Taste The Code. How to Use Rotary Encoders and Interrupts With Your Arduino Projects. Posted: June 10, 2025 | Last updated: June 10, 2025. Hi, I'm Bill.

It is amazing how many Arduino programmes for decoding rotary encoders start with something like: "I looked at all the available rotary encoder sketches. About Us; Contact Us; ... // Encoder 1 pin A ...

At the heart of the device is a AD9833 waveform generator; with the Arduino, rotary encoder, ... There are several Arduino-driven DDS projects (example: the Poor Hams Scalar Network Analyser).

If you’ve been stuck on a project that uses a rotary encoder because you’ve run out of pins, this novel approach may help you get un-stuck. It’s a pretty impressive feat of circuit design to ...
