This is an awesome geocache locator with a great write up. Minimal soldering so it can be easily assembled and disassembled. Shared by seanhodgins on Instructables:
The Arduino Geocache Locator is a small device that lets you program in GPS locations, and then you can use the LEDs on the top as a navigation tool to get to your location. I love making gifts for my family members for Christmas, especially for my little nephew, and I have wanted to pursue this idea for awhile, so I thought it would make a great gift for him for Christmas this year.I also created a small story about having to locate 4 missing stones which I have hid around his town in various locations. He can go and find these geocaches with his mom when they go out to explore.
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.
