The [switch-case](https://www.arduino.cc/reference/en/language/structure/control-structure/switchcase/) structure, commonly used in [FiniteStateMachines](https://forum.arduino.cc/t/yet-another-finite-state-machine-introduction/1198997) is a good alternative to of complicated nests of if statements.
