Hello all, I just started to work with the Arduino and I was wondering if anyone know how to send and read signals from the Cellular Shield with SM5100B. http://www.sparkfun.com/commerce/product_info.php?products_id=9607
I would like to be able to send the Arduino a text message saying, for instance, "Open door" and then the Arduino would send a pin high to activate a door lock or something. It would also be nice if I could then tell it to send a text message back saying "door unlocked". I would appreciate any insight on this issue and possible some sample code.
Thank you!
