I bought a Tiny RTC I2C module and it doesn't work. When i run the TimeRTCSet from TIME library all i get is:
Unable to sync with the RTC
0:00:00 0 0 1970
0:00:01 1 1 1970
0:00:02 1 1 1970
0:00:03 1 1 1970
0:00:04 1 1 1970
0:00:05 1 1 1970
0:00:06 1 1 1970
0:00:07 1 1 1970
The module is connected like this:
Vin -> 5V Gnd -> Gnd SCL -> A5 SDA -> A4
I'm using arduino uno.
I tried with a simple i2c scanner, but it returned two devices!
Scanning...
I2C device found at address 0x50 !
I2C device found at address 0x68 !
done
Only the clock is connected. I tried removing the battery for night to reset it, but it didn't fix it.
Could you help me?
