Hi,
I use an arduino pro micro and a RTC DS1307 with RTCLib-master library. I would like to enter in sleep mode during 10minutes and after wake up the arduino and write some data on SD card. Is it possible to wake up the arduino thanks to the SQ pin of the DS1307 after 10 minutes ?
Thank you
What does the data sheet for the DS1307 say about the frequency of the output on the SQ pin ?
Hint: What you want to do would be heaps easier if you used an RTC with an alarm function.
No.
