Working Principle: The ESP32 microcontroller collects data and sends it to a PHP API hosted on a local server using XAMPP. The API then communicates with a MySQL database to store or retrieve data ...

In the previous project update, you learned about enhancements to the ESP32 Energy Meter’s schematic design and PCB. This article focuses on the practical implementation and integration of the new ...

This project demonstrates controlling a TFT display via WiFi connection. The goal is to properly wire the circuit and program the Wemos D1 R32 microcontroller with ESP32 chip. The project includes a ...

Waveshare ESP32-P4-NANO is the first third-party ESP32-P4 RISC-V board we’ve seen and it follows the launch of the Espressif Systems’ ESP32-P4-Function-EV-Board devkit introduced this summer. While ...

In a recent article in Elektor magazine, [Clemens Valens] describes the construction and software for an ESP32 walkie-talkie system that uses ESP-NOW for the wireless connection between units, along ...

We just got our hands on some engineering pre-samples of the ESP32-C3 chip and modules, and there’s a lot to like about this chip. The question is what should you compare this to; is it more an ESP32 ...

In this tutorial, we will learn how to install multiple versions of the ESP32 board package in the Arduino IDE. Once set up, you’ll have the option to choose a specific version of the ESP32 package ...

ESP32 microcontrollers, known for their versatility in IoT and smart home projects, also support digital audio via their I2S interface. In the first part of this series, we explore an audio-focused ...
