What You Will Need
Arduino UNO (or any other Arduino)
Max7219 Led Dot Matrix 8-digit Digital Display Control Module
Visuino program: Download Visuino
The Circuit
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]
Start Visuino, and Select the Arduino UNO Board Type
The Visuino: https://www.visuino.eu also needs to be installed. Download the 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 in Picture 2
In Visuino Add, Set & Connect Components
Add "Maxim LED Display Controller SPI MAX7219/MAX7221" component
Add "Sequence" component
Add "Text Value" component
Double click on the "Sequence1" and in the "Elements window" drag "Period" to the left side and in the properties window set "Delay" to 1000
in the "Elements window" drag another "Period" to the left side, and in the properties window, set "Delay" to 2000
in the "Elements window" drag another "Period" to the left side, and in the properties window, set "Delay" to 3000
in the "Elements window" drag another "Period" to the left side, and in the properties window, set "Delay" to 4000
Select "Sequence1" and in the properties window set "Repeat" to Tue
Double click on the "TextValue1" and in the "Elements window" drag "Set Value" to the left side and in the properties window set "Value" to HELLO
in the "Elements window" drag another "Set Value" to the left side, and in the properties window, set "Value" to HOUU
-because the LED display can not show "W" we must use 2"U U".in the "Elements window" drag another "Set Value" to the left side, and in the properties window, set "Value" to ARE
in the "Elements window" drag another "Set Value" to the left side, and in the properties window, set "Value" to YOU
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 "Elements window
Double click on the "LedController1" and in the "PixelGroups window" drag "Text Display 7 Segments" to the left side
Close the "PixelGroups window"
Connect "Sequence1 > Period1" Pin[Out] to "TextValue1 > SetValue1" pin [In]
Connect "Sequence1 > Period2" Pin[Out] to "TextValue1 > SetValue2" pin [In]
Connect "Sequence1 > Period3" Pin[Out] to "TextValue1 > SetValue3" pin [In]
Connect "Sequence1 > Period4" Pin[Out] to "TextValue1 > SetValue4" pin [In]
Connect "TextValue1" pin [Out] to "LedController1" pin [Clock]
Connect "TextValue1" pin [Out] to "LedController1" > "Text Display 7 Segments1"pin [In]
Connect "LedController1" pin Out SPI to Arduino Pin SPI [In]Connect "LedController1" pin Chip Select to Arduino Digital Pin [10]
Generate, Compile, and Upload the Arduino Code
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.
Play
If you power the Arduino module, the LED Display will start to display changing Text.
Congratulations! You have completed your project with Visuino. Also attached is the Visuino project that I created for this. You can download it and open it in Visuino: https://www.visuino.eu
