This Arduino project uses individually addressable LED strips (aka NeoPixels) with the FastLED library to make a colorful and simple timer controlled by a rotary encoder.

This timer has the same hardware structure as Timer-with-Arduino-and-rotary-encoder-1. Different soft structure. The time is displayed in the format hh mm ss. Maximum time is 99h 59m 59 s. Programming ...

But then, [crispernaki] remembered the magnetic rotary encoder demo board that was just sitting around, along with various microcontrollers and Altoids tins.

This application note demonstrates how to read data from the two-channel output of an incremental rotary encoder. Data from these two channels are based on the Gray Encoding System and can be used to ...

It looks beautiful, yes, but it’s also a great way to maintain sanity while programming and troubleshooting. Keyboard builds can look daunting, even at 40% of standard size.

LILYGO TTGO T-Encoder, a round-shaped ESP32 board with a built-in rotary encoder, has gotten a shield with a 2-key keypad based on WCH CH552 8-bit microcontroller. Launched several months ago, the ...

For example, 1024 positions (or 10-bit resolution) can be achieved with four sensors and 128 poles. 1. A magnetic rotary encoder comprises two poles and two sensors.

The addition of a small microprocessor, a rotary encoder, and a display makes a complete signal generator. What’s Under the Hood Signal generation is accomplished by direct digital synthesis (DDS). It ...
