The difference between a half step or half step Rotary Encoder type is how the data signals of the two pins are generated. It depends on the mechanical construction of the notches and contacts inside ...

rot_btn_i2c is a ESP32 IDF component to read and decode a mechanical rotary encoder and up to 14 buttons connected to the ESP32 by a TCA9555 port expander. It uses the RiskV ULP of the ESP32-S3 and ...

The 8051 was an 8-bit Harvard-architecture microcontroller first put out by Intel in 1980.  They’ve since discontinued that ...

In this video, I'm exploring the use of Mini PIR Sensors with ESP32 with both Arduino-based projects as well as making a movement sensor for Home Assistant by using ESPHome. The sensor is quite ...

In this video I'm building an Arduino Heart Rate Monitor that is housed in a toy handle in the style of the Star Trek Tricoder. The device uses the PulseSensor with an Arduino Pro Mini and an OLED ...

Today I learned that WiFi and Bluetooth LE could NOT be used simultaneously on Arduino boards featuring the ESP32-based u-blox NINA-W102 wireless module, ...

At embedded world, on the DigiKey booth, Lucy Barnard speaks with Marta Barbero at Arduino, about the new Arduino product announcement.

There’s a meme which may have a basis in truth, of a teenager left clueless when presented with a rotary telephone. The dial, in reality a mechanical pulse chain generator, was once ...

Abstract: This paper presents a precision capacitive rotary encoder that integrates a shared charge amplifier, and a multi-stage offset calibration scheme. Recently, capacitive encoders have gained ...

Lika Electronic's EHO36, EHM36, and EHO37C rotary absolute encoders are built in a very compact and rugged 36-mm housing and feature 6-mm solid and blind hollow shafts. Their small footprint and ...
