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.
