INA226 Overvoltage Warning Light & Sound Using Arduino

In this tutorial we will learn how to make a overvoltage warning using the INA226 module, LED and a Piezo buzzer module.

If the Voltage is below the 6V the Green LED will glow, if the Voltage is above the 6V the Red LED will glow and the piezo buzzer will beep. Voltage can be set according to your needs.

Step 1: What You Will Need

• Arduino Uno or any other Arduino board
• INA226 module More Info and here
• Jumper wires
• (Optional) Power Supply to do the test
• Visuino software: Download here

Step 2: Brought by PCBWay

Thank you PCBWay for supporting this tutorial and helping users learn more about electronics.

NEW! Now you can get Aluminum PCB & FLEX PCB in their Special Offer!

What I like about the PCBWay is that you can get 10 boards for approximately $5 which is really cost effective for professional made boards, not to mention how much time you save!

Go check them out here. They also offer a lot of other stuff in case you might need it like assembly, 3D printing, CNC machining and a lot more.

Step 3: The Circuit

Step 4: 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 5: In Visuino Add Components

Step 6: In Visuino Set Components

• Select “DigitalMultiSource1” and in the properties window set “Output pins” to 3
• Double click on the “PlayFrequency1” and in the Elements window drag “Play Tone State” to the Left side and in the properties window set “Frequency (Hz)” to 20
• Close the Elements window

• Select “VoltageCurrentPower1” and in the properties window expand “Alerts“>:Limit” and set “Above” to True
• Now expand “Alerts“>:Limit“>”Bus Voltage” and set “Value (V)/(A)/(W)” to 6 (or any other Voltage value that you need)

Step 7: In Visuino Connect Components

• Connect “VoltageCurrentPower1” pin I2C (Control) to Arduino Pin I2C (In)
• Connect “VoltageCurrentPower1” pin Limit (Out) to “DigitalMultiSource1” pin (In)
• Connect “DigitalMultiSource1” pin (0) to Arduino digital pin (2)
• Connect “DigitalMultiSource1” pin (1) to “Inverter1” pin (In)
• Connect “Inverter1” pin (Out) to Arduino digital pin (3)
• Connect “DigitalMultiSource1” pin (3) to “PlayFrequency1” > “Play Tone State1” pin (In)
• Connect “PlayFrequency1” pin (Out) to Arduino digital pin (4)

Step 8: 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.
