Add "INA219" component

  1. Add "OLED I2C" component

  1. Double click on the "DisplayOLED1" component and in the Elements window drag "Text Field" to the left side and in the properties window set "Size" to 2, "Width" to 10, and "Y" to 15

  2. In the Elements window, drag "Draw Text" to the left side and in the properties window set "Size" to 2, "Text" to mA, "X" to 100 and "Y" to 15

  3. Close the Elements window

  1. Connect "VoltageCurrentPower1" pin [Current mA] to "DisplayOLED1" > "Text Field1" pin [In]

  2. Connect "VoltageCurrentPower1" Control pin [I2C] to Arduino pin [I2C]

  3. Connect "DisplayOLED1" pin [I2C] to Arduino pin [I2C]

Step 5: Generate, Compile, and Upload the Arduino Code

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 6: Play
