The Complete Beginners Guide to Arduino - 2021 - The Anatomy of an Arduino Program

The video tutorial explains the setup and loop functions in Arduino programming. The setup function is used for initial configurations and runs once, while the loop function contains the main code that repeats continuously. It emphasizes the importance of placing global variables and constants at the top of the code and organizing functions for better readability. The use of comments is recommended to identify function blocks easily.

What is the primary purpose of the setup function in an Arduino program?

• To initialize hardware and prepare the environment

• To include external libraries

• To run the main code repeatedly

• To define global variables

Which function in an Arduino program runs continuously as long as the device is powered on?

• Setup function

• Main function

• Initialize function

• Loop function

Where should global variables and constants be placed in an Arduino program?

• Inside the loop function

• At the bottom of the code

• Within custom functions

• At the top of the code

What is the recommended order for placing functions in an Arduino program for better readability?

• Random order

• Loop function first, setup function last

• Setup function first, loop function last

• Custom functions first, setup function last

Why is it advisable to use comments in your Arduino code?

• To make the code run faster

• To identify function blocks easily

• To reduce the size of the code

• To increase the complexity of the code
