Electronic number Lock

[Foxoff50]

I'm new to arduino and I'm wondering if it would be possible to create an electronic number lock that would automatically generate a new code everytime a code is used. And it would send the new code to my phone via SMS. Any advice on how I could get that done? I know I'd have to write code for that but how would I get my hands on a circuit board for it.

Many, many people have used Arduino to send SMS messages and have posted tutorials or project descriptions on line. Others have made keypad/door locks and posted those projects too.

Google will be happy to show them to you.

Thanks. I will look into it.
