+## Turnstile
+
+An example of a simple mechanism that can be modeled by a state machine is a
+turnstile. A turnstile, used to control access to subways and amusement park
+rides, is a gate with three rotating arms at waist height, one across the
+entryway. Initially the arms are locked, blocking the entry, preventing patrons
+from passing through. Depositing a coin or token in a slot on the turnstile
+unlocks the arms, allowing a single customer to push through. After the customer
+passes through, the arms are locked again until another coin is inserted.
+

+deno run ./examples/turnstile.ts
