Bluetooth HID using just an ESP32 (inc Bluetooth macro keypad)
In this video we are going to take a look at using the built-in Bluetooth of the ESP32 to emulate a Bluetooth Keyboard.
With some ESP32 development boards starting at less than $5 delivered, this is a really inexpensive and simple way to create wireless custom keyboards such as a Macro keypad that could be used for controlling scenes in OBS.
We’ll first look at how to use the ESP32 HID keyboard library and then I will show you how I used this to build a battery powered Bluetooth Macro Keypad.
