I have an Nano V3.0 3.0 Data Record Logging Shield Module For Arduino Nano Recorder 3.3V With SD Card Interface Module RTC Real Time Clock likes this (https://bit.ly/2INhYll). When I try to use SQW as a interrup pin to measured each 10 min (this is just an example) does not work. However when I use a clock like this (https://amzn.to/2IKHrfj) everything is OK the Arduino board Sleep & Wake up each 10 min without any problem using SWQ as an Interrup PIN. The clock and MicroSD work well in both cases, the problem is only with the Pin Interrup.
Thanks in advance
Post you code so we can see where the problem might be. Use code tags.
Here is the code but I thin the problem no is the problem.
