Roughly 470 light years from Earth, in the constellation Taurus, there is a star system that looks uncannily similar to a younger version of our own solar neighborhood.
Not only does the system have a Sun-like star, called DM Tau, it has two dust rings that orbit at comparable distances to the asteroid belt and Neptune. All known planetary systems are built out of these dusty circles, which are called protoplanetary disks. Over millions of years, these huge clouds conglomerate into larger objects like asteroids and planets.
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.
