I'm relative new to electrical engineering, so this might be a obvious question. I'm trying to allow two arduinos to communicate with one i2c sensor. One of the arduinos is deeply integrated within the system and on the same i2c bus as the sensor, while the other one is just a standalone arduino only used occasionally for debugging and data collection and is not on the same i2c bus.
I guess I'm looking for a IC that can switch between the two devices so that it can isolate the sensor and form a i2c bus with the second arduino when needed, and switch back to the other i2c bus otherwise.
Thanks!
