So I am taking on this project where I want to build safe that is password protected. I am going to use a keypad to give access to the safe with a combination code. The issue is that I only want the user to gain access to the safe once a day regardless of the code. So I had two ideas. One would be that there´s an auto-generated password every day - I´m not sure I like this idea. It seems harder than it needs to be. The other would be if I could somehow restrict the user in code.
I am not an Arduino expert, although I´ve dabbled with it some. My question is if this is do-able and I would also appreciate a nudge in the right direction.
I havent started the project so I dont have any code to supply as of yet. But I guess I will be using an arduino, a keypad and a solenoid lock.
I appreciate every bit of help. Thanks
