A simple game disse/roulette with Arduino and a MAX7219 8x8 led matrix. Find this and other hardware projects on Hackster.io.

It's a 5-10 minutes project ONLY!

About this Project:

In this project we will learn how to interfacing ESP8266 module with MAX7219 matrix display to scrolling text message from web user interface. We will use Arduino IDE to program ESP module in this project. I am using MajicDesigns MD_MAX72xx library for running this project, also the code is very similar to included example in the library with some improvements in web user interface html code.

The dot matrix that we’re going to use in this guide is a 8×8 matrix which means that it has 8 columns and 8 rows, so it contains a total of 64 LEDs.

The MAX7219 chip makes it easier to control the dot matrix, by just using 3 digital pins of the Arduino board.

I think the best option is to buy the dot matrix with the MAX7219 chip as a module, it will simplify the wiring. You can check the dot matrix at Maker Advisor and find the best price.

You can control more than one matrix at a time. For that you just need to connect them to each other, as they have pins in both sides to extend the dot matrix.

In our previous blog post (Tutorial…), we were playing around with a LED MATRIX <===> First Steps with the Arduino-UNO R3 | Maker, MakerED, Coding | Scrolling Text with 8×8 LED MATRIX  <===> and we will continue to use the LED MATRIX, but this time with a Wi-Fi connection. We will use the module “ESP8266” which you can purchase worldwide around as it is very popular and it costs ONLY 7.49 €.
