Thank you Mr. Ryan for your quick response. I have checked all the connection found to be OK. LED2 jumper also in open condition, 3V coin cell is available in the DS1307 kit. When i measured voltage across SCLand SDA pin of DS1307 with respect to ground and found to be 4v in both pins. Please find below my circuit diagram. Please note that even if i remove DS1307 kit from circuit then also i am getting the value like, 2000/0/0 0:0:0 , so as you said i am agree that DS1307 is not communicating, but how to make it working? Kindly support to fix this issue. Regards, HASEEL
