Arduino DCF77 library The DCF77 library adds the ability to read and decode the atomic time broadcasted by the DCF77 radiostation. It has been designed to work in conjunction with the Arduino Time ...

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 ...

If you have already studied the circuit diagram, you will have noticed that the speaker is connected to 2 PWM pins of the Arduino. Here is a statement from the author of the Talkie.h library: >> On ...

[Brett] just completed his DCF77 Master Bracket Clock, intended to be a backup to an old logic controlled clock he made. For our readers that don’t know, DCF77 is a German longwave time signal whose ...

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.

About 20 years ago I recycled and modernized a very old nixie clock built by my father in the 70's, with an 87C51 and a DCF77 module which replaced digital ICs and 50Hz derived timebase. About 20 ...
