Introduction to User Defined Functions: Arduino Course 8

The video tutorial introduces the concept of functions in programming, focusing on user-defined functions. It explains how functions work as black boxes, taking inputs and producing outputs. The tutorial covers the syntax of user-defined functions, including return types, function names, and parameter lists. Practical examples, such as converting Fahrenheit to Celsius and adding sensor readings, are provided to illustrate the concepts. The video concludes with a review of the function components and a promise of more detailed examples in future lessons.
