Magic Wand with Machine Learning

Magic Wand using ESPectro32 board, powered by TensorFlow Lite for Microcontrollers and PlatformIO. Previously I made a similar project but using Arduino Nano 33 BLE Sense board.

As ESPectro32 is based on ESP32, this project should be easily adapted for other ESP32 board. You can change this to #define ESPECTRO32 0 in output_handler.cpp. But you need to have some kind of display to let user know what is the predicted gesture. ESPectro32 has on-board LED Matrix to display the predicted gesture.

Interaction demo video is quite similar to this:

Prerequisites

Train

You can train the Machine Learning model to recognize your own gesture, or even other gestures than Magic Wand. The model and training code is here.

I'm thinking to create some guideline to do that training in Azure Machine Learning, let me find the time.
