At the heart of the device is a AD9833 waveform generator; with the Arduino, rotary encoder, and 16×2 LCD providing an interface to control it over SPI.

It can be programed either using ST-LINK/V2 or Arduino IDE, and is open source & open hardware. This rotary encoder is suitable for integration into projects as a unique user interface, or can be ...

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 ...

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.
