Lesson 11 | Understanding loop() and setup() | Arduino Crash Course

This video tutorial explains the two essential functions in Arduino programming: setup and loop. Using a sub shop analogy, the instructor illustrates how setup is like preparing the shop for opening, executing tasks only once, while loop is akin to serving customers repeatedly, executing tasks continuously. The video details the syntax and purpose of each function, emphasizing their roles in structuring Arduino sketches. The tutorial concludes with a review, reinforcing the necessity of these functions in every Arduino program.

What are the two special functions used in every Arduino sketch?

What types of tasks are typically included in the setup function?

In what scenarios would you need to reset the Arduino to run the setup function again?

Describe the purpose of the setup function in an Arduino sketch.

What does the term 'void' signify when used with the setup and loop functions?

What happens to the code inside the setup function after it has been executed?

How does the loop function differ from the setup function?

Explain how the loop function operates in an Arduino program.

How can the loop function produce different results with each iteration?

Why is it important for the setup and loop functions to be present in an Arduino sketch?
