A configurable bluetooth keyboard that utilizes the touch sensors on ESP32 as keyboard keys to send keystrokes to the connected device

custom case i designed to mount on my laptop's SD card reader to make the "keyboard" even more portable

preview the 3d *.stl files directly in github -->

[note: final designs are different than the rendered video cuz i cant be bothered to update the video when the design updated too \o_o/]

open the project in VSCode and install platformio extension

• define the pins and their corresponding letters you want to use in the file: includes/KEY_CONFIG.h

• inside the TOUCH_KEYS array, initialise your keys using the format:

  TouchKey( <<pin number>>, '<<letter to press>>', <<optional threshold for *this* pin>> )
  

  (refer sample config in that file)

for the pin number, make sure to refer the pinout diagram of your ESP board and select the touch pins only (touch pins are prefixed with T)

• you can edit the device's bluetooth name, manufacturer's name & the battery level in include/CONFIG.h

after you're done configuring, build the code and upload to your board

• improve touch processing algorithm to imitate a real keyboard's
• make a 3d printed case

This program uses the amazing ESP32-BLE-Keyboard library made by T-vK
