Add Attributes to the LED Class

The video tutorial explains how to add attributes to a class in object-oriented programming, focusing on the use of access modifiers like private and public. It highlights the concept of encapsulation, which protects class variables and functions from being modified externally. The tutorial demonstrates defining a private attribute within a class and emphasizes best practices for organizing class attributes.

What is the primary attribute needed for the LED class?

• Color

• Pin

• Brightness

• 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 only by subclasses

• Attributes are accessible only by external functions

What is encapsulation in object-oriented programming?

• Using only global variables in a class

• Making all class methods public

• Allowing unrestricted access to class attributes

• Hiding the implementation details of a class

What data type is used for the pin attribute in the LED class?

• Float

• Integer

• String

• Byte

Where should attributes be placed within a class for best practice?

• At the bottom of the class

• At the top of the class

• Below the private keyword

• Above the public keyword
