      Hi everyone! As soon as I saw the WS2812B led strip, I thought: doing a vu-meter with these LEDs would be a nice thing!.

      I was looking for economical MEMS microphones with board (I didn't want to solder a board). I found two options: SPH0645LM4H and SPW2430.

      The SPH0645LM4H uses an I2S interface and the SPW2430 has an analog output. The second board (SPW2430) has two outputs: AC pin which has a capacitor in series to eliminate the DC output of the IC, and the output of the IC (...
