This is a fork of JeeLab's fantastic real time clock library for Arduino. For details on using this library with an RTC module like the DS1307, PCF8523, or DS3231, If you look at the library source code it will be clear why begin() returns true.If you need a DS1307 for compatibility reasons, check out our DS1307 RTC breakout. This is easily achieved by downloading a library and driver bundle. The RTC is an i2c device, which means it uses 2 wires to to communicate. These two wires are We also have a great tutorial on Arduino library installation at: This resets the RTC chip. Now load up the following sketch (which is also found in Examples>RTClib>ds1307) and upload it to your Arduino with the On the Arduino UNO, these pins are also wired to the Analog 4 and 5 pins. This is For the RTC library, we'll be using a fork of JeeLab's excellent RTC library, which is available on GitHub. Look for the Adafruit RTClib (there may be others!) RTClib.
