I’ve always wondered this because I understand how wired mouses work but how do wireless mouse work?
In: Technology
There are two cases for wireless mice, where either you get a USB dongle (usually a small looking USB stick) or don’t.
In the case that you get a USB dongle, the mouse is already set to start listening for and talking to that USB dongle. Once that dongle’s plugged into your computer, your computer can talk to the dongle. So when you move your mouse, those signals get broadcast to your dongle, which then talk to your computer and moves the mouse the way it’s supposed to.
In the case that you don’t get a dongle, likely you’ve got a Bluetooth mouse. Basically how Bluetooth works is that you’ve got devices like headsets and keyboards screaming into space for someone to notice them. This signal is used by another device (like a computer) to pair, which turns that screaming into a polite exchange of signals, like keyboard strokes and audio playback. So once your Bluetooth mouse is paired with your computer, it’ll send the exact same signals.
