Function Example Two: Arduino Course 8.2

In this lesson, the instructor recaps the previous session on Arduino programming, focusing on reading temperature from an LM34 sensor and converting it to Fahrenheit. The lesson then delves into variable scope, explaining the difference between global and local variables. It highlights the importance of function prototypes, even though the Arduino IDE handles them automatically. The session concludes with a practical example of refactoring code by creating a function for serial printing, demonstrating the benefits of modular code.
