PIC-based real-time clock with DS1307

This PIC project uses an I2C Real Time Clock IC (DS1307) and a four digit seven segment display to create a standard desk clock.

The DS1307 (RTC) Real Time Clock IC (an I2C real time clock) is an 8 pin device using an I2C interface (although the data sheet does not mention I2C to avoid royalty payments!).

You can use any PIC microcontroller that has an ADC and enough memory to hold the program and enough pins for the display multiplexing.
