Seeing eye mouse

Don writes – “If I had to put it succinctly, I would describe it like this: The Seeing-Eye-Mouse is “glue” – it gives you a simple to use interface to a computer mouse’s operation to make it easy to use the mouse in various ways for various purposes. The simplest method of operation lights 4 LEDs (forward, back, left, right) in response to moving a plugged-in mouse. It’s also used on a Mini-Sumo Robot as a proof of concept.” – Link.
