Thanks for the link :slight_smile:

The tricky part is the library, that implements the USB Keyboard (HID) protocol. The Uno USB connector cannot be used for that purpose, because it implements an USB Serial device.

There exist Arduinos, which allow to configure the on-board USB port for various protocols. E.g. the Leonardo appears as a generic keyboard and mouse on its USB connector, no need for any additional circuitry.
