Scrolling Text on Arduino UNO R4 WiFi Using Visuino

Step 1: What You Will Need

• Arduino UNO R4
• Visuino program: Download Visuino

Step 2: 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

Step 3: In Visuino Add Components

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

Step 4: 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
• Close the Elements window
• 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

Step 5: 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]

Step 6: 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.

Step 7: Play

If you power the Arduino module the LEDs on the Arduino Display will start to scroll the text.
