Add a State Machine Inside the Class

The video tutorial explains how to manage the state of a traffic light using a state machine. It covers the creation of an update method to handle state transitions, the use of enums to define states, and the implementation of a state machine using switch cases. The tutorial also demonstrates how to make an LED blink without blocking the program, highlighting the importance of abstracting functionalities into classes for more complex operations.

What is the primary purpose of using a state machine in the traffic light class?

• To calculate the energy consumption of the traffic light

• To control the brightness of the LEDs

• To manage the different states of the traffic light

• To handle the physical construction of the traffic light

Which method is used to implement the state machine in the traffic light class?

• update

• init

• start

• reset

What is the role of the 'update' method in the traffic light class?

• To initialize the traffic light

• To change the color of the LEDs

• To handle state transitions quickly

• To turn off the traffic light

Why are enums used in the traffic light class?

• To calculate the duration of each state

• To manage different states within a switch statement

• To define the physical layout of the traffic light

• To store the color values of the LEDs

What is the advantage of using enums over constants in a switch statement?

• Enums are faster to execute

• Enums provide better readability and context within a class

• Enums are easier to debug

• Enums require less memory

What action is performed when the traffic light is in the 'blink green' state?

• The yellow LED blinks

• The red LED is turned on

• The green LED blinks at a set rate

• The green LED is turned off

Why is it important to initialize the state before entering the state machine?

• To ensure the traffic light starts in a known state

• To save power

• To prevent the LEDs from overheating

• To reduce the complexity of the code
