From Team Laser Drums: Trent, Johnny Yan on Hackster.io:
Music can be expressed and modeled in so many different ways, and as engineers we are taking advantage of that. The drum boxes were fabricated in the makerspace, and when hit create a midi signal that can be computed and turned into any sound imaginable. The visual display takes a microphone’s input, and runs the Fast Fourier Transform algorithm on it to get a list of amplitudes across different frequencies and display that on a set of NEOPixel strips.
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.
