How does a Mouse know when you move it? || How Does a Computer Mouse Work?

You've probably used a mouse today. But do you know how it works?
Check out https://www.pcbway.com/ for all kinds of PCBs, easy ordering, and quick delivery. Take a look at their PCB Assembly, for an inexpensive population of the components on your PCBs.

In this video, we explore the different parts of a computer mouse and we'll focus on the optical navigation system. Specifically, we'll look at how exactly computer mice can track their movement on a mouse pad. Finally, we take a look at the difference between gaming mice and normal mice, and we explore DPI or dots per inch and how different mice have different amounts of DPI.
