I will not go into greater detail of the code behind the rotary encoder + arduino experiment, as featured articles and great tutorials are available all over the web. Lab Note: RT & Arduino experiment ...

It is based on some assembler code I wrote for a PIC years ago, and relies on polling the current state of the two input pins from a rotary encoder, and comparing these two binary bits with their ...

Arduino’s GND rail is common to the rotary encoder’s common pin (C) and the cathode of LED 3, while the 5V rail is used to pull-up the data pins (A &B). Arduino’s D9 pin controls LED3. During power on ...

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.

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.

“Roendi (Rotary Encoder with Display) features a STM32L433 MCU, 1.28″ TFT round display and a Alps Alpine 15Pulses/30Detent encoder. It can be programed either using ST-LINK/V2 or Arduino IDE ...
