Hopefully someone can point me in the right direction for what I want to do. I am new to the arduino, but am learning.
I have a wood shop that I almost never lock up. Recently we have had a lot of suspicious characters around.
I would like to build a system that will lock and unlock the doors with a keypad.
I also want to put sensors on the door that will sound a alarm it they are opened while the system is armed.
have a look at KeypadTutorial and also consider using an RFID which may be simpler
