Arduino clock :
Hi guys, welcome to meworkstelugu in this section. We make a project Arduino clock using RTC clock module and 16*2 LCD display.
Arduino clock project will be help to show the time and date. This very easy project you can easily understand this project. Now let's talk about what are the components required for this project.
Arduino clock with RTC components :
- Arduino BuyNow
- RTC clock module BuyNow
- 16*2 LCD module BuyNow
- Breadboard BuyNow
- connecting wires BuyNow
If you want to buy Arduino components, I am giving my affiliate links. If you buy the components using my affiliate links, it will help to our channel and website growth. so do these small help.
Making video of Arduino clock by using RTC and LCD :
Watch the below video. This video will be help to make this project.
Arduino uno clock circuit diagram :
connect the all the components as shown in the below circuit diagram
Arduino uno clock code:
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
#include <RTClib.h>
RTC_DS1307 rtc;
LiquidCrystal_I2C lcd(0x27,16,2); // set the LCD address to 0x27 for a 16 chars and 2 line display
char daysOfTheWeek[7][12] = {"SUN", "MON", "TUE", "WED", "THU", "FRI", "SAT"};
void setup ()
{
Serial.begin(9600);
// lcd.prinit();
lcd.backlight();
lcd.begin();
if (! rtc.begin())
{
lcd.print("Couldn't find RTC");
while (1);
}
if (! rtc.isrunning())
{
lcd.print("RTC is NOT running!");
}
rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));//auto update from computer time
//rtc.adjust(DateTime(2014, 1, 21, 3, 0, 0));// to set the time manualy
}
void loop ()
{
DateTime now = rtc.now();
lcd.setCursor(0, 0);
lcd.print(daysOfTheWeek[now.dayOfTheWeek()]);
lcd.print(" ");
lcd.print(now.day());
lcd.print('-');
lcd.print(now.month());
lcd.print('-');
lcd.print(now.year());
lcd.setCursor(0, 1);
lcd.print("TIME : ");
lcd.print(now.hour());
lcd.print(':');
lcd.print(now.minute());
lcd.print(':');
lcd.print(now.second());
//lcd.print(" ");
}
If you have any doubts regarding to this project, contact me on Instagram or comment on YouTube video. I will help with my best.
