How do Scroll Wheels Work? 🖱🛠🔬

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. Have you ever scrolled a scroll wheel and wondered how it scrolls? Scroll is a rather strange word, isn't it? Anywho, in this video, we're going to explore the inside of a computer mouse and look at two different scroll wheels: an optical rotary encoder, and a magnetic rotational position sensor, and see how they are used to measure up and down rotational movement in a computer mouse scroll wheel. We're also going to explore the push button under the scroll wheel as well as the free-spinning vs. ratchet mode of the scroll wheel.
