![]() ![]() It will report the ipAddress to the serial monitor This isn’t really that hard, it is more of a pain when especially if you want to plug it into a different network as the same settings may not work.Īs of Arduino 1.0, the library does support DHCP So you should be able to just plug it into your network and have it work. Without an extra library, the ethernet code does not support DHCP and therefore requires that we hardcode the IP Address,gateway address, and subnet mask for your network. Getting the ethernet shield on the internet is going to differ depending on your network, but no matter what, you need to plug it into an ethernet port connected to the internet – So make sure you do that. Note that the Ethernet Shield uses digital pins, 10, 11, 12, and 13 for itself, so it is best to leave these alone and not try to use them for anything else. ![]() 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. So if you you are looking for something with an HTML interface, this article will not be covering that. 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.Īs per our usual style, I am going to make this as simple as possible so it is easier to extend. 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. ![]()
