Everyone likes a good optical illusion. The right kind of trick can instill a sense of wonder in even the most jaded viewer.
Every year, the Neural Correlate Society, a nonprofit that promotes scientific research into perception and cognition, runs a contest to find the world’s best illusion. This year’s winner is a Dual Axis, a series of twisting rings that appear to move clockwise, counterclockwise, and up or down, depending on how you’re looking at it.
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.
