In this tutorial we will learn how to scroll the text on the Arduino UNO R4 display using Visuino.

Watch the video!

What You Will Need

Arduino UNO R4
Visuino program: Download Visuino

Start Visuino, and Select the Arduino UNO R4 WiFi Board Type

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 R4 WiFi" as shown on Picture 2

In Visuino Add Components

Add "Clock Generator" component
Add "Up/Down Counter" component
Add "Integer Multi Source" component

In Visuino Set Components

Select ArduinoUNO R4 WiFi board and in the properties window expand Modules>Display and select Elements and click on the 3 dots button, in the Elements window drag "Draw Text" to the left side and in the properties window select "Text" and type HELLO WORLD and select "X" and click on the pin icon and select "Integer SinkPin", also set "Wrap" to False

Select "ClockGenerator1" and in the properties window set "Frequency" to 5, this will be the speed of the scrolling text, you can adjust this value according to your needs

Select "UpDownCounter1" and in the properties window set "Initial Value" to 13, this means that we will set the text out of visibility on start
Select "UpDownCounter1" and in the properties window set "Max">"Value" to 13, this means that when the text is scrolled it will be placed again out of visibility
Select "UpDownCounter1" and in the properties window set "Min">"Value" to -70, this will be the length of the text, experiment with the number according to your text

In Visuino Connect Components

Connect "ClockGenerator1" pin [Out] to "UpDownCounter1" pin [Down]
Connect "UpDownCounter1" pin [Out] to "MultiSource1" pin [In]
Connect "MultiSource1" pin [1] to ArduinoUNO R4 WiFi > Display > "Draw Text1" pin [X]
Connect "MultiSource1" pin [1] to ArduinoUNO R4 WiFi > Display > "Draw Text1" pin [Clock]

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 LEDs on the Arduino Display will start to scroll the text.
