The idea early on was to leverage existing Arduino libraries to connect with a standard USB mouse, specifically, the hardware would take the form of an Arduino Mega 2560 with a USB Host Shield.

The device uses a Arduino Micro to read data from the keyboard and communicate as a HID device over USB. It connects to the keyboard using the original mini-DIN connector, and is housed in the ...

This causes problems when switching between devices — for example, the pendrive won't work if the keyboard was used first, and vice versa. There’s no .end () or cleanup function in the current Arduino ...
