Dear Arduino community
I'm a beginner Arduino user and am attempting to replicate a 24-hour alarm clock demonstrated in a tutorial found at: https://diyhacking.com/arduino-alarm-clock-using-real-time-clock-lcd-screen/.
I downloaded all the most updated libraries associated with the DS3231 Real Time Clock module.
When I attempt to run the following program (I am not the author of this code, as it is directly taken from the page I linked above), I am met with an error that seems to be a result of missing a key library.
Can anyone tell me which libraries I need to install to eliminate the error?
#include <DS3231.h>
#include <Wire.h>
#include <LiquidCrystal.h>
LiquidCrystal lcd(2, 3, 4, 5, 6, 7);
DS3231 rtc(SDA, SCL);
Time t;
#define buz 11
int Hor;
int Min;
int Sec;
void setup()
{
Wire.begin();
rtc.begin();
Serial.begin(9600);
pinMode(buz, OUTPUT);
lcd.begin(16,2);
lcd.setCursor(0,0);
lcd.print("DIYHacking.com");
lcd.setCursor(0,1);
lcd.print("Arduino Alarm ");
delay(2000);
}
void loop()
{
t = rtc.getTime();
Hor = t.hour;
Min = t.min;
Sec = t.sec;
lcd.setCursor(0,0);
lcd.print("Time: ");
lcd.print(rtc.getTimeStr());
lcd.setCursor(0,1);
lcd.print("Date: ");
lcd.print(rtc.getDateStr());
if( Hor == 11 && (Min == 32 || Min == 33)) //Comparing the current time
with the Alarm time
{
Buzzer();
Buzzer();
lcd.clear();
lcd.print("Alarm ON");
lcd.setCursor(0,1);
lcd.print("Alarming");
Buzzer();
Buzzer();
}
delay(1000);
}
void Buzzer()
{
digitalWrite(buz,HIGH);
delay(500);
digitalWrite(buz, LOW);
delay(500);
}
The error returned when I compile and run this program is as follows:
sketch_oct29c:17: error: no matching function for call to
'DS3231::DS3231(const uint8_t&, const uint8_t&)'
DS3231 rtc(SDA, SCL);

Cheers!
