Adding Additional Arduino Using I2C


Hi all - I have built a standalone payload bay using an Arduino Uno that includes four additional sensors. I would now like to integrate them into the OpenROV v2.8. I am really out of my element when it comes to the programming and electronics involved. Can someone help give me direction as to how to go about wiring this additional Arduino and modifying the code so that I can read in it’s values? My reading up on the topic leads me to believe I can use I2C to daisy chain it into the IMU’s connections but again not sure exactly how to do that. Any help is greatly appreciated. Thank you in advance!
