Sorry if this is the wrong place to post this, but this is my first forum I've ever posted on. I am wanting to know is it possible to build a board that will allow me to have it attached to a keypad, so if i were to sms/text a specific number to it that it would register that number and then electronically input that number, but at the same time i would not want to loose the ability to manually type in the number. Is this possible? can you guys direct me to a working design that is almost the same? I am not clued up with circuit boards and things at all, so please help me in very simple English when it comes to the process involved.
Thanks in advance all. Regards
