.. I'm not sure how you'd control the key holding mechanism?
First off, what is the point
and 14 switches for each of the key holders.
I think there are a number of things you'll want to ask yourself or plan for before starting the project. First off, what is the point? If you have to hand the customer a code number to get their key out, why not just hand them the keys? How would the keys be placed back in the mechanism afterwards? What would stop somebody from saving the code so they can get them out over and over again for free? What type of "switches" were you thinking would work to hold the keys?It sounds like a feasible project though I'm not sure how you'd control the key holding mechanism? I guess you could use servos but then you'd need to figure how to get more pwm channels.
You will need to think about how you are going to change the code to get a key. After it is used once, the code to get key 14 will need to be changed.
Well, leaning to do it could be one. Isn't that what hobbies are all about? Also, he could be n the situation that me may be able to e-mail the code to them. This would save having to travel to a specific place to hand out keys.

Would you want to download new codes or use a DIP switch in the box?I like your spirit. This will be a little difficult for a newbie, but not impossible.
Instead of programming the secret code each day... Why not add 328 each time it is used?
