15,000 years ago, some water froze atop the Tibetan Plateau and became part of a glacier. While humans were busy domesticating dogs, the ice entrapped millions of microscopic organisms per square inch. Many of the tiny life forms died, and their genomes—the only proof that they had been there in the first place—slowly degraded. Then, in 2015, scientists from the U.S. and China drilled down 50 meters into the glacier to see what they could find.
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, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, 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.
