I needed a rotary encoder — I pulled a cheap one out of one of those “49 boards for Arduino” kits you see around. Not the finest encoder in the land, I’m sure, but it should do the job.

The quadrature encoder with acceleration would seem easiest, but it still needs coding. My bright (I claim…) idea is to use two potentiometers connected to two analogue arduino inputs (method below), ...

The Sno (pronounced like “snow”) board is a tiny footprint Arduino board ... there is one that will do quadrature decoding for dealing with things like shaft encoders. There are a few others ...

LS7082N1, LS7083N, LS7084N, LS7183N, and LS7184N interface incremental encoders and counting devices by converting the encoder quadrature outputs into directional up/down clocks or clock and ...

Typical encoder output, a series of quadrature signals, consists of two full square Encoders are widely used to help control machine position and speed. Typical encoder output, a series of ...

If you are a novice to rotary encoders for human-machine interface, there is a potential pit-fall. Otherwise called quadrature encoders, they deliver two-bit gray-scale binary on rotation, with the ...
