Bojan Jurca’s open-source Arduino sketch "Esp32_oscilloscope," transforms any ESP32 board to function as a web-based oscilloscope accessible over WiFi. While the Scoppy project demonstrated the ...

The analog input of an Espressif ESP32 doesn't seem very reactive in the very first part of its allowed range, with a lack of response, and a non-linearity in the whole range, consequently. The aim of ...

This project provides a complete system for reading data from a 16-channel analog sensor using a compatible microcontroller (like ESP32, Arduino, STM32, etc.), sending the data to a Node.js backend, ...

This library provides an interface for the Gravity: 7/24 Industrial Analog pH Meter Kit V2 specifically tailored for the ESP32 platform. This library adapts the functionality of the original Gravity ...

We previously noted the ESP32 Arduino Core 3.0.0 Alpha release added support for ESP32-C6 and ESP32-H2 among other changes. The good news is that Arduino ESP32 Core 3.0.0 is now considered stable, and ...

Some of the newer Espressif Systems wireless SoCs such as the ESP32-H2 and ESP32-C6 support Zigbee through their built-in 802.15.4 radio. It’s been working since the release of the ESP-IDF 5.1 ...

Water is one of our most precious resources, vital for all forms of life on Earth. Despite its importance, water wastage is a significant issue globally, contributing to water scarcity and ...

Little Bird Electronics posted an article about using an analog voltage reference with Arduino. This is a tool available when using an analog-to-digital converter. By setting up either an internal or ...

When it comes to educational electronic projects, it’s hard to go past building a clock. You learn tons about everything from circuit concepts and assembly skills to insights about the very nature of ...
