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.
