Flow Chart Process

5.4 Coding

//#include <SPI.h>
#include <DS3231.h> //Library for RTC module (Download from Link in article)
DS3231 rtc(SDA, SCL);
void setup()
{
Serial.begin(9600);
//SPI.begin(); /* Enable the SPI interface */
rtc.begin(); // Initialize the rtc object
rtc.setTime(13, 52, 00); // Set the time to 12:00:00 (24hr format)
rtc.setDate(13, 3, 2018); // Set the time to 12:00:00 (24hr format)
}
Void loop()
{
}

6. Result

• 7 Segment display real time clock by get time from DS3231.
• Button 2 (Middle): press a second 7 Segment will go to set time turn on LED mode. In mode set time if click less than a second on Button it will increase number on 7 Segment.
• Button 3 (Right): press a second 7 Segment will go to set time turn off LED mode. In mode set time if click less than a second on Button it will decrease number on 7 Segment.
• Button 1 (Left): press a second in set time mode it will save time value. But if we click less than a second it will change digit for edit number of time.
• LED will turn on/off when time we set the same real time.
