Refrigerator Lights
===================
Refrigerator Lights is a simple blinkenlights update of the refrigerator of the [MunichMakerLab](https://munichmakerlab.de/) hackerspace.

It drives a small WS2812b LED strip based matrix of 15x10 LEDs behind a diffuse cover; which replaces the old lamp. 
Controllable by MQTT over ESP8266 WiFi module.
