Creactesp::ISREvent	Event that is triggered on an input pin change
Creactesp::TimedEvent	TimedEvents are called based on elapsing of time
Creactesp::DelayEvent	Event that is triggered after a certain time delay
Creactesp::RepeatEvent	Event that is triggered repeatedly
Creactesp::UntimedEvent	Events that are triggered based on something else than time
Creactesp::StreamEvent	Event that is triggered when there is input available at the given Arduino Stream
Creactesp::TickEvent	Event that is triggered unconditionally at each execution loop
