    PSA for anyone using this RTC (DS3231), there is a badly designed charging circuit on this particular module (ZS-042 and probably others). You must either use a rechargeable LIR2032 battery or disable the charging circuit. You can do so by cutting the trace or removing the diode or resistor. Otherwise, using a non-rechargeable CR2032 could cause it to swell and explode. Although, even with a rechargeable LIR2032, the charging voltage is too high at ~4.7 V relative to the spec of 4.2 V, which may also cause issues. The recommenced option is to remove the diode with a pair tweezers or by desoldering, and use a regular CR2032 battery. There is a thread about this issue on the Arduino forums.

    To anyone that was in my shoes where the serial moniter only prints nonsense, I oversaw the baud rate. If it's making a ton of ????, match your serial moniters baud rate to 115200 (as seen in the video).

    I'm having an issue with the programming part. I downloaded both libraries and it still doesn't work but I suspect, based of what I'm reading, that the library is isn't completely identifying certain variables/parts, such as:
    DS3231 rtc(SDA, SCL);
    Serial.print(rtc.getDOWStr());
    Serial.print(rtc.getDateStr());
    Serial.println(rtc.getTimeStr());

    people forget to say: when 5V is in use and non rechargeable battery, you MUST break the charging path - otherwise your 3V battery may explode ;-) if you connect to 3.3V it will not happen as there is a diode in the circuit. same no issue if you use 5V and rechargeable battery ;-)
    one more thing as bonus: this module has extra EEPROM that can be used ;-)

      First of all, thanks for the reaction. But I tried it in multiple ways, but the fact that it uses rtc.getTimeStr(); seems the confuse the system. Is this a matter of notation?

      @Mad Max yo chill out and Atef Ben Attia, you can probably use an if statement like this. You would need to save the hour part to a variable as well. This variable as well as the code would need to be in a loop so it constantly refreshes.
      if ((hour == 2) && (minute == 0)) {
      *insert what you want it to do here*
