In Steven Spielberg’s classic sci-fi film Close Encounters of the Third Kind, humanity is visited by an advanced alien species. In the absence of any common language, the aliens divert to simpler communication methods, those of sound and light.
In Earth’s oceans, a similar type of communication is happening among some of the smallest and most ubiquitous organisms on our planet. While communication and socialization are often thought of as existing only in the realm of higher animals, the ability to share information is important even for the very small and very simple.
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.
