On the evening of October 29, 1969 the first data travelled between two nodes of the ARPANET, a key ancestor of the Internet. Even more important, this was one of the first big trials of a then-radical idea: Networking computers to each other. The men who symbolically turned the key on the connected world we know today were two young programmers, Charley Kline at UCLA and Bill Duvall at SRI in Northern California, using special equipment made by BBN in Cambridge, Massachussetts.
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.
