INA3221 3 Channel Current sensor with I2C

/*
The INA3221 is a 3 channel current sensor with I2C interface. Here's an example code in Arduino that reads the current from the sensor:

Note: This code assumes that the INA3221 sensor is connected to the I2C bus of the Arduino board. If you're using a different interface, you'll need to modify the Wire library calls accordingly. Also, the calibration values used in the code are for the default configuration of the INA3221, which has a maximum voltage of 32V and maximum current of 2A. If you're using a different configuration, you'll need to set the calibration values accordingly using the appropriate setCalibration method. Finally, note that the INA3221 has a maximum input voltage of 36V, so be sure to use appropriate voltage dividers or other means to ensure that the voltage applied to the sensor does not exceed this limit.
