Custom-made self-contained DC power meter

In this video, I show you my new device which is a DC power meter. This specific power meter is capable of measuring up to 85 V thanks to the INA238 chip and up to 15 A (20 A for shorter periods) thanks to the unique 2 milliOhm, 5 W current sensing shunt resistor.

Interesting project. A question. When it is self powered does the meter count its self consumption? And a second one. Will this code run on a Arduino?

[@CuriousScientist]

Hi! No, the supply line of the meter is connected to the +IN pin, _before_ the current passes through the shunt. Therefore the consumption of the meter itself is not included in the consumption. My plan was to measure the current that goes through the load, so I connected it this way. As for the second question. I don't know if you have missed it, but there is a nearly 30-minute part in the video where I am rambling about the code, written in Arduino IDE. I hope this answers your question...
