Build a mini VU meter inspired project using NeoPixels and CircuitPython! Powered by the QT Py RP2040, use a PDM microphone to turn audio data into a dazzling display with NeoPixels!
3D print a snap fit case to house the electronics with the mic exposed in the back cover. The grid isolates the 16x NeoPixels and a piece of Black LED acrylic diffuses the LEDs.
