1 / 2
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
Step 4: In Visuino Add & Set Components1 / 10
- Add "Debounce Button" component
- Add "Toggle(T) Flip-Flop" component
- Add "Digital Multi Source" component
- Add "Detect Edge" component
- Add "OLED I2C" component
- Select "DigitalMultiSource1" and in the properties window set "Output Pins" to 3
- Select "DetectEdge1" and in the properties window set "Rising" to False
- Double click on the "DisplayOLED1" and in the "Elements" window:
- drag "Fill Screen" to the left side
- drag "Draw Text" to the left side and set in the properties window set "Size" to 3, "Text" to Display (Or any other text) and "Y" to 20
- drag another "Draw Text" to the left side and set in the properties window set "Color" to tmcBlack, "Fill Color" to tmcWhite, "Size" to 3, "Text" to Display (Or any other text) and "Y" to 2
- Close the "Elements" window
- Connect Arduino digital pin [7] to "Button1" pin [In]
- Connect "Button1" pin [Out] to "TFlipFlop1" pin [Clock]
- Connect "TFlipFlop1 pin [Out] to "DigitalMultiSource1" pin [In]
- Connect "DigitalMultiSource1" pin [0] to "DisplayOLED1" > "Fill Screen1" pin [Clock]
- Connect "DigitalMultiSource1" pin [1] to "DisplayOLED1" > "Draw Text1" pin [Clock]
- Connect "DigitalMultiSource1" pin [2] to "DetectEdge1" pin [In]
- Connect "DetectEdge1" pin [Out] to "DisplayOLED1" > "Draw Text2" pin [Clock]
- Connect "DisplayOLED1" I2C pin [Out] to Arduino board I2C pin [In]
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: PlayIf you power the Arduino module, The OLED Display will show the Text, if you press the button the text color will Invert.
Congratulations! You have completed your project with Visuino. Also attached is the Visuino project, that I created for this tutorial, you can download it and open it in Visuino: https://www.visuino.eu
