==Introduction==
==Introduction==
The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal. The device incorporates a battery input, and maintains accurate timekeeping when main power to the device is interrupted. The integration of the crystal resonator enhances the long-term accuracy of the device as well as reduces the piece-part count in a manufacturing line. <br>

EASY plug DS3231 Clock Module

Introduction

The DS3231 is a low-cost, extremely accurate I2C real-time clock (RTC) with an integrated temperature-compensated crystal oscillator (TCXO) and crystal.
A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time.

It integrated with a battery input, which can maintain accurate timekeeping when power off. The integrated crystal resonator ensures the accuracy of clock. So this RTC solution should be worth to try.
Note: this module should be used together with EASY plug control board.

Specification

  • Temperature range: -40℃ to +85℃
  • Timing accuracy: about ± 5ppm
  • Output: 1Hz and 32.768kHz
  • High speed (400kHz), I2C serial bus
  • Supply voltage: 3.3V to 5.5V
  • Output Level: TTL level


Technical Details

  • Dimensions: 38mm*20mm*18mm
  • Weight: 5.4g


Connect It Up

Connect the EASY Plug DS3231 Clock module to control board using an RJ11 cable. Then connect the control board to your PC with a USB cable.

Upload the Code

Copy and paste below code to Arduino IDE and upload. 

#include <Wire.h>   // place file “Wire.h” under the directory “libraries” of Arduino
#include "DS3231.h"  // place file “DS3231.h” under the directory “libraries” of Arduino
DS3231 RTC;//Create the DS3231 object
char weekDay[][4] = {"Sun","Mon","Tue","Wed","Thu","Fri","Sat"};
//year, month, date, hour, min, sec and week-day(starts from 0 and goes to 6)
//writing any non-existent time-data may interfere with normal operation of the RTC.
//Take care of week-day also.
DateTime dt(2018,11,16,10,25,33,3);//open the series port and you can check time here or make a change to the time as needed.
void setup ()
{ Serial.begin(57600);//set baud rate to 57600
Wire.begin();
RTC.begin();
RTC.adjust(dt);//Adjust date-time as defined 'dt' above 
}
void loop ()
{ DateTime now=RTC.now();//get the current date-time
Serial.print(now.year(),DEC);
Serial.print('/');
Serial.print(now.month(),DEC);
Serial.print('/');
Serial.print(now.date(),DEC);
Serial.print(' ');
Serial.print(now.hour(),DEC);
Serial.print(':');
Serial.print(now.minute(),DEC);
Serial.print(':');
Serial.print(now.second(),DEC);
Serial.println();
Serial.print(weekDay[now.dayOfWeek()]);
Serial.println();
delay(1000);
}


What You Should See

Done uploading the code, open the serial monitor and set the baud rate to 57600, you should be able to see the time and the date.
