 ====== DS3231 Real Time Clock ======
@@ Line 89: / Line 99: @@
 The sketch by Ralph Bacon only included setting and reading the time from the module and printing the result to the serial monitor. Most of this was used with only minor changes in this sketch. The implementation of the interrupt and the setting and clearing of alarm 1 was done by me.
+<WRAP center round info 100%>
+For anyone interested, I also made my own library for the DS3231 RTC module. The library allows setting and reading the time as well as using alarm 1 and 2 and also allows to read and change the status and control registers. There are also functions included for directly printing the time and the register settings to the serial monitor for an easy setup.
+The library can be downloaded as a zip file from {{ :amc2020:group_n:ds3231lib.zip |here}}.
+To understand what is done by the functions, I recommend checking the cpp file in the library folder and the [[https://datasheets.maximintegrated.com/en/ds/DS3231.pdf|DS3231 Datasheet]]. Example sketches will soon be included as well.
