Electronic Dice Using Atom Matrix ESP32

In this Tutorial we are going to make an Electronic Dice that will display a different number every time you shake the Atom Matrix ESP32. The project is based on a built-in accelerometer where we detect the force of the movement.

In this tutorial we will use dots as on the real dice but if you prefer numbers you should check out this tutorial:

In Visuino, at the bottom click on the "Build" Tab, make sure the correct port is selected, then click on the "Compile/Build and Upload" button.

If you power the ATOM Matrix module and shake it the Display will start to show a random dice number from 1 to 6.
