arduino basics handling multiple states

Follow these steps to connect two Arduino UNOs using I2C:
Follow these steps to connect two Arduino UNOs using I2C:
1Connect pins A4 and A5 on one Arduino to the same pins on the other one.
2) The GND line has to be common for both Arduinos.
Connect it with a jumper.

What is a state machine in Arduino?

A state machine is implemented by defining state logic as a function in your sketch.
Transitions are implemented as functions returning a boolean value and a next state number.
