Complete ESP32 tutorials starting from basics to advances level. ESP32 is a famous development board for the internet of things applications. Although, other IoT development boards are also available in the market. But this board gains popularity among embedded developers and hobbyists in a short time. Because of its on-board many features such as Bluetooth, BLE, WiFi, Crypto-Engine and many others.
In this ESP32 tutorial, we will create an RGB LED controller web server. The web server will display a color spectrum that will be used to set the color of the RGB LED. The colors will primarily be divided into three: red, green, and blue. The user will pick a color from the spectrum which … Read more
In this tutorial, we will create an ESP32 MPU6050 sensor readings dashboard. The readings will consist of the current temperature in degree Celsius, rotational position (x,y,z) and acceleration (x, y, z) using server sent events (SSE). The web server will display sensor readings received by an ESP32 board connected with an MPU6050 sensor. Additionally, a … Read more
In this ESP32 web server project, we will learn how to build an ESP32 stepper motor WebSocket web server that will control the rotation of the stepper motor. This will be achieved through a user filled form we will add to the web server page. The user will specify the direction of rotation as well … Read more
In this getting started tutorial, we will learn about the 28BYJ-48 stepper motor and how to interface it with the ESP32 development board using a UNL2003 driver. The 28BYJ-48 stepper motor is inexpensive and one of the most commonly used stepper motors out there. It comes with a UL2003 motor driver attached to it that … Read more
In this useful user guide, we will show you how to enable email/password authentication for your ESP32/ESP8266 Google Firebase projects. This will make your projects more secure and even allow enabled users to access the project data through the choice of authentication method chosen. By the end of this article, you will be able to … Read more
This tutorial shows how to interface HC-SR04 or HY-SR05 Ultrasonic sensors with ESP32 for contactless distance measurement. First, we will learn to interface HC-SR04 with ESP32. After that, we will see example codes with or without the Ultrasonic sensor Arduino library. Firstly, we will see an example to control an LED with ESP32 and an … Read more
In this tutorial, we will learn to interface DHT11 and DHT22 sensors with ESP32 using Arduino IDE. We will create a DHT11/DHT22 web server with ESP32 to display temperature and relative humidity values on a Web page. In this project, we will create two types of DHT11 and DHT22 web server: #1 DHT11/DHT22 Server Sent … Read more
In this tutorial, we will learn how to perform BLE server client communication between two ESP32 boards using Bluetooth Low Energy. In other words, we will learn to exchange data between two ESP32 boards over BLE. The communication between server and client will be through BLE where one ESP32 board acts as a BLE server … Read more
In this tutorial, we will create two types of IoT based clocks such as Analog and Digital using OLED display and ESP32 and ESP8266 NodeMCU development boards. We will use the NTP server to acquire the current time and display it on the OLED for the digital clock in a 24-hour format consisting of HH:MM: … Read more
In this ESP32 web server project, we will learn how to build an ESP32 PWM WebSocket web server that will control the brightness of multiple LEDs connected to the ESP32 GPIO pins. This will be achieved through multiple HTML sliders that we will add to the web server page. The sliders will be moved to … Read more
