Learn how LED matrix works, how to connect LED matrix to ESP32, and how to program ESP32 step by step. Detailed instructions, code, wiring diagram, video tutorial, and line-by-line code explanation are provided to help you quickly get started with ESP32.

Through this tutorial, we will familiarize you with the MAX7219 dot matrix display and program ESP32 to show various demonstrations of displaying texts. These will include displaying and scrolling text on the dot matrix.

The design was made to be easy to assemble, sturdy, and compatible with both ESP32. The frame is made up of: A main box to insert the LED matrix. A locking grid to secure the matrix in place without crushing the small capacitors next to the LEDs. A 169x169 mm sheet of printer paper to diffuse the light.

The PIXELIX firmware is for ESP32 boards that controls a RGB LED matrix. It can be used to display text and animations. Supports 32x8 LED matrix size out of the box. Its possible to cascade another matrix to have a longer display. Can display static or scrolling text, as well as static (BMP and GIF) or animated icons (GIF).

In this tutorial, we will learn how to control LED matrix signboard via web interface using ESP32. In detail, we will program ESP32 to become a web server that does the following: Returns a web interface to users when receiving a request from a web browser. Displays the messages on the LED matrix once receiving the message.
