user46823: I need some help with a project I am doing involving the DS1307 RTC. I am trying to make what is essentially a way to mins quickly check the time which involves nine LEDs slowly lighting up every 10 so that I can quickly check time but looking at it. : So far I've tried TimeAlarms but I can't figure out how to do this. I have a Arduino Uno by the way.
Can someone possibly help?

user46827: Use the SQW pin on the DS3231 or DS1307 to create 1sec pulse, read it on your Arduino. There are very good libraries are available (like RTClib from adafruit).
