RTC DS1307 INTERFACING WITH AT89C51

                   Here RTC (Real time clock) is the heart of timing systems. Nowadays all the systems are running based on time, here rtc has inbuilt battery backup to keep on running without external supply.
it updates it's register without external power supply. 
We can see many applications based on RTC in day to day life, for Ex., Mobile phone is the essential one.

Here we have interfaced RTC DS1307 with AT89c51 using I2C(Inter Integrated circuit).

here the code has been written in Embedded C and compiled using Keil uvision 3. and simulated in proteus 6.4. 

Operating system Windows 7. 
If you want any guidelines to install proteus in windows 7, just mail me or comment here.
