That’s the idea behind this Arduino-based measuring jig for fabricating parts for a CNC build. When it comes to building on the cheap, nobody holds a candle to [HomoFaciens].

Each encoder has 20 detents per revolution with a rotational torque of detent of 1 oz.-in. Operating life is 50,000 cycles, and the optional SPST momentary switch’s lifespan is 15,000 actuations.

Rotary encoder decode for Arduino It is amazing how many Arduino programmes for decoding rotary encoders start with something like: “I looked at all the available rotary encoder sketches and none of ...
