Create the PushButton Class cpp File - Implementation

The video tutorial covers the process of including header files in a C program, implementing methods, and writing logic for a class constructor. It explains how to handle pin attributes and initialize input modes, particularly focusing on managing floating states using pull-up resistors. The tutorial also demonstrates how to read digital inputs and save the state within a class, ensuring that the state can be accessed by other functions.

What is the significance of the input pull-up resistor in the hardware setup?

How does the 'readState' function contribute to the functionality of the class?
