hi,
i am trying to use the following DS1307 module with arduino..
i am using spark fun arduino library and i test the demo code in library.i set the rtc to pc clock with 1 sec delay.
https://github.com/sparkfun/SparkFu.../examples/DS1307_RTC_Demo/DS1307_RTC_Demo.ino
i disconnect the module from the arduino and after 24 hours i found a delay about 20 SEC.
how can i solve the problem ?
