Creating a GPS Treasure Box
Andrew did a write up of one of his projects that we would love to share. We wish you all a happy ❤️Valentines Day!❤️ — Many years ago I came across the idea for a GPS treasure box, from a post originally by Kenton Harris (I think - apologies if it was somebody else). Some called it a reverse geocache too, but in simple terms, it’s a locked box that only opens at a certain location. The idea behind the box was a very simple interaction - one button, and a screen. The process would go like this: Press button Screen lights up, and GPS begins scanning Screen tells you how many attempts you have left Once GPS has location, the distance from the target location in kilometers is shown One attempt is removed from total # of attempts Screen turns off Eventually, the target location would be found (and the box unlocks), or the attempts will run out and the box will be sealed shut forever! Inspired to create a fun adventure for myself and a friend on a weekend in Spain, I ordered all the relevant components including GPS module, Arduino Uno, batteries and a servo motor to lock the box.
