Am trying to use I2C on a genuine Arduino Micro, using pin D2 for SDA and pin D3 for SCL, as shown in the pinout diagram. Question: do I also need to define those pins in code? The SDA and SCL pins on the UNOs that I tried do not need to be defined, but not sure about Micros. Thanks!

Solved. found out they do not need to be defined on Micro either.
