Lesson 1 Add Libraries
Once you are comfortable with the Arduino software and using the built-in functions,
you may want to extend the ability of your Arduino with additional libraries.
What are Libraries?
Libraries are a collection of code that makes it easy for you to connect to a sensor, display,
module, etc. For example, the built-in LiquidCrystal library makes it easy to talk to character
LCD displays. There are hundreds of additional libraries available on the Internet for
download. The built-in libraries and some of these additional libraries are listed in the
reference. To use the additional libraries, you will need to install them.
How to Install a Library
Using the Library Manager
To install a new library into your Arduino IDE you can use the Library Manager (available
from IDE version 1.6.2). Open the IDE and click to the "Sketch" menu and then Include
Library > Manage Libraries.
