Simplified Arduino ADC - ESP8266 (nodemcu lua) communication + WS2812B LEDs

ESP8266 WiFi modules with very affordable price have become highly popular with hackers and developers around the globe, empowered with the great development of NodeMcu lua firmware, further simplifying the use. While there are a number of example setups on the web, none is very simple and effective in using the serial communication to push a few measurements from a microcontroller or Arduino to the ESP module, drive a number of WS2812B serial LEDs and display the raw values on the web interface.
