Hi everyone, our team tried searching, but could not find anything concerning how to wire the four pins on i2c to an arduino uno, can anyone help?

Thanks!

Pin A4 on the Arduino connects to SDA and A5 connects to SDL. I don't think that the other pins need to be connected given that the Arduino has its own power source.

The I2C port and the Arduino Uno will need a common ground as well.
