Reading INA 219 sensor through Arduino

Hey guys,

I'm trying to read data from my INA 219 current sensor, through ARDUINO UNO.77 I'm new to I2C communication so I'm getting hard time getting significant data out of it. I guess my issue is with the sensor itself and not so much the programming part. Anybody with experience in INA219 who can give me an hint of what I should do. Maybe there's a couple of configurations I'm skipping. Thanks in advance!

You need to send and receive 'uint16' not uint8. INA has 16 bit communication interface.

I make such a result according to your program code.

I would like to ask how to display the current value

Thanks you!
