2/First Steps
Blinking an LED is commonly the first thing to
try with a new hardware development board.
It's easy to do and it confirms that you have ev-
erything working correctly. If you've tried pro-
gramming before, your first step may have
been to get your code to print the text “Hello
world.” Getting an LED to blink on a hardware
development board is its way of saying “Hello
world.”
By the end of this chapter, you'll learn a few of the different parts of the Galileo,
what tools and components you'll need to work with it, and how to install the
development software and upload code to the board. To test things out, you'll
use Galileo to make an LED blink.
