Chapter 3. Adding Display Functionality
In Chapter 2, Accessing the GPIO Pins, you learned how to connect to the Galileo and its GPIO pins using jumper wires, breadboards, and components. In this chapter, you'll learn more about adding functionality by adding hardware designed to plug into the Galileo. In some of these examples, you'll use special hardware designed to be plugged into the Galileo's GPIO pins; these are called shields.
