i want to turn on realy in every hour using rtc DS1307, but want to stop it between 10pm to 8am (night sleeping time). please help me to creat that code....
There should be examples available that came with the RTC library.
Should find them under examples.
BTW, a DS3231 is a much much better RTC.
Where are you stuck ?
Can you read the time from the RTC and print it ?
using this code i want to turn on a realy in every hour using RTC DS1307 with a inturrept between 10pm to 7am. please help to modify this code...
#define RELAY1 8 //Relay1
#define RELAY2 7 //Relay2
#define an_hour 60000UL // 1 second = 1000 milliseconds,,1 minute = 60 seconds,,1 hour = 60 minutes,,12 hours = 12 * 60 * 60 * 1000 = 43,200,000
unsigned long startTime;
void setup()
{
pinMode(RELAY1, OUTPUT);
pinMode(RELAY2, OUTPUT);
digitalWrite(RELAY1, HIGH);
digitalWrite(RELAY2, HIGH);
startTime = millis();
}
void loop()
{
if (millis() - startTime > an_hour)
{
digitalWrite(RELAY2,LOW); // Turns ON Relays 1
delay(10000); // Wait 2 seconds
digitalWrite(RELAY1,LOW); // Turns ON Relays 1
delay(20000); // Wait 2 seconds
digitalWrite(RELAY2,HIGH); // Turns Relay Off
delay(5000);
digitalWrite(RELAY1,HIGH); // Turns Relay Off
//delay(2000);
startTime = millis();
}
}
using this code i want to turn on a realy in every hour for only 2 seconds using RTC DS1307 with a inturrept between 10pm to 7am. please help to modify this code...
#define RELAY1 8 //Relay1
#define RELAY2 7 //Relay2
#define an_hour 60000UL // 1 second = 1000 milliseconds,,1 minute = 60 seconds,,1 hour = 60 minutes,,12 hours = 12 * 60 * 60 * 1000 = 43,200,000
unsigned long startTime;
void setup()
{
pinMode(RELAY1, OUTPUT);
pinMode(RELAY2, OUTPUT);
digitalWrite(RELAY1, HIGH);
digitalWrite(RELAY2, HIGH);
startTime = millis();
}
void loop()
{
if (millis() - startTime > an_hour)
{
digitalWrite(RELAY2,LOW); // Turns ON Relays 1
delay(10000); // Wait 2 seconds
digitalWrite(RELAY1,LOW); // Turns ON Relays 1
delay(20000); // Wait 2 seconds
digitalWrite(RELAY2,HIGH); // Turns Relay Off
delay(5000);
digitalWrite(RELAY1,HIGH); // Turns Relay Off
//delay(2000);
startTime = millis();
}
}
Are you going to use the RTC ?
If yes, look at the RTC library examples and see if you can come up with a rudimentary sketch.
NEVER ever use delay( ) in your sketches (unless you know what ramifications it causes).
Does this sketch work with your DS1307 RTC connected ?
// Date and time functions using a DS1307 RTC connected via I2C and Wire lib
#include <Wire.h>
#include "RTClib.h"
RTC_DS1307 rtc;
char daysOfTheWeek[7][12] = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};
byte lastReadSecond;
//******************************************************************************************
void setup ()
{
Serial.begin(9600);
if (! rtc.begin())
{
Serial.println("Couldn't find RTC");
while (1);
}
if (! rtc.isrunning())
{
Serial.println("RTC is NOT running!");
// following line sets the RTC to the date & time this sketch was compiled
// rtc.adjust(DateTime(F(__DATE__), F(__TIME__)));
// This line sets the RTC with an explicit date & time, for example to set
// January 21, 2014 at 3am you would call:
// rtc.adjust(DateTime(2021, 9, 28, 11, 18, 0));
}
} //END of setup()
//******************************************************************************************
void loop ()
{
DateTime now = rtc.now();
if (lastReadSecond != now.second())
{
//update to the new second
lastReadSecond = now.second();
Serial.print(now.year(), DEC);
Serial.print('/');
Serial.print(now.month(), DEC);

thanks for replying . this code works perfectly. but now i want to use this code in my 7 segment led clock, please help me to combine this code with my led clock code...

this is the full code
So we see.
But please go back and edit each of your previous posts to correctly put the code in code tags. 
Otherwise people start to wonder whether they will ever get to the end. 
fortunately I have got it... I have successfully compile these two code..
