An ATtiny804 firmware that reads three quadrature rotary encoders and exposes their positions and button states over I2C as a slave device. An interrupt output pin notifies the host of state changes ...

Welcome to the exciting world of rotary encoders! In this project, we’ll embark on a journey to interface a rotary encoder with the Altera MAX 2 CPLD, lighting up a dazzling sequence of 4 LEDs based ...

“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, and is ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

[Stephen Carey] wanted to spruce up his car with sound reactive LEDs but couldn’t quite find the right project online. Instead, he wound up assembling a custom bass reactive LED display using an ESP32 ...
