Project Overview

This project aims to develop a high-precision Velocity Based Training (VBT) device. Using the BMI270 6-axis IMU and BMM150 magnetometer, the device tracks the vertical displacement and velocity of a barbell during strength training.

Technical Specifications

• Microcontroller: Arduino Nano 33 BLE Rev2 (Cortex-M4F)
• Sensors: * BMI270 (Accel/Gyro) - 16-bit resolution
  • BMM150 (Magnetometer) - for heading drift correction
• Communication: Bluetooth Low Energy (BLE) to Web-App
• Algorithm: Madgwick Filter for Sensor Fusion & Orientation Estimation

Project Roadmap

1. Phase 1: Hardware Integration & Raw Data Acquisition (I2C)
2. Phase 2: Sensor Fusion (Madgwick Algorithm) & Gravity Compensation
3. Phase 3: Velocity Integration & Filtering (Zero-Velocity Update logic)
4. Phase 4: BLE Data Transmission & Web UI visualization

How to Use

1. Clone the repository.
2. Install Arduino_BMI270_BMM150 and MadgwickAHRS libraries.
3. Flash the src/main.ino to your Arduino.
