I'll be doing some soldering work, happy to chat and answer questions!
P.S. Still learning the process of livestreaming, working on getting the mic levels higher, thanks for the patience!

![ESP32 NeoPixel VU Meter For Audio Signals | MAX9814, WS2812B, and Arduino
• Description:
In this video tutorial I show you how to build a Volume Unit (VU) meter using an ESP32, a pair of NeoPixel/WS2812B LED sticks, and a MAX9814 mic on a breakout board. I go over the steps of assembling the hardware, and writing the software using the Arduino IDE, so that the audio signal is read from the mic, and a set of LEDs—proportional—to the amplitude lights up using a wide range of colors.

Second day of testing out a new streaming rig. Happy to chat and answer questions!
P.S. Third time streaming so still a little rough. Learning the process to make the next one much smoother! Thanks for the patience.
