Adafruit customer Kenton Harris used a reverse geocaching box to propose to his girlfriend (she said yes). After the project build and successful proposal, he shared how he built the reverse geocache box with us. We thought others may be interested in building a similar box for their own proposals, or for fun!
A reverse geocaching box works similar to other geocaching devices. It will guide you to certain coordinates on earth and instead of finding a geocache located at those coordinates, you carry the box with you, and it opens for you at a predetermined destination. This is also a great way to do a scavenger hunt (making someone go to multiple locations before the box opens).
Thanks again Kenton for sharing your story and tutorial with us!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
