The DS1307 has a built-in power-sense circuit that detects power failures and automatically switches to the backup supply. Timekeeping operation continues while the part operates from the backup supply. For this tutorial you just need an Arduino Nano 3.0, a DS1307 real-time clock module a breadboard and wires. Arduino real time clock with DS1307 This post shows a simple real time clock and calendar example using an Arduino UNO board and DS1307 RTC chip where time and calendar are displayed on 1602 LCD screen and it can be set with two push buttons. real time clock DS1307 with Arudino circuit is given below. pin number 5 and 6 of DS1307 is connected with SCL and SDA pins of Arduino. If you have already gone through above mentioned article on LCD interfacing with Arduino and other basic articles to get know how of Arduino, you can easily understand following circuit.
