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 library and allows a ...

This Arduino code decodes the DCF77-signal without the use of interrupts. The DCF77 signal is broadcasted at 77kHz and can be received with a simple cheap receiver that cost €10.

We cannot easily adjust the clock of an Arduino microcontroller, but we can measure the frequency deviation of the nominal frequency and correct in software. The supplied software uses the pulses of a ...

His build really comes together by incorporating a noise resilient DCF77 decoder library by [Udo Klein] which is running on a separate Arduino Uno.

If you want to be sure that the output of our DCF emulator produces a valid DCF code signal, there are numerous Arduino based (test) projects on the internet with DCF77 decoders.
