From the example, setTime(8,29,0,1,1,11); is included in the setup, did you put this in to test it? Other than that, it should be working.

Tried this, changed the alarm time to 8:30 as per the example and it worked ! So why isnt it reading from the RTC time thats my question ?

Have i really managed to stump the knowledge of all the great Arduino Coders ?

Edit - Not sure if im on the right tracks here, but i thought as a test id put this in to see what the arduinos internal time actually is, and theres a mismatch, could this be the issue ?

I don't see anything obvious. How about putting a few serial.printlns inyour day, night, lightson, lightsoff, etc functions to see if the alarm is triggering them. At least you'll narrow it dow to a function problem or alarm problem.

Quick5pnt0,

Its an alarm issue, theres no LED change either on the relay or on a seperate status LED, however these do work when called by the switch, so the alarm just is not triggering. - See here for Screenshot of what happens when button pressed - http://gyazo.com/804dadf4df3828d889f5abdc8c631c7f.png?1359502250

John,

Thanks, being a webdeveloper helps with the structuring a little smiley-wink

Ive run the TimeAlarms Samples, they work fine, pressing the switch the feeding cycle kicks in fine and runs, i was subbing the times to test but nothing at all happens at the time, ive tried everything i can think of, using Arduino Uno, pulling time back from the arduino works fine (See http://gyazo.com/4a7299e4d4e2c8eafaeaffd972ca5bba.png?1359500543) - Any ideas ?

Ok guys, got my DS1307 today, wired her up and shes working fine, however got one problem, the alarms wont trigger ! - any idea where im going wrong here as ive been reading the examples etc and cant see anything obvious -

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

RTC_DS1307 RTC;


// RELAYS

int pumprelay = 3;
int filterrelay = 4;
int lightsrelay = 5;
int heaterrelay = 6;

//BUTTONS

int FeedingButton = 7;
int HeaterButton = 18;

//LEDS

int lightsled = 8;
int pumpled = 9;
int filterled = 10;
int FeedingLED = 11;
int heaterled = 12;


// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status

// the setup routine runs once when you press reset:
void setup() {
    Serial.begin(9600);
    Wire.begin();
    RTC.begin();
 
  if (! RTC.isrunning()) {
    Serial.println("RTC is NOT running!");
    // following line sets the RTC to the date & time this sketch was compiled
   
  }
 
  // initialize the digital pin as an output.
  pinMode(lightsrelay, OUTPUT);
  pinMode(lightsled, OUTPUT);   
  pinMode(heaterrelay, OUTPUT);
  pinMode(heaterled, OUTPUT);   
  pinMode(pumprelay, OUTPUT);
  pinMode(pumpled, OUTPUT); 
  pinMode(filterrelay, OUTPUT);
  pinMode(filterled, OUTPUT);   
  pinMode(FeedingButton, INPUT);
  pinMode(FeedingLED, OUTPUT);
  Serial.println("Startup Completed"); 
  FilterOn();
    Alarm.alarmRepeat(23,00,0, Night);  // 8:30am every day
    Alarm.alarmRepeat(06,00,0, Day);  // 8:30am every day
    Alarm.alarmRepeat(21,55,30, Feeding);  // 8:30am every day
}

// the loop routine runs over and over again forever:
void loop() {
 
  DateTime now = RTC.now();
 
    Serial.print(now.hour(), DEC);
    Serial.print(':');
    Serial.print(now.minute(), DEC);
    Serial.print(':');
    Serial.print(now.second(), DEC);
    Serial.println();

 
    // read the state of the pushbutton value:
  buttonState = digitalRead(FeedingButton);

  // check if the pushbutton is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState == HIGH) {     
    // Start Feeding Cyle   
      Feeding();
  }
  else {
    // Continue Normal Program

 }
 
 Alarm.delay(1000); // wait one second between clock display
}

void Feeding() {
   digitalWrite(FeedingLED, HIGH); // Set Feeding LED On
     Serial.println("Feeding Cycle Started"); 
  LightsOn();
  PumpOff();
  FilterOff();
  delay(6000);
  digitalWrite(FeedingLED, LOW); // Set Feeding LED Off
    Serial.println("Feeding Cycle Ended"); 
  LightsOff();
  PumpOn();
  FilterOn();
  delay(6000);

