This new rock is unlike anything we’ve ever visited before. It’s a tiny frigid object about the size of New York City, orbiting in an area of the Solar System known as the Kuiper Belt. This region of space, located beyond the orbit of Neptune, is filled with possibly millions of small frozen objects. It’s a bit like a super distant Asteroid Belt. Except the bodies in the Kuiper Belt are thought to be incredibly primitive — leftover remnants from the birth of the Solar System. When the planets first formed 4.5 billion years ago, the materials in the Kuiper Belt region didn’t join together to form new worlds but instead remained as tiny fragments. And they’ve mostly stayed the same ever since.
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.
