USBKWA (USB Keyboard Web App) turns a large tablet or any device with a Web browser into a USB keyboard. Anyone having difficulties using a regular keyboard may find a touch keyboard easier to use.
This will not work with Arduino IDE 1.6.5 (or below) or with non ESP32-S2/S3 devices (e.g. Arduino UNO, Arduino MEGA, etc.). To use this library you need to have Arduino core for the ESP32 installed.
