Download Ds1307 Clock Arduino Images. In the near future i plan to refactoring the libraries. Using this module is simple, rtc part communicates with the microcontroller using i2c protocol.
Arduino Digital clock using MAX7219 and DS1307 RTC. from mytectutor.com Ds1307 is a low power serial real time clock with full binary coded decimal (bcd) clock/calendar plus 56 bytes of nv sram. Simply put the chip sends data in decimal form such that each decimal form is now insert the power pins coming from the arduino. With circuit, code and simulation.
Well, it is a real time clock (rtc) ic that is simple to use, low cost and easy available.
If you don't understand about i2c. But the arduino start the code by adjusting the time to 2pm again. Install temperature sensors on ds1307 module and try to make a cool graphic clock showing the environment temperature with tft lcd 2, 4. This allows the module to retain the time, even when it's not being powered up by the arduino.
