Arduino YUN Ether net configuration
In a previous article we showed you how to control digital pins over over serial, and showed how such a simple thing can be so powerful. One major downfall with that is you need to be nearby to send commands… So today we are going to look at doing the same thing, but this time we will be doing it over the internet using the Arduino Ethernet Shield. As per our usual style, I am going to make this as simple as possible so it is easier to extend. So if you you are looking for something with an HTML interface, this article will not be covering that. The Arduino Ethernet Shield is capable of being both a client (like a web browser), and a server, and with the onboard SD card-slot can be quite powerful by hosting up full websites, but for this article we are just looking at using the Arduino as a server and you will control it simply by going to a specific URL. Note that the Ethernet Shield uses digital pins, 10, 11, 12, and 13 for itself, so it is best to leave these al...
