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. :Here is a rough 3D model of the housing of the arduino 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?

    start by learning how to light up the LEDs .... then learn how to use the DS1307 RTC .... tutorials can be found on the web – jsotola May 23 '18 at 3:51

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).
