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 ...

If your pointing device is a mouse, turn it over. The chances are you’ll see a red LED light if you’re not seriously old-school and your mouse has a ball, this light serves as the illumination for a ...

The first optical mice had to be used on a specially printed mousepad with a printed grid that the four-quadrant infrared sensor could detect. Later, mice swapped the infrared sensor for an ...

Mechanical ball mice are dead; long live optical and laser mice. While both are basically shaped the same and achieve the same purpose, what exactly are the differences between optical and laser mice?

This Design Idea utilizes an optical computer mouse's sensor for measuring rotation of a disk which can be mechanically connected to any sort of rotating apparatus. One feature is to allow adjustment ...
