MyRobotLab Part 15, the AdafruitIna219 Service

In this 15th video in the series, we look at the AdafruitIna219 Service
The INA219 chip is a DC power sensing chip.
It works by measuring the voltage of the supply to ground, and then the voltage of a shunt resistor to ground.
Subtracting the latter from the former give the voltage drop across the shunt resistor.
Knowing the value of the shunt resistor, allows us to calculate the current flowing through the resistor.
Knowing the current flowing and the voltage across the load, allows us to calculate the power being used as well :-)

This install is using a Windows 10 Computer and the Arduino Nano.
My load is a servo being powered by a 6V battery pack.
