In this post we show how to show text with a 8×8 LEDs matrix max7219 to use with your DYOR robot and Facilino.

Facilino has a simple instruction to show some text with a 8×8 LEDs matrix max7219. This instruction requires Facilino’s license.

The aim is to show the sentence “DYOR is cool!”.

Circuit

Here we show the proposed circuit so that the LEDs matrix is connected to pins D10, D11 y D12 de Arduino Nano. In particular, CS pin is connected to D10, DIN is connected to D12 and CLK is connected to D11.

Facilino

Here you can find the solution of the example:

Here we show the expected result:
