Add Methods to Init and Toggle Between the LEDs

The video tutorial covers the process of initializing components for a traffic light system, creating methods to control LED states, and implementing an init method to streamline the setup. It explains how to manage LED states with delays and tests the functionality of the traffic light class. The tutorial emphasizes abstraction and efficient code management, resulting in a simplified main file.

What is the primary purpose of creating methods within the traffic light class?

• To store data in a database

• To manage network connections

• To control LED states conveniently

• To handle user input

Why is a delay added after initializing the button in the init method?

• To save power

• To ensure correct data reading

• To improve performance

• To synchronize with other components

What is the default state of the traffic light when initialized?

• All LEDs off

• Red LED on

• Yellow LED on

• Green LED on

Which method is called to initialize all components in the traffic light system?

• begin()

• start()

• init()

• setup()

What does the 'red' method in the traffic light class do?

• Turns off all LEDs

• Turns on the green LED

• Turns on the red LED

• Turns on the yellow LED

What is the benefit of using abstraction in the traffic light class?

• It makes the code more complex

• It increases the number of methods needed

• It allows direct hardware manipulation

• It simplifies LED state management

How does the traffic light class simplify the main file?

• By increasing the file size

• By reducing the number of lines needed for initialization

• By adding more complex logic

• By requiring more manual input
