Chapter 5. Working with Displays
In Chapter 4 , Accessing the GPIO Pins , you learned how to connect with the outside world
using jumper wires, breadboards, and components. In this chapter, you'll learn different
connection approaches to show how you can connect an additional capability to Arduino
using hardware shields designed for Arduino. Specifically, I'll cover two topics: how to add
a functionalities by adding hardware that is designed to plug into Arduino or shields and
how to connect several types of displays to Arduino. We'll use several different types of
display shields to illustrate the different communication modes that can be used to address
the different types of hardware.
