This is weird!
I am working on a project that uses the ds1307 TinyRTC module. This morning I saw it did not work any more. It just did not react. I used the TinyRTC in several projects and never had much problems with it.
I changed the battery. Nothing happened.
I changed to a third battery. Nothing happened.
I changed the TinyRTC module. Nothing happened.
I changed to a third TinyRTC module. Nothing happened.
I changed the Arduino (actually a Dccduino Uno). Nothing happened.
I changed to a third DCCduino. Nothing happened.
I changed the dalton wires. Nothing happened.
I tried the example scetches for Settime and i2c_scanner. Nothing happened.
If I disconnect the SDA/SCL wires I get
DS1307 Communication Error :-{
Please check your circuitry
Did the libraries change overnight? Did an A-bomb explode in the stratosphere and fry the electronics? All other stuff seems to work fine. I tried a I2C LCD unit and it works fine.
