Croon a tune, croak like a frog, hum, hoot, or holler—you don’t need to be Pavarotti to create dazzling shapes and patterns with the power of your voice. By humming, singing, or talking into the Vocal Visualizer, you’ll be able to see sound as vibration (or pressure waves) and experience cool laser-light patterns that are reflected on a wall or other surface. It’s a fun and slightly psychedelic introduction to concepts such as Lissajous patterns and resonant vibration modes. A Pink Floyd soundtrack is entirely optional.
Each Tuesday is EducationTuesday here at Adafruit! Be sure to check out our posts about educators and all things STEM. Adafruit supports our educators and loves to spread the good word about educational STEM innovations!
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.
