    If you ever experience problems with a DS1307 check the following:

    If you don't have a Backup Battery connected to the Vbat Pin pull that Pin LOW.

    With Vbat floating the DS1307 might be put into low current mode and will not recognize any data input.

    I have realized this on a few of my DS1307s and it has taken me quite some time time to find out what the problem was.

    regards

    Ralph
