Arduino for Beginners - 2022 Complete Course - Arduino Setup and Loop Functions

The video tutorial introduces the basic structure of an Arduino program, highlighting the essential functions: void setup and void loop. It explains the importance of these functions for compiling and running code on an Arduino board. The tutorial details the execution flow, where setup is executed once and loop runs indefinitely. It also emphasizes the use of comments to enhance code readability and describes the roles of setup and loop in initializing and running application code.

What are the two main functions that should be present in an Arduino program?

What happens to the code inside the void loop function when the program is running?

Explain the purpose of the void setup function in an Arduino program.

How can comments be added in an Arduino program, and why are they useful?

Describe what kind of code you would typically write inside the void setup function.
