Hallo, ich versuche gerade meinen zweiten Code hinzubekommen... ich schaffs aber ums verrecken nicht....
Ich habe mir diesen Code aus verschiedenen zusammen genommen. Ich möchte (am Schluss) damit ein relais schalten für eine bestimmte Zeit.. Quasi eine einstellbare Eieruhr... ich bekomme aber einfach nicht hin das es mir richtig auf dem Display angezeigt wird. Würde sich jemand erbahmen und mir den Code umschreiben ? Und wenn ihr ganz gut drauf seit evtl. dazu erklären was ich falsch gemacht habe.
Im moment ist da denke ich ziemlich Chaos drin 
Ich muss gestehen das ich mich noch nicht auskenne, aber ich möchte mich irgendwie auch nicht geschlagen geben.... Ich spiele da jetzt schon Tage rum und verliere ziemlich den Spass an der Geschichte.
Hoffe auf Hilfe von euch.
Danke Andy
