Invisibility seems like an incredible superpower until you think about it for more than a minute. See, vision is a two-way street. Light likes to bounce around between objects. Without that interaction, vision doesn’t work.
In an ordinary scenario, light races across the cosmos, coming primarily from our parent star. As it nears, it interacts with objects around us. Photons collide with the atmosphere, with plants and animals, with earth and sea, and bounce away. Those photons, having been altered either by absorption or reflection, then reach our eyes where they are taken in. Our minds paint a picture of the world around us, based entirely on the interaction of modified light entering our eyes.
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.
