LED Beer Mat/Coaster

This is one of the first functional parts i made to test how well i could get something to just clip together without any glue and it turned out very well and once its cliped together is tricky to get back apart

The LED ring is from Adafruit https://www.adafruit.com/product/1586 its controlled using a Adrunio nano https://www.arduino.cc/en/Guide/ArduinoNano

I cannot remeber where is got the code/sketch form but it looks really good when its on
