Tutorial: How to Use INA226

The INA226 module is ideal for measuring current and voltage in electronic circuits. It is useful for makers and designers who require precision in current measurements.

What you need

• Arduino
• I2C Cable
• Pull-up Resistor
• Multimeter

Steps

1. 1. Installation: Download and install the latest version of Arduino IDE.
2. 2. Connection: Connect the INA226 module to your Arduino via the I2C bus.
3. 3. Configuration: Add the code to configure the module.
4. 4. Test: Use a multimeter to check the current and voltage.
5. 5. Script: Load the example sketch provided.
6. 6. Verification: Check that the current and voltage values are correct.
7. 7. Debugging: If the values are not correct, check the datasheet.
8. 8. Usage: Use the module to measure currents and voltages in circuits.

Example code

```void loop() { Wire.beginTransmission(0x40); Wire.write(0x00); Wire.endTransmission(); delay(100); Wire.requestFrom(0x40, 2); if (Wire.available()) { int current = Wire.read() * 256 + Wire.read(); Serial.print("Corrente: "); Serial.print(current); Serial.println(" mA"); }}```

Mini project

Build a power supply circuit with a DC-DC converter and measure the output current.

Common mistakes

• Connect the INA226 module without pull-up resistor.
• Omit initial configuration.
• Do not use a multimeter to check values before uploading the sketch.
• Do not check current and voltage values on the datasheet.

Recommended accessories

• DC-DC Converter
• 10kΩ pull-up resistor
• I2C cable
• Multimeter

Frequently asked questions

What is the difference between current and voltage?
Current is the flow of electric charge, voltage is the potential difference between two points.

Can I measure currents above 36V?
No, the module only supports voltages up to 36V.

How can I verify the correctness of the values?
Use a multimeter to compare the values measured by the module.

Does the module support negative currents?
Yes, the module supports bidirectional currents.
