ESP32 Bluetooth Keyboard as a Game Controller for Retro Home Computers 

The ESP32's built in Bluetooth Low Energy module allows you to turn it into a programmable Bluetooth keyboard. In this video I'll show you how to get the keyboard code up and running and then we'll use it to build a gamepad that mimics key presses on your keyboard. This will let you use the gamepad in any games that don't support game controllers.
