hallo zusammen...
habe mir diesen: http://eckstein-shop.de/DS1302-Real-Time-Clock-Module-CP14001-C83
geholt...
nun folgendes Problem:
Zeit wird soweit angezeigt, allerdings wechselt er in etwa alle 20 sec von 08:..... auf 04:....
Die 08: Uhrzeit stimmt soweit...
und dann will ich eigentlich ein relay bei einer bestimmten Zeit schalten.
Relay ist noch nciht angeschlossen, habe es aber mit einer RGB versucht...
Geht aber iwie auch nicht...
wo ist der Fehler?
