Hallo zusammen, Ich habe vor ein paar Monaten mir die Rheinturmuhr gebaut leider habe ich innerhalb einer Woche 5 Minuten Plus an Differenz bei der Uhrzeit. Verbaut ist dort ein RTC DS1307. Das Problem ist ein DCF77 mit anzuschließen ohne das ich ständig Fehlermeldungen bekomme.Habe da folgenden Sketch ( ohne DCF77 )
/* Rheinturmuhr mit NeoPixel WS2812 LED-Streifen */

wo müsste ich was eintragen damit der DCF77 funktioniert ? Vielleicht ist jemand so nett und kann mir weiterhelfen.
Bin Anfänger ohne viel Ahnung deshalb die komische Frage.Vielen Dank für Eure Hilfe
