<p>Tinker.it made a pretty neat little shield called the EthernetShield, so I figured I’d pick up a couple to make some projects.</p>
<p>The Ethernet Shield is designed to allow the Arduino base module to connect to the internet easily as a standalone unit. The module carries an onboard WIZnet W5100 Ethernet chip, which provides a network (IP) stack capable of both <span class="caps">TCP</span> and <span class="caps">UDP</span>, as well as a standard RJ45 Ethernet jack. It supports up to four simultaneous socket connections. An Ethernet library writes sketches that connect to the internet using the shield.</p>
<p>The Ethernet shield connects to an Arduino board using long wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another shield to be stacked on top.</p>
