arduino ethernet + led

flave7:
Hi all,
At school, for my project, I have present the features of the Arduino Ethernet POE + and I would like to know how to control a LED from the internet (in local network is enough for me) with a button in website.
If someone has an idea I'm interested because most Internet tutorial are not understandable.

Thank you for your precious help!

I don't see what we can offer that an internet tutorial. That is one of the most common things to do with an Ethernet shield. If you are having specific issues with code, then post the code and the issues that you are having, but other than that I'm not sure what you are expecting.
