I'm really sorry everyone about how dumb this might sound, but I am very new to using ethernet on an arduino. I now have an Ethernet R3 Shield for my arduino Uno, and I'd like to work on a project.
Essentially I just want, for now, to be able to press a button on my arduino (connected to the internet) and have a light turn on on another arduino connected to the internet, and vice versa. I'd like to say I have a pretty good understanding of the components and the language, I just have no clue how I would send a signal over the internet, or even connect my arduino to the internet for that matter.
Any suggestions on how would I do this? And more importantly, what resources could I use to learn some of this stuff? I've read several posts on this forum and other resources, but even the beginnings totally confuse me (I'm like totally blind when it comes to servers and porting, etc)
Thank you all so much for your help, A noobie in search of learning
