For the first few hundreds of thousands of years after the Big Bang, the universe was so hot that atoms couldn’t exist. Instead, everything was a violent morass of orange plasma made of elementary particles. Think of the universe as having been one gigantic star making up all of existence and you’ll be pretty close. Because of the dense collection of energetic particles, free electrons couldn’t travel unimpeded. Instead, they bounced off other particles like balls on an endless Plinko board. Reality was a pile of flashbulbs in a house of mirrors.
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. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
