Click To Download :https://www.arduino.cc/en/Main/Software

SPECIFICATIONS

DS3231 RTC MODULE

TM1637 display is a 4-digit seven segment display.TM1637 is a chip which is used for driving the 7-segment display.TM1637 has finds its applications on Digital Clock, Programmable Timer, Digital Thermometer, Decimal Counter, Stopwatches.

The TM1637 display has four pins:

CLK (Clock)

DIO (Data I/O)

Vcc

GND

As we know that Vcc and Gnd pin goes to 5v and Gnd in the Arduino board. The CLK and DIO pins should be connected to any of the digital pins on the Arduino board.

#include

RTC_DS3231 rtc;

#define CLK 8

#define DIO 9

TM1637Display display(CLK, DIO);

void setup () {

display.setBrightness(0xA);

display.setColon(true);

}

void loop () {

DateTime now = rtc.now();

int t = now.hour() * 100 + now.minute();

display.showNumberDec(t, true);

delay(1000);

}

WORKING

In this project we are using 4 digit display that will display clock on that using ds3231 rtc module that will display clock 24 hours on that 4 digit fnd display.

Battery operated	Yes, 1 nos 9V battery included
