Chapter 1. Discover the Arduino Ethernet
Shield
In this first chapter of the topic, we will only focus on the basics and get started with the
Arduino Ethernet shield. In order to build more complex projects in the next chapters of the
topic, we first need to be absolutely sure that our shield is functioning correctly, and it can
connect to our local network and the Web.
To ensure this, we'll first assemble the hardware, and then build a simple Arduino sketch
that will connect to the Web, grab a test web page, and display it back inside the Arduino
Serial Monitor.
These will be the major takeaways of this chapter:
• First, we'll make sure that you have all the required hardware and software com-
ponents. We are also going to assemble the shield and the Arduino Uno board, and
connect everything to our local network via a router.
• Then, we will write the sketch that will connect your shield to your local network
as well as the Web, and this sketch will grab a test page to make sure your connec-
tion is working correctly.
• Finally, we are going to test this sketch and monitor the status of the Ethernet
shield on the Arduino Serial Monitor. From this first test of the shield, we'll be able
to tell whether the shield is correctly connected to the Internet or not.
