The DCF77 library adds the ability to your Arduino to read and decode the atomic time broadcasted by the DCF77 radio-station. Example sketches have been added to
1) illustrate and debug the incoming signal
2) use the library and convert to different time zones.

In order to exploit all features in the library, Both the Time and
TimeZone library are included.

version 0.9.8 adds support for inverted pulses


  1. Cerco libreria EEprom per arduino due

  2. Hi,

    I m trying to compile you example code with Arduino IDE 1.0.5. But I not able to compiling it properly. I have copied error below .

    ‘EEPROM’ was not declared in this scope.

    please help me with this ……..


  3. Hi Thijs,
    have You seen anywhere DCF device project (sketch) under Esplora?
    There are pins D1, D0, D7, / D3, D11 (both on TK)
    For example, I tried read DCF via D3 on INT 1. Result: null
    Regards from Polish

  4. Ok, I have a solutions. Interrupt=0
    Regards .

  5. Hi,

    I’m intersting with your librairy, to communicate between NetDuino and ArDuino.

    Is your projet compatible with .Net Micro ?



    • Hi Vincnet, I do not have a NetDuino, so I haven’t tried. I never optimized for memory footprint or efficiency, so even if it works, it might be a bit heavy for the NetDuino. It looks like a cool idea, though, so let me know what you find!
