Arduino Display Text on MAX7219 8-digit LED Display

In this tutorial we will learn how to display a Simple text on the MAX7219 8-digit Digital LED Display using Visuino.

Watch the video.

• Arduino UNO (or any other Arduino)
• Jumper wires
• Max7219 Led Dot Matrix 8-digit Digital Display Control Module
• Visuino program: Download Visuino

• Connect LED module pin[VCC] to Arduino pin[5V]
• Connect LED module pin[GND] to Arduino pin[GND]
• Connect LED module pin[DIN] to Arduino digital pin[11]
• Connect LED module pin[CS] to Arduino digital pin[10]
• Connect LED module pin[CLK] to Arduino digital pin[13]

The Visuino: https://www.visuino.eu also needs to be installed. Download Free version or register for a Free Trial.

Start Visuino as shown in the first picture Click on the "Tools" button on the Arduino component (Picture 1) in Visuino When the dialog appears, select "Arduino UNO" as shown on Picture 2

• Add "Maxim LED Display Controller SPI MAX7219/MAX7221" component
• Doble click on the "LedController1" and in the "PixelGroups window" drag "Text Display 7 Segments" to the left side
  And in the properties window set Initial Value to: Arduino!
  
  Note: Text on this Display is limited to a certain characters, so play with it to see what kind of words you can display.
  
• Close the "PixelGroups window"

• Connect "LedController1" pin Out SPI to Arduino Pin SPI [In]
• Connect "LedController1" pin Chip Select to Arduino Digital Pin [10]

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 Arduino module, the LED Display will start to display a Text.

Congratulations! You have completed your project with Visuino. Also attached is the Visuino project, that I created for this Instructable, you can download it and open it in Visuino: https://www.visuino.eu
