Briefly introduced: Time and date with the Tiny RTC Module (DS1307 real time clock chipset)

The Tiny RTC breakout board with the DS1307 real time clock chip from Maxim Integrated Products allows time-and date-dependent circuits with the Arduino or other microprocessor environments. Data logger, timer or alarm clock are just some example applications. In addition, the board has an ATMEL 24C32 EEPROM chip with 32 Kbits memory and still the ability to add a separate temperature sensor (DS18B20).
