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 ...

There are a few libraries available to decode the DCF77 time signal from Mainflingen, Germany but I decided to write my own using the simplest method I could devise. The result is presented here and ...

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.

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 ...

Clocks that read time via received radio signals have several advantages over their Internet-connected, NTP-synchronised brethren. The radio signal is ubiquitous and available over a fairly large ...
