Get started quickly with ESP32 and Firebase (Realtime Database) and program with Arduino IDE. Firebase is Google’s mobile application development platform that includes many services for managing data from web, iOS, and Android applications. The first step in the process…

Using an ESP32 board and a magnetic reed switch, you will use this project to monitor the status of a door. When the status of the door changes—from open to closed—you’ll receive an email message. The ESP32 board will be…

This tutorial shows how to use ESP32 with PIR motion sensor using interrupts and timers. In this example, the ESP32 starts a timer and turns on an LED for a specified number of seconds. The LED is automatically turned off…

Build a door status monitor using ESP32 and a magnetic reed switch. You’ll receive a Telegram Notification whenever the door changes state Using an ESP32 board and a magnetic reed switch, you will use this project to monitor the status…

Add WiFi to Arduino UNO with ESP8266 WiFi Module The ESP8266 WiFi module is a full Wi-Fi network that can be readily connected to any microcontroller-based design as a serving Wi-Fi adapter and wireless internet access interface through its simple…

In this tutorial, we’re going to show you how to control servo motor with an ESP32 Web Server. Before we build the web server, we’ll take a short look at ESP32 servo control. Parts List You will need the following…

In this article, we’ll teach you how to build an ESP32 web server that serves HTML and CSS files saved on the filesystem. We’ll generate separate HTML and CSS files rather than having to write the HTML and CSS text…

Learn how to Use ESP32 with VS Code & Platformio to Upload Files to Filesystem (SPIFFS). Instead of needing to write everything within the Arduino sketch, it may be useful to leverage the filesystem with the ESP32 to save HTML,…

The Serial Peripheral Interface Flash File System (SPIFFS) is built into the ESP32. SPIFFS is a lightweight filesystem designed for microcontrollers with flash chips linked through an SPI connection, such as the ESP32 flash memory. In this post, we’ll show…

Learn how to send email from ESP32 via SMTP server. We’ll show you how to send a simple HTML or raw text email, as well as how to send attachments like images and files (.txt). Using Arduino’s IDE, the ESP32…
