What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

Rotary encoders are pretty interesting pieces of technology. They’re a solid way to accurately measure rotation including the direction. [David] recently wrote some software to handle these input ...

[Long Haired Hacker] has undertaken a high-resolution 3D printer build. He got his hands on some motors to drive the build platform but it doesn’t have a built-in encoder. He knows that optical ...

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 quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...

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 ...
