Hi there i am working on digital electronics project which is basically an electronic lock. What it does is that you enter the security code into the keypad and press a button to enter it, if the code is correct the lock opens otherwise it doesn't. I also want the code to be re programmable.. I am hoping to keep it hardware only. The problem i am facing is that i want some sort of permanent storage in which the code is stored and compared and i don't have the slightest idea what to use for that. If anyone can guide it would be really appreciated.
