A simple “On-Off” state machine

Here is a simple state machine that includes a few of the concepts.

From this drawing, we can see that

• This machine has two states, On and Off
• it transitions between them whenever it gets the flick event (that’s the two arrows between the states)
• The “on” state has some actions that happens when it enters or exits that state.

The machine basically functions as an on-off switch which turns a light on or off whenever it gets the “flick” event
