Sir Tim Berners-Lee invented the World Wide Web in 1989, envisioning a global information space where documents and other web resources could be identified with uniform names, where documents and resources could be retrieved in a standard way, and where documents could be connected by hypertext links. To this end, Sir Tim introduced a universal resource naming scheme based on URIs and URLs; the HTTP protocol for sending and receiving information across the Internet in a scalable and decentralized way; and the HTML markup language, which provided a standard way for documents to be created and displayed in a device-independent manner and linked to other documents. In addition, Sir Tim created the first web browser and web serving software, and he did so in an open-source fashion that catalyzed the Web’s further development.
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.
