It's a basic proof of concept that I'm putting together. It's honestly not 'for' anything in particular, I just have a few projects coming up that I plan to use a Web Server for, and when I tossed this on my Uno+Ethernet...

I saw there was a neat little form field. So I thought - "Hey, it'd be kinda cool if I could gather form data, and then tweet the value of a sensor... all with one web button." That was about it. I created a problem for myself and found that I didn't know how to (start solving) solve it. After trying to make sense of the Web Server Sketch above, I realized I was in over my head and thought I'd send an SOS to the community since they've been massive help before. I'm kinda new to parsing data, regex, and other stuff that most people probably think are basic. Sorry.
