Beginning Arduino Programming

Writing Functions

So far in this chapter, we have seen some additional functions that are part of the main Arduino library, as well as some that we have written. We've also looked at how these functions can extend the capabilities of our code. Functions provide the programmer with the ability to compartmentalize chunks of code that are related by a very specific purpose. We are not limited to only those functions that are provided in the Arduino programming environment, as in fact, writing functions is the bread and butter of writing source code for C and something that any seasoned Arduino programmer will do to make their code function better, take less memory space, make the code better organized, reduce the possibilities for errors, and generally ...
