Arduino Nano Wearable Posture Trainer: MPU6050 Slouch Detector with Haptic Feedback

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

Poor posture isn't just a habit - it's a health risk that creeps in silently. This kit lets you build a wearable device you strap to your upper back. It uses an MPU6050 accelerometer-gyroscope to measure your spinal tilt continuously, and a coin vibration motor buzzes after you've slouched for several seconds. Think of it as a silent coach that nudges you upright without any screen, perfect for long coding sessions, study marathons, or desk work.

What You'll Build

You'll assemble a compact, battery-powered posture corrector that you can wear under a shirt. The Arduino Nano reads roll and pitch angles from the MPU6050, runs a real-time slouch-detection algorithm, and triggers a haptic alert via a BC547 transistor-driven vibration motor. You'll calibrate the device to your neutral sitting angle, set the sensitivity, and even log posture events through the serial monitor. The final device is a fully wearable reminder that trains your body to sit straighter.

What You'll Learn

• Interfacing MPU6050 with Arduino Nano over I2C and reading Euler angles
• Implementing a slouch-detection algorithm with timers and threshold logic
• Driving a small DC vibration motor using a BC547 transistor and flyback diode
• Building a wearable circuit on a breadboard and packaging it with a velcro strap

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This project is a natural fit for CBSE Class 11-12 students exploring sensor-based health devices, B.Tech ECE/EEE undergraduates designing wearable prototypes for hackathons like Smart India Hackathon, and ATL Tinkering Lab mentors who want a ready-to-run posture trainer. It's also ideal for IIT/NIT/VIT/BITS students building proof-of-concept wearables for biomedical or ergonomics research.

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.
