Simple Arduino DCF77 Decoder
This is a simple decoder for the German [DCF77](http://en.wikipedia.org/wiki/DCF77) time signal for the Arduino. There are already several DCF77 decoders out there for the Arduino. [But I wanted to do one on my own](http://photron.blogspot.de/2014/06/arduino-dcf77.html).
Quite a while later I came around and build an actual [clock](https://github.com/photron/arduino-clock) out of it and decided to put it on GitHub and here it is.
