Story

Step 1: What You Will Need

  • Arduino UNO or any other Arduino board
  • Breadboard
  • OLED Display
  • INA219 DC Current Sensor
  • Jumper wires
  • Power Supply
  • Some load like a light bulb or DC motor
  • Visuino software: Download here

Step 2: The Circuit

  • Connect INA219 pin [SCL] to Arduino pin [SCL]
  • Connect INA219 pin [SDA] to Arduino pin [SDA]
  • Connect INA219 pin [VCC] to Arduino pin [5v]
  • Connect INA219 pin [GND] to Arduino pin [GND]
  • Connect OLED Display pin [SCL] to Arduino pin [SCL]
  • Connect OLED Display pin [SDA] to Arduino pin [SDA]
  • Connect OLED Display pin [VCC] to Arduino pin [5v]
  • Connect OLED Display pin [GND] to Arduino pin [GND]
  • Connect Power Supply (+) to INA219 pin [Vin -]
  • Connect Light Bulb (+) to INA219 pin [Vin +]
  • Connect Light Bulb (-) to Connect Power Supply (-)

Step 3: Start Visuino, and Select the Arduino UNO Board Type

The Visuino: https://www.visuino.com also needs to be installed. Download Free version or register for a Free Trial.

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 & Connect Components

  • Add "INA219" component
  • Add "OLED I2C" component
  • 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
  • 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
  • Close the Elements window
  • Connect "VoltageCurrentPower1" pin [Current mA] to "DisplayOLED1" > "Text Field1" pin [In]
  • Connect "VoltageCurrentPower1" Control pin [I2C] to Arduino pin [I2C]
  • Connect "DisplayOLED1" pin [I2C] to Arduino pin [I2C]

Step 5: 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

Congratulations! You have completed your project with Visuino. Also attached is the Visuino project, that I created for this Instructable, you can download it and open it in Visuino: https://www.visuino.com
