Light and sound are two types of waves. Like radio and the waves that our cell phones make to communicate with each other. We are continuously surrounded by waves, but we never see them.
Until now! Because here, at the cradle of radio and television, sound waves are being visualized. Whistle, clap, talk, sing or scream and see the waves you produce yourself. Experience how waves travel through space and bounce off the walls. Discover how different tones also produce different waves.
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, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, 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.
