RGB Graphic Equalizer driven by ESP8266

Amir Avni has shared the details of his cool RGB graphic equalizer build, which is controlled by the ESP8266 hardware programmed with the NodeMCU firmware. The RGB LED strings are controlled through WS2812, while the equalizer colors are chosen through a Web interface over Wifi.
RGB graphical equilizer
Two weeks ago I got my ESP8266 Version 12, which is a new version of the ESP8266 micro-controller with more GPIOs, so it seems some nice things can be done with it. If you haven’t heard of the ESP8266 check this older postfrom the blog. Also, I got the MSGEQ7 chip, which is a chip that outputs an analog equalizer from a sound signal. I was looking for a fun project to do with those two items, one which can help me also to learn LUA script, the language that is used to program the ESP8266. Finally, I’ve created this project: An equalizer display controlled by ESP8266 with the NodeMCU firmware, where the equalizer colors are controlled via WiFi. Check the video:
