One of the attractive features of early optical computer mice was their lack of moving parts. The idea is that fewer moving parts translate into less mechanical wear and longer life. But even though ...

Wanting to experiment with using optical mouse sensors but a bit frustrated with the lack of options, [Tom Wiggins] rolled his own breakout board for the ADNS 3050 optical mouse sensor and in the ...

Unlike a mechanical mouse (which uses a ball) or a laser mouse (which uses a laser), an optical mouse uses a reflective LED light in order to track movement, which is why the best mousepads for ...

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 ...
