How to Use a Button with an Arduino

This video tutorial guides viewers through controlling an LED with an Arduino using a button. It covers the basics of algorithms, pseudocode, and flowcharts, and provides a step-by-step guide to building the circuit using Tinkercad. The tutorial also explains how to connect a button and write the necessary code to control the LED, including using variables and if-else statements. The video concludes with programming challenges to reinforce learning.

What steps should be taken to ensure the button is correctly placed on the breadboard?

What are the potential risks of not using a pull-down resistor in the circuit?

Explain the process of writing the code to control the LED using the button.

How can you change the LED pin in the code without affecting multiple lines?
