FastLED + MSGEQ7

Audio reactive FastLED pattern using the MSGEQ7.

Hardware

MSGEQ7 breakout board (for audio)
This firmware uses the MONO version, not STEREO
(Notice the single OUT pin pictured below)

EBay	Amazon

ESP8266 dev board:
(probably any microcontroller supported by Arduino IDE will work)
(if you get one with pins pre-soldered, you can use jumper wires to connect the leds to the board)
(Otherwise, you will need to know how to solder on a connector of some kind)

NodeMCU 12-E	D1 Mini 12-F

Digital LEDs (WS2811/WS2812B/etc)

WS2811	WS2812B

Features

• Automatic Channel Analysis (Finds Bass and Treble Channels in realtime)
• Bass/Beat Hits will spawn a white pixel that fades over time
• Bass/Beat Hits will 'refresh' all white pixels to full brightness
• Treble/Vocal/Instrumental 'Hits' will spawn a pixel from a palette (Rainbow_p by default)
• Spawns are marquee'd cross every frame
