Maybe it wouldn’t be so boring if the input device was a nunchuck ... so that’s trivial to interface to an Arduino or other small microcontroller. The only issue is making the connection.

Simply by uploading new firmware with the Arduino Device Firmware Upgrade, it’s easy to have your old Arduino board gain some of the features of newer boards such as the Teensy or Leonardo.

This means that while Raspberry Pi can function as a fully-fledged mini-computer capable of running multiple apps at once, while Arduino can only handle limited input and output controls.
