Everyone has at least one extra mouse laying around; why not get some use out of it? Disassembling the mouse you can get two optical encoders plus four infrared emitter/detector pairs. Then you can ...

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 ...

Optical encoders and transducers enable users to translate information from one code to another. Optical encoders come in different varieties including rotary encoders and linear encoders. The optical ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...

Optical rotary encoders are the most widely used way to transform mechanical rotary motion into electrical signals. There are three basic configurations for optical encoders: incremental, absolute, ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...
