This repository contains a DCF77 decoder library for Arduino. It was designed with the goal to create the most noise resilent decoder possible. There are also some ready to run examples. For the ...

Measure: Frequency + Period + Pulse + Pulse/period + Capacity + Event counting. Bonus: decode DCF77 pulses and show date and time. The DCF77 pulses are also used to calibrate the system clock.

Although the idea behind this project is quite straight forward, the implementation is a bit more difficult. The software may need some modification to be compatible with your DCF clock, so we have ...
