M5StackをBLEキーボードにする

A classic bluetooth-controlled USB Rubber Ducky clone built with ESP32 boards.

This project is a Zephyr-based firmware for converting vintage typewriters (like the Brother AX110) into modern USB and Bluetooth Low Energy (BLE) HID devices. It uses the Zephyr RTOS to handle USB device stacks, BLE advertising, and input matrix scanning.

Here I use Flex sensors, ESP 32 and ESP-32-BLE Keyboard library to create a ble keyboard.

Emulates a BLE keyboard with the ESP32 to flip pages, useful when playing an instrument and reading sheet music.
