Hallo Leute,
in diesem Teil des Forums habe ich tolle Hilfe von euch dabei bekommen, einen Windmesser mit dem Arduino zu realisieren :
http://forum.arduino.cc/index.php?topic=158479.0
Dabei ist jetzt das Problem aufgetaucht, dass meine Real Time Clock (diese hier: http://www.watterott.com/de/Real-Time-Clock-Module-RTC) scheinbar ihren Geist aufgegeben hat, auf einmal (sie hat einen ganzen Tag im Einsatz durchgehalten). Habt ihr eine Idee wie ich testen kann, ob sie funktioniert bzw. inwieweit ich versuchen kann sie anzusteuern?
Hab es mit verschiedensten Libaries probiert, die aber alle nicht zum Erfolg geführt haben.
Wenn ich beispielsweise diesen Sketch ausführe:

Scheinbar wurde die Uhr nicht gestellt.
Bräuchte da dringend eure Hilfe!!
Falls meine RTC widererwarten defekt, kaputt, zum wegwerfen sein sollte, hat jemand von euch eine Idee, wo man solch eine günsitg (gern auch schon mit Stiftleiste dran gelötet) beziehen kann?
