8 independent microcontrollers generate an oscillating square pulse that is emitted as current and voltage to a coil, that create a variable electromagnetic field. four induction coils capture the invisible field that is amplified once again in to electromagnetic waves sent to speakers, which use electromagnetic induction to convert the electrical current back into sound. spinning the platform and controlling the independent necks, attack sustain release and decay could be achieved

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.
