A Spectrum Analyzer shows the loudness of different frequency bands (low, mid, high) in real-time, letting you visualize music. Using a RasPi, RGB LED Strip and some wire, make yourself a dynamic display and media player. This project is based on some great python xmas light code from the LightShowPi project, and advanced users can even configure it for song voting via SMS!
The project runs in Python, even including the audio processing. It’s just able to play and analyze mp3s in realtime as long as your Pi isn’t doing anything else.
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.
