Need to find buddy that went diving, fishing, or kayaking with out in the open ocean. We should stick with each other at all times, but sometimes we get separated. Trying to find your far off buddy when you are low in the water is a tad bit difficult.
The a light on the NeoPixel ring turns red to show where north is. A blue light points to the direction of where the other device is (purple if north and direction of buddy is the same). The OLED screen displays GPS connectivity, battery level, distance and bearing to the other device. Although there is a LiPo protection circuit (cut off is ~2.4V), you should never let the battery get lower than 3.3V. The protection circuit is just to make sure nothing catastrophic happens when battery goes too low.
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.
