I'm trying to create a reverse geocache box to give to a friend before the end of the month. Most of the code is basically taken from this instructables https://www.instructables.com/id/3D-Printed-Electronic-Puzzle-Box/ I wanted the box to be able to tell if it's been too the location even after power has been removed, so I wanted it to keep track through eprom. I thought I edited the code to work with only one switch and one servo, as I don't need multiple locations, and switches. I've compiled with no errors, but I can't get anything to display on the LCD, or keypads to work. Hopefully someone can help me with the coding, I can easily do the electronics, but coding has always been my downfall.
