What is the I2C address of the DS3231?
The DS3231 uses a fixed I2C address of 0x68. This address is hardwired in the chip and cannot be changed, unlike some other I2C devices that have configurable address pins. If you're placing the DS3231 on the same I2C bus as an LCD1602 (which is typically at 0x27), there is no conflict since the addresses are different.

Why does my DS3231 not trigger the alarm on the SQW pin?
The square-wave output must be disabled using rtc.writeSqwPinMode(DS3231_OFF); otherwise, the pin will not switch to alarm-interrupt mode.

How to Create a Clock Using Arduino , DS3231 RTC Module and OLED Display : 9 Steps (with Pictures) - Instructables
November 30, 2021 - How to Create a Clock Using Arduino , DS3231 RTC Module and OLED Display: I have made a couple of clock project in the past. I have always used DS1306 module to do it. I received the backlash from my viewers. They questioned why I would use that particuler RTC module labeling it as not relaible.
