Hey everyone. I do back yard snowmaking. This comming year i would like to automate my system. I want to see what my system pressures are and control simple sprinkler valves when i click a button. I dont want to have a computer on 24/7...
i have
-uno
-eirther net
-two pressure transducers
-micro sd card
My problems are
-how do i display an html page that i made using notes?
-How do i make it a webpage that can be seen from a phone or an internet devise when im at school or away?
-how do i hit a button that says automate and will turn on the valves when there is a temp reading below 28 out?
Thanks!!

Web Server
A simple web server that shows the value of the analog input pins.
using an Arduino Wiznet Ethernet shield.
Circuit:
* Ethernet shield attached to pins 10, 11, 12, 13
* Analog inputs attached to pins A0 through A5 (optional)
