Vu-meter using a WiPy 2.0, some WS2812B and a SPW2430

This project is about connecting a Wipy 2.0 with a SPW2430 MEMS microphone and WS2812B led strip. The Wipy 2.0 measures the MEMS output and calculate the RMS of the signal on a defined time window and switches on the led strip proportional to this value simulating a vu-meter.

Hardware

  • Wipy 2.0
  • SPW2430 MEMS microphone
  • W2812B ledstrip
