    Musical Neopixels (WS2812B)

    äIn my opinon, it is way better to actually sample an audio-source (as in, read the signal straight off of an unused output) instead of using a microphone. For something like bass detection, a simple lowpass filter on your audio signal is enough to produce a reasonable voltage to get with analog.Read(), which can then in turn be mapped to the PWM of some LEDs for exampe.
