Track your punches with precision on Adafruit IO using this accelerometer-powered Boxing Glove tracker with an  ESP32-S2 or ESP32-S3 TFT! In this guide we'll just refer to the ESP32-S3 TFT.

This project allows you to build your custom Boxing Glove Tracker using a Feather ESP32-S3 TFT running CircuitPython with an ADXL345 accelerometer. The ESP32-S3  TFT reads accelerometer data to measure the force of punches you throw.

The data collected by the accelerometer will then be sent to Adafruit IO, where you can visualize and analyze your training performance over time.

Using PyLeap

You can quickly transfer this project to your ESP32-S3 TFT via a WiFi connection using the PyLeap app.

PyLeap is a free app available for iOS, iPad and Android devices. It can be downloaded from the Apple App Store or Google Play Store. It allows users to easily download code files and assets and transfer them to their Adafruit devices using Bluetooth Low Energy (BLE) or WiFi.

This project is perfect for folks that want to enter the electronics and IoT world. It's also handy for anyone who trains in boxing and wants to track their progress and improve their technique! Below are some parts you'll need to have before starting this project. 

Let's get started!
