what is rtc ? and how it is working ?
RTC stands for real tme clock.
RTC module code is ds3231 the code is given in the datasheet for all components . it is work in 3.3v 5v may kill the module.
it is used to maintain accurate time keeping when main power to the device is interrupted.

the rtc maintan maintains second,hours, day,date, month and year information.
real time clockThe date at end of the month is automatically adjusted for month with fewer then 31 days including corrections for leap years.
example : feburavary has 29 days in this period rtc changes the next month automatically.
the rtc operates in either 24 hours and 12 hours format ith AM/PM indicator
step 3: Benifts and features;
simple serial inerface connects to most microcontrollers eg:i2c
real time clock battery backup input for continious time keeping
operating temperature ranges
in commercial : (0*c to +70*c)
in industrial : (-40*c to +85*c)
step 4: APPLICATIONS :
gps
servers
utility power meters
step 5: PIN DESCRIPTION
in this module we have 6 more pins we use only 4.
1. gnd (Ground )
2.vcc (5v)
3.SCA (for serial clock input )
4.SDA (for serial data input/output pin)
