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.
