Before the escalator was invented, commerce and transportation were largely one-dimensional. Stairs and elevators were for the committed and purposeful, their limitations constraining vertical expansion, above and below ground. Stairs require patience and effort. Elevators have a unique, precise, and tightly constrained mission. The invention of the escalator changed everything: suddenly, a constant flow of people could ascend into the air, or descend to the depths. The escalator modified architecture itself, creating fluid transitions into spaces above and below. Now, in commerce and transportation, neither the sky nor the ground would be the limit.
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.
