Arduino Momentary Push Button and Simple Circuit drawing

The video tutorial explains the concept of momentary push buttons, how they function in a circuit, and their physical structure, including the prongs and sides. It further details setting up a button circuit using an Arduino, emphasizing the role of pull-down resistors to manage voltage levels and ensure proper circuit operation.

Summarize the process of setting up a button circuit with an Arduino as described in the text.

How does pressing the button affect the voltage at pin 5?

What is meant by the term 'floating' in relation to pin 5?
