Digital Clock and Temperature Monitoring

DIGITAL CLOCK and Temperatur Monitoring

This is a project making program digital clock and temperatur monitoring using Arduino UNO.

Come on join my blog

source code:

#include <virtuabotixRTC.h>

#include <LiquidCrystal.h>

//pin LCD 20x4

LiquidCrystal lcd(7, 6, 5, 4, 3, 2);

//pin RTC ke arduino (CLK, DAT, RST)

virtuabotixRTC myRTC(10, 11, 12);

//lm35

const int lm35 = A0;

float masuk =0;

float konversi, ukur = 0;

void setup()

{

lcd.begin(16, 2);

lcd.setCursor(2, 0);

lcd.print("JAM DIGITAL");

lcd.setCursor(2, 1);

lcd.print("version 1.0");

delay(2000);

lcd.setCursor(0, 0);

lcd.print("DUINO ELEKTRONIK");

lcd.setCursor(0, 1);

lcd.print("made in LAMPUNG");

delay(2000);

lcd.clear();

//format RTC detik, menit, jam, banyak hari dalam satu minggu, hari, bulan, dan tahun

//tidak diaktifkan agar mengikuti jam pada PC kita

//myRTC.setDS1302Time(00, 00, 00, 6, 14, 9, 2018);

}

void loop()

{

DS1302();

suhu();

delay(1000);

}

void DS1302()

{

// This allows for the update of variables for time or accessing the individual elements.

myRTC.updateTime();

lcd.setCursor(0, 0);

lcd.print(myRTC.hours);

lcd.print(":");

lcd.print(myRTC.minutes);

lcd.print(":");

lcd.println(myRTC.seconds);

lcd.setCursor(0, 1);

lcd.print(myRTC.dayofmonth);

lcd.print("/");

lcd.print(myRTC.month);

lcd.print("/");

lcd.print(myRTC.year);

}

void suhu()

{

masuk = analogRead(lm35);

konversi = (masuk*5000)/1023;

ukur = konversi/10;

lcd.setCursor(11, 0);

lcd.print("SUHU");

lcd.setCursor(10, 1);

lcd.print(ukur, 1);//satu angka dibelakang koma

lcd.print(char(223));

lcd.print("C");
