Arduino uno User Manual

Figure 7—The Tabs menu in action
Not only can you create your own sketches using the IDE, but it also comes
with many example sketches that you can use as a basis for your own
experiments. Get to them via the File > Examples menu. Take some time to
browse through them, even if you don’t understand anything you see right
now.
Note that many libraries come with examples, too. Whenever you install a
new library (you’ll learn how to do this later), you should have a look at the
File > Examples menu again. It will probably contain new entries.
The Arduino IDE makes your life easier by choosing reasonable defaults for
many settings. But it also allows you to change most of these settings, and
you’ll see how in the next section.
