Hello Arduino Forum,
This is my first project for the arduino (that I'll be starting after I have finished my Inventor's Kit circuits). I understand that there are shields for ethernet, but is there a communication module (GSM) that can be used with the arduino, which would allow text msgs nationwide? I am very new to this. Thank you for all of your help in advance.
The communication module I was going to use for this originally was this:
But then realized I don't think I can use this with the arduino
