The device includes the connection between an Arduino microcontroller and an optical mouse sensor to provide help in reading the movements from horizontal and vertical directions. The Arduino board ...

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 ...

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 ...

We just wrapped up the Human Computer Interface challenge in this year’s Hackaday Prize, and with that comes a bevy of interesting new designs for mice and keyboards that push the envelope of what you ...

Tiny MP3 players are great, but the tiny means of navigation they often employ can be a big pain in the ass. The Minput project explores the possibility of using optical sensors to let those devices ...
