DS1307 based Clock using lcd




This project gives you a real time clock with the RTC chip DS1307. This RTC chip has inbuilt oscillator for clock and it has its own registers for full calender. In this project we dont take care about the days and we just use the time functions.

There are 3 push buttons on the circuit to change the time and the time is displayed over the LCD display. You have to provide battery backup for the RTC chip, so that the time runs inside the chip during power failure.

The code is written in Bascom basic, you can also download the proteus simulation file.
