Make a Simple Clock

The project aims to collect data from RTC clock and display it using LCD

Hardware Components:

LCD Display

Arduino UNO

RTC Clock            

Jumper wires

 

Software apps and online services

Arduino IDE

---

Develop the circuitr by making connections as shown above.

Code

• This part gives the setup and main loop of the program

void setup()
{
lcd.init();
lcd.backlight();
Serial.begin(9600);
Wire.begin();
DS3231_init(DS3231_INTCN);
t.hour=8;
t.min=30;
t.sec=0;
t.mday=23;
t.mon=12;
t.year=2019;
DS3231_set(t);
if(t.hour<13){
if(t.hour>0){
lcd.setCursor(3,0);
lcd.print("Good Morning !");
}
}
if(t.hour<23){
if(t.hour>19){
lcd.setCursor(4,0);
lcd.print("Good Night !");
}
}
if(t.hour<20){
if(t.hour>12){
lcd.setCursor(2,0);
lcd.print("Good Afternoon !");
}
}
}
void loop(){
DS3231_get(&t);
lcd.setCursor(6,2);
lcd.print(t.hour);
lcd.setCursor(8,2);
lcd.print(":");
lcd.setCursor(9,2);
lcd.print(t.min);
lcd.setCursor(11,2);
lcd.print(":");
lcd.setCursor(12,2);
lcd.print(t.sec);
