byte enc1oldPins = 0; // will hold state of pins last time encoder was read byte enc2oldPins = 0; byte enc1newPins = 0; // will hold new encoder pin reading, to be compared with last time's pin states ...

Discussion. 11 Euros for an i2c rotary encoder. Pfff. But with a RGB LED!! ... If I’m a private cheapskate I would go for a Arduino Nano that could manage 2 knobs.

Spinning the rotary encoder cycles through a menu of programs on the 16×2 LCD, ... At the heart of this build is an Arduino Pro Micro and 20 of the loudest key switches ever made — Cherry MX blues.

“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 ...

Adafruit has made an I2C interface for four rotary encoders. It comes in the form of a PCB with four footprints that accept one of the most common rotary encoder forms (Bournes PEC11 horizontal style) ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a ...

The SMA3 bearingless absolute encoder can be installed in rotary and linear applications and integrates the Multipole Pitch Technology. It is designed for linear measuring lengths up to 19.3 m (63 ...