}

void Night () {
  LightsOff();
  PumpOff();
}

void Day () {
  LightsOn();
  PumpOn();
}

void LightsOn() {
 digitalWrite(lightsrelay, HIGH); // Set Lights On
 digitalWrite(lightsled, HIGH); // Set LED On
   Serial.println("Lights On"); 
}

void LightsOff() {
 digitalWrite(lightsrelay, LOW); // Set Lights Off
 digitalWrite(lightsled, LOW); // Set LED Off
   Serial.println("Lights Off"); 
}

void PumpOn() {
 digitalWrite(pumprelay, HIGH); // Set Pump On
 digitalWrite(pumpled, HIGH); // Set LED On
   Serial.println("Pump On"); 
}

void PumpOff() {
 digitalWrite(pumprelay, LOW); // Set Pump Off
 digitalWrite(pumpled, LOW); // Set LED Off
   Serial.println("Pump Off"); 
}

void FilterOn() {
 digitalWrite(filterrelay, HIGH); // Set Filter On
 digitalWrite(filterled, HIGH); // Set LED On
   Serial.println("Filter On"); 
}

void FilterOff() {
 digitalWrite(filterrelay, LOW); // Set Filter Off
 digitalWrite(filterled, LOW); // Set LED Off
   Serial.println("Filter Off"); 
}

i am struggling to find any readup on how to program an RTC

The simplest would be to use your arduino to keep time: presumably the arduino is running all the time.


It is, however i may be away from my arduino for extended periods of time, so therefore would rather use an RTC so that even if the power drops once the power comes back on the whole thing restarts itself.

I have been considering the DS1307 RTC, do you think this will be suitable ?
Yes this is a good choice.
The Time library contains examples for the DS1307 RTC. http://playground.arduino.cc/Code/time
It also contains TimeAlarms which can be used to do things on a timed basis.

Thanks for that Larry, id been reading the library but had missed a very obvious link in there, reading through some of the examples this should be fairly easy to do.

Apologies, forgot to add the most important part !

Hey everyone,

Ive just started with arduino and am slowly getting my head around it, im currently trying to build a Fishtank controller that is automated with a manual switch that can be pressed to enable feeding.

Now i have the basics in place, the switch works and activates the feeding cycle, but i am struggling to find any readup on how to program an RTC, what i want it to do is at X time turn on the lights and at x time turn them off, but then i also need this for the other relays as well.

Heres my current sketch -

Code:
/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 
  This example code is in the public domain.
 */
 
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:

// RELAYS

int pumprelay = 3;
int filterrelay = 4;
int lightsrelay = 5;
int heaterrelay =6;

//BUTTONS

int FeedingButton = 7;
int HeaterButton = 18;

//LEDS

int lightsled = 8;
int pumpled = 9;
int filterled = 10;
int FeedingLED = 11;
int heaterled = 12;


// variables will change:
int buttonState = 0;         // variable for reading the pushbutton status

// the setup routine runs once when you press reset:
void setup() {               
  // initialize the digital pin as an output.
  pinMode(lightsrelay, OUTPUT);
  pinMode(lightsled, OUTPUT);   
  pinMode(heaterrelay, OUTPUT);
  pinMode(heaterled, OUTPUT);   
  pinMode(pumprelay, OUTPUT);
  pinMode(pumpled, OUTPUT); 
  pinMode(filterrelay, OUTPUT);
  pinMode(filterled, OUTPUT);   
  pinMode(FeedingButton, INPUT);
  pinMode(FeedingLED, OUTPUT);
 
}

// the loop routine runs over and over again forever:
void loop() {
 
    // read the state of the pushbutton value:
  buttonState = digitalRead(FeedingButton);

  // check if the pushbutton is pressed.
  // if it is, the buttonState is HIGH:
  if (buttonState == HIGH) {     
    // Start Feeding Cyle   
      Feeding();
  }
  else {
    // Continue Normal Program

 }
}

void Feeding() {
   digitalWrite(FeedingLED, HIGH); // Set Feeding LED On
  LightsOn();
  PumpOff();
  FilterOff();
  delay(600000);
  digitalWrite(FeedingLED, LOW); // Set Feeding LED Off
  LightsOff();
  PumpOn();
  FilterOn();
  delay(1000);

}

void LightsOn() {
 digitalWrite(lightsrelay, HIGH); // Set Lights On
 digitalWrite(lightsled, HIGH); // Set LED On
}

void LightsOff() {
 digitalWrite(lightsrelay, LOW); // Set Lights Off
 digitalWrite(lightsled, LOW); // Set LED Off
}

void PumpOn() {
 digitalWrite(pumprelay, HIGH); // Set Pump On
 digitalWrite(pumpled, HIGH); // Set LED On
}

void PumpOff() {
 digitalWrite(pumprelay, LOW); // Set Pump Off
 digitalWrite(pumpled, LOW); // Set LED Off
}

void FilterOn() {
 digitalWrite(filterrelay, HIGH); // Set Filter On
 digitalWrite(filterled, HIGH); // Set LED On
}

void FilterOff() {
 digitalWrite(filterrelay, LOW); // Set Filter Off
 digitalWrite(filterled, LOW); // Set LED Off
}

Anyone know of any really good guides for RTC at all ?
