This project demonstrates a simple dashboard for visualizing sensor data from an ESP32 microcontroller via MQTT. The ESP32 publishes simulated sensor readings (temperature and humidity) to an MQTT ...

One of features of ESP32 that has been intriguing me since its release back in September 2016 was low noise amplifier (LNA). Some time later, in May 2017, the LNA has been officially documented in ...

Accessing my computers remotely has always been a challenge since I don’t leave them running all the time. After setting up Wake-on-LAN on my home server, I wanted to remotely wake up and access my ...

Ever wondered if a small, low-cost board like the ESP32-CAM can actually recognise objects or even identify Indian currency notes? In this project, the answer is a clear yes. We combine the ESP32-CAM ...

Designed by Namnam in Vietnam, the ESP32 Modbus gateway is built to communicate with PLCs and industrial sensors over Modbus RTU (RS-485) or Modbus TCP/IP (Ethernet/Wi-Fi). Designed for use in farms, ...

FlashESP is a web-based tool allowing the development of Arduino sketches and firmware flashing for ESP32 and ESP8266 hardware platforms. I initially thought it was similar to ESP Web Tools for ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...

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 ...
