I came up with an idea of an Arduino Board that is connected to the internet through Ethernet, and sends text with the GSM shield.
Text your zip code, City, or State to get a text with all the statistics for weather. Text "add" and your zip code, city, or state to be added onto a list that texts you when a major storm, or any warning in general has been issued. Using weather.com, the information is ripped directly from there and updated. Locally, the LCD screen connected to the Arduino Board will display requests for weather, time, date, how many people using the service, when a new phone number is added, etc.
I only have the Arduino Uno, SD card shield, Ethernet Shield, 20x16 LCD screen, and I am going to purchase the GSM shield.
Thing is, is that I have no experience with programming or Arduino designing, since I just purchased the board and components on 3/28/13.
Please post, personal message, or email me with help. I have no idea what I'm doing, and would like guidance. It's why I posted this, anyways.
