Ok, this is going to be a long one but hopefully I can get it all. Let me start off with the fact that I have never worked with Arduino or LCD paired with Arduino for that matter. I'm designing an escape room for my local museum to open in October for the week of Halloween. For one of the puzzels, I would like to have a globe with an LCD impeded into it and have reed switched around the globe in certain spots. One reed switch will be located in the place that the infection broke out (its a zombie-themed room). I want to design it so that when they put the pin with a magnet at the end of it over the right switch it displays a code for a lock on the LCD. I was also thinking it would be cool if when they put the pin over the wrong spot and trigger a switch it displays WRONG on the LCD and a 1 minute timer starts and they can't try again for that amount of time time to help prevent the escapers from just running the magnet around the globe until they find it. If anyone can help me with this project it would be greatly appreciated.
