States diagram

Every FSM can be drawn as a state diagram. Each state will be contained in a box with arrows going from one state to another representing the transitions.

We will go through the same examples that we saw before and learn how we can create the diagrams step by step.

Turnstile

In order to create the diagram that belongs to the turnstile FSM, we need to go through the following steps:

1. First of all, we have to write down the states, as follows:

2. Next, we have to draw the transition arrow from one state to the other state that it will transition to. In this case, we have two transitions that interact in a cyclical way, as shown in the following diagram:

That's it. By drawing a diagram, it is simpler to...
