Screens and buttons are nice, but it's time to add network capabilities to our Arduino projects. We're going to use an Ethernet shield with an Arduino UNO to build a few basic network-enabled gadgets.

W5100 Ethernet Shield R3 (PoE) ~$10
* There are examples of Ethernet projects build into the Sketch IDE
Ethernet Server with Analog Input
Code Example: _01_WebServer
* Code for this example is under "File - > Examples -> Ethernet -> WebServer"
* We need to change the following in the code:
-- Set the IPAddress to "192.168.0.229"
-- Change the "for" loop so there are only 2 Analog reads
* We need to wire the following:
-- Power to the outer POT pins
-- Center pins to A0 and A1
** Play with the "Refresh" setting to show a quicker refresh
