Arduino OOP - Add Attributes to the LED Class

The video tutorial explains how to add attributes to a class in object-oriented programming, focusing on encapsulation. It discusses the use of private and public access modifiers, the concept of encapsulation, and how to define private attributes. The tutorial also covers best practices for declaring attributes, emphasizing the importance of organizing them under the private keyword.

What is the primary attribute needed for the LED class?

• Brightness

• Pin

• Color

• Voltage

What does the private keyword in a class signify?

• Attributes are accessible from anywhere

• Attributes are only accessible within the class

• Attributes are accessible from derived classes

• Attributes are accessible from outside the class

What is encapsulation in object-oriented programming?

• A technique to protect class variables and functions

• A method to override functions

• A way to inherit properties

• A process to create multiple instances

Why is it unnecessary to prefix 'LED' to the pin attribute within the LED class?

• Because it is a global variable

• Because it is a public attribute

• Because it is already within the LED class context

• Because it is a private attribute

What is the best practice for placing attributes in a class?

• Below the private keyword

• Below the public keyword

• Above the private keyword

• Above the public keyword
