These interfaces add a physical ‘clicky’ knob to the front of a display without traditional rotary encoder electronics. Instead, a passive rotatable clicky knob is simply stuck to the front of the ...

The encoder design [Jan] settled on was to make a simple adjustable plate capacitor using PCB elements with transparent tape as the dielectric material. This was used as the timing element for a ...

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 ...
