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 ...

Use this circuit to implement those knobs you see on oscilloscopes, radios and other devices. Turning the knob clockwise generates a series of low-going pulses from the COUNT-UP output while turning ...

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 ...
