## 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.
