Using thresholds, we set three different volume categories and adjust the NeoPixel's color accordingly. These units are chained and each have an input side and an output side. Note: This board is intended to be used with 5V microcontrollers. Particularly suitable for small and medium dream color lighting projects. There are two ways this can be addressed: NeoPixel Stick 8 x WS2812 5050 RGB LED with Integrated Drivers.
Maybe, in the end, it will be a nice overview / how-to with tips, solutions and caveats.

it/yew) library, you can now control NeoPixels or WS2811/WS2812 LEDs directly from your Raspberry Pi! The Adafruit CircuitPython NeoPixel library solves the real-time control - Adafruit Electret Microphone Amplifier (ID: 1063) - Several Neopixels, you can mix and match o Adafruit Flora RGB Smart Pixels (ID: 1260) o Adafruit NeoPixel Digital LED strip (ID: 1138) o Adafruit Neopixel Ring (ID: 1463) Software requirements: - Adafruit NeoPixel library Connections: - 5 V to mic amp + - GND to mic amp - Analog pinto Neopixels come in many types, including both 5V and 12V variations and RGB, RGBW, and “NeoPixel” is Adafruit’s brand for individually-addressable RGB color pixels and strips based on the WS2812, WS2811 and SK6812 LED/drivers, using a single-wire control protocol. The end state: To have the Soundboard in Part A send a signal to the ProTrinket in Portion B to "brighten" the lights from 50/255 to about a 100-150/255 for X amount of time. Preferably physically close to the Neopixel. Connect your power supply ground to your Arduino ground. These amplifier ICs combine circuit design, manufacturing process innovation, and applications expertise to create products that simplify signal conditioning design. NJM2041D LOW-NOISE DUAL OPERATIONAL AMPLIFIER. For NeoPixel we use a similar framework for each of the effects. Its effective output impedance is about 125 ohms.
The controller takes 12V power from the rear parking light, GND and 12V signal from the brake lights (when applied). Now let us interface WS2812B Neopixel LED Strip with NodeMCU.
