Sport Form Coach Kit: Build a Wearable Posture Trainer with Arduino Nano & MPU6050

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

During cricket nets, basketball drills, or gym sessions, the difference between a good rep and a future injury often comes down to one thing: posture. This kit turns an Arduino Nano and an MPU6050 accelerometer/gyroscope into a personal form coach you wear on your upper back. As soon as you slouch or round your shoulders, it gently vibrates — not to annoy, but to remind you to straighten up. After a few sessions, correct form becomes muscle memory, and the vibration stops because you stop slouching. It’s wearable biofeedback, engineered by you.

What You'll Build

You’ll assemble a slim, battery-powered unit that straps under your jersey. The MPU6050 measures your spine angle 100 times per second, an onboard LED glows when your posture is good, and a coin vibration motor pulses if a pre-set slouch angle lingers for more than 5 seconds. The threshold and sensitivity can be tweaked in code, so whether you’re a fast bowler trying to keep your front arm up or a weightlifter avoiding a rounded back, the feedback is custom to your sport.

What You'll Learn

• Reading 3-axis accelerometer and gyroscope data from an MPU6050 over I2C
• Applying a complementary filter to stabilize tilt angle measurements in real time
• Driving a haptic motor through a BC547 transistor with PWM for adjustable vibration intensity
• Integrating a wearable circuit into a sports context — managing sweat, movement, and battery life

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

Built for the overlap of sports and STEM. CBSE Class 11-12 students can combine physics and physical education in one project, B.Tech ECE/EEE students can use it as a foundation for wearable health device research, and ATL Tinkering Lab innovators will find it ready to prototype Smart India Hackathon sports-tech ideas. Even cricket academy coaches use it to show athletes what “straight back” actually means — because a sensor never misses a slouch.

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.
