We build this practical project step by step and you can download all the codes for each chapter. Frustration–free development is guaranteed!
In this video course you will learn how to control a 8×32 LED matrix (or a MAX72xx module). We use the MD Parola library for this project. With this library we can control the text in many different ways. With this library we have the possibility to implement different ticker settings easily and fast. A text can slide in from one side and stop in the middle of the matrix for a certain time. The duration of the ticker can be adjusted and also the speed and brightness of the ticker can be easily adjusted.
We will also insert dot graphics that will make the text disappear as soon as the graphic slides over the text.
We will create a website in the course using a local web server running on the ESP32/8266. The web server will be configured in such a way that you can access the created (also in this course) website using a fixed IP address. On the website there is an input field where you can enter text. Using jQuery we send a GET request to the Arduino, which evaluates the content and displays it on the LED matrix. This way you can individually control the text via the web server.
