How to Make One Button Have the Functionality of Two or More with Arduino

This tutorial teaches how to use an Arduino to make a single button perform multiple functions. It covers the materials needed, circuit setup, and code explanation. The tutorial demonstrates how to track button press duration to trigger different LED lights, using a while loop and if-else statements. It concludes with a demonstration of the code in action.

What components are needed to set up the circuit for using a single button for multiple functions?

Explain how the press length variable is used in the code.

What are the two options defined for the button press duration, and how are they used?

How can additional options be added to the button functionality in the code?

What is the purpose of using an input pull-up for the button pin?

Describe the process of how the button press duration is measured in the loop.

Explain the role of the while loop in capturing the button press duration.

How does the code determine which LED to illuminate based on the button press duration?

What happens when the button is pressed for less than 100 milliseconds?

What is the significance of resetting the press length variable to zero after each button press?
