Alarm

Hi!

It seems i make some mistake writing.... nevermind

I have a strange problem with alarm code.
After 20 or so times my alarm stop working from unknown reason...
Can anybody have some idea?

here is the code:

 #include <Wire.h>
#include "RTClib.h"
#include <Time.h>
#include <TimeAlarms.h>

RTC_DS1307 rtc;

time_t syncProvider()     //sinhro vremena, funkcija radi isto što i RTC_DS1307::get()
{
  return rtc.now().unixtime();
}

int led = 13;

void setup()
{
Serial.begin(9600);
Serial.println("One timer is triggered every 15 seconds");
Serial.println();

pinMode(led, OUTPUT);

rtc.begin(); 
  setSyncProvider(syncProvider);
  Alarm.timerRepeat(15, RepeatTask);
}

void loop()
{
digitalClockDisplay();
Alarm.delay(1000);
}

void RepeatTask()
{
Serial.println("15 second timer");
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(1000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(1000);
}

void digitalClockDisplay()
{
// digital clock display of the time
Serial.print(hour());
printDigits(minute());
printDigits(second());
Serial.println();
}

void printDigits(int digits)
{
// utility function for digital clock display: prints preceding colon and leading 0

Serial.print(":");
if(digits < 10)
Serial.print('0');
Serial.print(digits);
}
3 
  delay(1000);               // wait for a second

Did you miss the part about needing to replace ALL calls to delay() with calls to Alarm.delay() instead?

It seems I miss that part.... :roll_eyes:

Thanx very much... working now......

Here is another problem...
The RepeatTask (15 sec) alarm working fine but MorningAlarm wont't work at all
I checked several times but I see nothing wrong?

Any Idea?

Code:

#include <Wire.h>
#include "RTClib.h"
#include <Time.h>
#include <TimeAlarms.h>

RTC_DS1307 RTC;

int led = 13;

void setup(){
  Serial.begin(57600);
  Serial.println("One timer is triggered every 15 seconds");
  Serial.println("The timer is triggered once a day");
  Serial.println();

  pinMode(led, OUTPUT);

  Wire.begin();
  RTC.begin(); 
  if (!RTC.begin()) {
   Serial.println("RTC failed");
   while(1);
  }
  
  Alarm.alarmRepeat(9,9,00, MorningAlarm); // change time 
  Alarm.timerRepeat(15, RepeatTask);

}

void loop(){
  //DateTime now = RTC.now();
  digitalClockDisplay();
  Alarm.delay(1000);
}

void RepeatTask()
{
Serial.println("15 second timer");
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  Alarm.delay(1000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  Alarm.delay(1000);
}

void MorningAlarm()
{
  Serial.println("Single timer");
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  Alarm.delay(2000);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  Alarm.delay(1000);
}

void digitalClockDisplay()
{
DateTime now = RTC.now(); // digital clock display of the time

if(now.hour()< 10)Serial.print("0");
Serial.print(now.hour(),DEC);
Serial.print(":");
if(now.minute ()< 10)Serial.print("0");
Serial.print(now.minute(),DEC);
Serial.print(":");
if(now.second ()< 10)Serial.print("0");
Serial.print(now.second(),DEC);

Serial.println();
}
