Real Time Clock Module-DS1307
Real/Actual time clock module is primarily based on ds1307 rtc ic.The ds1307 real-time clock (rtc) is a low power, complete BCD (binary-coded decimal) clock or calendar plus 56 bytes of SRAM. Cope with and data are transferred serially thrugh an i2c, bidirectional bus. The clock/calendar presents seconds, minutes, hours, day, date, month, and year records. The quit of the month date is robotically adjusted for months with fewer than 31 days, such as corrections for bounce 12 months. The clock operates in either the 24-hour or 12- hour format with am/pm indicator. The DS1307 has a built-in strength-feel circuit that detects electricity screw ups and routinely switches to the backup supply. Timekeeping operation maintains at the same time as the element operates from the backup deliver.
