
What You'll Learn
- Reading a QMC5883L digital compass sensor over I2C protocol
- Driving a 1.8-inch TFT display with the ST7735 library and drawing shapes
- Converting compass headings into polar coordinates for radial bar graphs
- Storing hourly data in memory and updating a living rose diagram without clearing earlier spokes

Who This Kit Is For
Designed for curious young minds and beginners—perfect for CBSE Class 6–10 science projects, ATL tinkering labs, and introductory Arduino workshops. B.Tech ECE/EEE students will also find it an engaging way to explore I2C communication and display programming. Suitable for ages 10+ with minimal adult guidance, or self-learning from age 14 upward.
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 on the box to chat with our AI companion; it knows every wire and line of code for this project. For anything it can’t solve, WhatsApp us—we reply within hours.
Does this kit require soldering?
No, everything plugs into the included breadboard. Just use the jumper wires to connect the Arduino, compass module, and TFT display—no soldering iron needed.
How soon will I see a full 24‑hour rose?
Each new reading plots a spoke immediately; after the first hour you’ll see the start of the diagram. Over a full day the polar rose fills in automatically, storing up to 24 spokes. You can also simulate past hours by tilting the sensor manually while testing.
Is the compass affected by nearby metal?
Yes, the QMC5883L is sensitive to magnetic interference. Keep it away from iron tables, magnets, or large metal objects. The kit guide includes a quick calibration routine to offset any soft‑iron distortions in your environment.
