What are state machines in Arduino programming?

State machines are models of computation that can be used to design the behavior of systems. In Arduino programming, they help manage different states of a device, like turning on/off LEDs based on user input.

Can you give me an example of a state machine in Arduino?

Sure! A simple example is a traffic light system where the states are 'Red', 'Green', and 'Yellow'. The Arduino can switch between these states based on timers.

How do I implement a state machine in my Arduino code?

You can implement a state machine using a switch-case structure in your code. Define your states as constants and use a loop to check the current state and transition based on conditions.

Are there libraries available for state machines in Arduino?

Yes, there are several libraries like 'StateMachine' and 'Automaton' that can simplify the implementation of state machines in your Arduino projects.
