I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...

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 ...

Rotary encoders are electromechanical devices used for sensing in myriad applications—on motors paired with drives and automated machinery for everything from consumer electronics, elevators, and ...
