Learn how to securely store Wi-Fi credentials and other sensitive information in a separate file for your ESP32 projects (also works for other Arduino based projects). This approach eliminates the …
Learn how to configure and handle interrupts with the ESP32 board to detect and respond to changes on its input GPIOs. We’ll build a project example using a pushbutton and …
Learn how to use a PIR (Passive Infrared) Motion Sensor with the ESP32 programmed with Arduino IDE to detect motion. We’ll create a simple example to introduce you to the …
In this guide, we’ll introduce you to and explain how to use FreeRTOS semaphores with the ESP32, using the Arduino IDE. Semaphores are like signals (or flags) that allow you …
In this guide, you’ll learn how to use FreeRTOS queues for safe and efficient communication between tasks on the ESP32, using the Arduino IDE. Queues allow you to exchange data …
In this tutorial, we’ll introduce the basic concepts of FreeRTOS and show you how to use it with the ESP32 and the Arduino IDE. You’ll learn how to create single …
In this tutorial, you’ll learn how to build a web server with the ESP32 that serves HTML and CSS files stored in the LittleFS filesystem. Instead of embedding the HTML …
In this project, you’ll learn how to use the ESP-NOW communication protocol with the ESP32 CYD Board (Cheap Yellow Display) to receive and display data from multiple ESP32 sender boards. …
Learn how to program the ESP32 boards using VS Code (Microsoft Visual Studio Code) with the pioarduino IDE extension. The pioarduino IDE extension supports the latest Arduino core for the …
Learn how to use the APDS9960 sensor with the ESP32 using Arduino IDE. This sensor combines gesture detection, proximity sensing, and ambient RGB light measurement over I2C. In this guide, …
In this guide, you’ll create a Firebase Web App to control the ESP32 or ESP8266 GPIOs from anywhere. The access to the web app is protected with authentication using email …
In this guide, you’ll learn how to control the ESP32 GPIOs from anywhere using Firebase. We’ll create nodes on the Firebase Realtime Database to save the current GPIO states. Whenever …
In this project, you’ll create a Firebase Web App that displays all the sensor readings saved on the Firebase Realtime Database. We’ll create a web interface with gauges, charts, and …
