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.
