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 ...

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 ...

Finding a mouse that achieves the perfect balance between sensitivity and accuracy might seem next to impossible. Laser-based mice offer high sensitivity, but they tend to cause jittering. On the flip ...
