Dear Arduino Community,
Recently, I have been wanting to build a box that would lock (using servos) for a certain amount of time as determined by the user. For those of you who have read the book “The City of Ember,” this box would be similar to the box containing instructions. This box is a commercial product of what I am trying to build.
I was hoping to have a potentiometer or button to set how much time to lock the box for, and then an lcd screen to display the remaining time. It would be nice to be able to lock the box for many days, or even months. Thanks, and if you have any ideas or suggestions, then please help. Thanks, icecats
