ESP8266 Neopixel Controller

# ESP8266 Neopixel Controller
I have bought a couple of ESP-01S boards without any project really in my mind. But recently I have discovered cool looking WS2812B (Neopixel) adapters for these boards, so that gave me an idea for a project.

After several iterations I have developed little device, that enables to control WS2812B strips/rings either throught web interface, through MQTT commands or through REST API. It has also one button, that can switch various colors and effects.
What can it do:
* provides web interface that enables to select any color, save it to EEPROM, start an effect
* when enabled, the WS1228B strips can be controlled via MQTT commands (color, effect, off)
* REST API is also available to set color or effect
* button click cycles through saved colors, double click cycles through available effects and long click turns Neopixels off

Project can be used in home automation systems as it provides several interfaces that could be easily integrated into for exa
