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
