I am new to the use of Arduino in general, and to the INA226 Module for power metering.
I first got everything set up WITHOUT anything plugged to the INA226 module metering pins (V+, ISens+, Isens-, V- not connected to any power source) and running a sample code that gets data being read by the INA226, of course, all values return 0, but at least I know the program runs and the arduino can connect to the INA226. Now, the problem comes when I try to get some reading such as 5V or even 3.3V from the Arduino pins.
I connected the circuit as follows:
(I noticed that I wrote A6 instead of A4, sorry about that)
But when I do this, there is no reading at all from the serial console. I tried connecting the V+ and Isens+ directly to the 5V pin leaving everything else as shown in the diagram, but the Arduino board doesn't even turn on.
I tried referencing other sources, but their tests use external power supplies or other equipment I don't have.
I would be really thankful if someone could lend me a hand here or help me understand why am I having this problem and how can I make it read something basic such as 5V or 3.3V directly from the Arduino board.
