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.

There’s not much to it – almost all optical mouse sensors have a rather simple serial interface (clock and data) suitable for linking to a microcontroller like Arduino. Anyway, tutorials available ...

Building an Arduino Mouse Choosing the right electronics is essential for a responsive mouse. An Arduino Pro Micro is a great choice because it connects easily via USB.

In this tutorial, I will show how you can handle the optical sensor inside a cheap optical-mouse for your next microcontroller project. Hope, this will allow your preferred microcontroller to look at ...
