How to Build a simple input device
This page describes how to build a simple three button keyboard or “alternative input device”.
This page describes how to build a simple alternative input device that connects to the serial port. This device can have three buttons and stay simple; more buttons are possible, but they would make things more complicated. The hardware is as simple as three light switches. The software is a little bit more complicated, but not much.
This could come in handly for a couple of projects I have in mind.
