4/Inputs
Buttons, switches, dials, cameras, motion sen-
sors, and pressure sensors are all examples of
possible inputs to Galileo, and that list only
scratches the surface of inputs available to you.
Inputs help Galileo know what's happening in
the physical world so that a user can control
your device or the device can respond to its
environment. When combined with outputs,
inputs make your device interactive.
In this chapter, you will use Galileo's input functionality to:
• Understand how to read digital and analog inputs
• Experiment with a few different types of inputs
• Learn more about coding with Arduino
