The first line of code for this project is: // Project 1 - LED Flasher This is just a comment in your code. You can tell it s a comment because it starts with // and any text that begins this way will be ignored by the compiler. Comments are essential in your code; they help you understand how your code works. As your projects get more complex and your code expands into hundreds or maybe thousands of lines, comments will be vital in making it easy for you to see how each section functions. You may come up with an amazing piece of code, but you can t count on remembering how it works when you revisit it several days, weeks, or months later. Comments, however, will remind you of its functionality. Also, if your code is meant to be seen by other people, comments will help that person understand what is going on in your code. The whole ethos of the Arduino, and indeed the whole Open Source community, is to share code and schematics. I hope that when you start making your own cool stuff with the Arduino you will be willing to share it with the world, too. There is another format for making comments; it is a block statement bookended by /* and */ , like so: /* All of the text within the slash and the asterisks is a comment and will be ignored by the compiler */
