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, see the guide at: https://learn.adafruit.com/ds1307-real-time-clock-breakout-board-kit/overview
|
||
|
|
||
|
To download. click the DOWNLOADS button to the right, and rename the uncompressed folder RTClib.
|
||
|
|
||
|
Place the RTClib folder in your *arduinosketchfolder*/libraries/ folder.
|
||
|
You may need to create the libraries subfolder if its your first library. Restart the IDE.
