In this tutorial, we are going to turn ON or OFF the OLED display using a button & Arduino.
Watch the video!
What You Will Need
Arduino UNO (or any other Arduino or ESP32)
Visuino program: Download Visuino
The Circuit
Connect OLED Display pin [SCL] to Arduino pin [SCL]
Connect OLED Display pin [SDA] to Arduino pin [SDA]
Connect OLED Display pin [VCC] to the breadboard positive pin [5V]
Connect OLED Display pin [GND] to the breadboard pin [GND]
Connect Arduino Digital pin [4] to the Resistor and button
Connect the other side of the resistor to the breadboard pin [GND]
Connect the other pin of the button to the breadboard positive pin [5V]
Start Visuino, and Select the Arduino UNO 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" as shown in Picture 2
In Visuino, Add Components
Add "Debounce Button" component
Add "Toggle(T) Flip-Flop" component
Add "OLED I2C" component
In Visuino Set Components
Select "DisplayOLED1" and in the properties window select "Power On" and click on the pin icon and select "Boolean SinkPin"
Double click on the "DisplayOLED1" and in the "Elements" window, drag "Draw Text" to the left, and in the properties window, set "Text" to ARDUINO and "Size" to 3
Close the "Elements" window
Select "TFlipFlop1 and in the properties window set "Initial Value" to False
In Visuino Connect Components
Connect Arduino digital pin[4] to "Button1" pin [In]
Connect "Button1" pin [Out] to "TFlipFlop1" pin [Clock]
Connect "TFlipFlop1" pin [Out] to "DisplayOLED1" pin [Power On]
Connect "DisplayOLED1" pin I2C [Out] to Arduino pin I2C [In]
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 display will show the text; if you press the button, the display will turn on or off.
