(Another) DIY LED Controller - Simple Arduino Style

int ontime = 12 ; // time of day (hour, 24h clock) to begin photoperiod

So from here the blue light starts at 12 and fades in for the first 60 minutes and then what? Does the White light starts fading in at this point or does the 120 minutes are counted from 12 pm? The white will start ramping in after the 60min mark. Then it will continue to ramp up for the next 120 min. I am confused, can anyone clarify this?

then after the white have fully ramp up, it will stay there for the next 4 hours. Then it will start to ramp down, white first for 2 hours then blue for 1 hour.

Hope this helps.

Thanks a lot for the help katchupoy, this clarifies my problem.

As for problem #2 for the temperature probe I am still having problems, yesterday I had it all working and today the temperature was basically stuck at 76 and when I uploaded a new code it showed 185F. Can the probe be bad? I did wire the 4k7 resistor. Any help will be appreciated.

I think I figured out what my problem with the temperature is.
The temperature readings are getting stuck once the arduino is doing the fading of the blues and whites, once that is done and the leds are at 0 or 255 the temp readings become actual temp readings. So whatever the last temp reading was when the fading starts is the reading that will be shown until the fading is over. The alarm will not even respond during this stage even if the temp shown is lower than the set temp for the alarm.

Did anybody else notice this? I am using Version_1_00_16x2. Do the other versions have the same problem or was it fixed? Thanks.

I will bump this for you so that others can see your issues. I am sorry that I cannot help you with this since my original build does not have this feature.
Hope others can help you.

I just ordered a bunch of stuff so I will be trying to build a controller as well. I hope you don't mind alot of questions and providing some help as I have zero experience with programming and zero experience with electronics but if I ask the right questions and get the right guidance I should be able to this (I hope) thanks guys.

Im sure what you are looking for is here somewhere. Just keep on reading, i guess.

katchupoy, Very long, but Very informative thread. Nice Job to all ! Thank you!

I have never worked with a arduino before, and so far there is so much info here my controller is almost complete.

main parts i have are SainSmart Arduino Uno w/ the 16x2 button sheld, SainSmart 4 relay 5v module, rtc. 2 temp from ebay, and cree led, three 48p drivers 12 white 24 blue and the 10v wall plug from rapid

I still am in the process of putting everything in the radio shack project box's, but have some Questions.

I have not tested the drivers yet with this but the relays are giving me issues. relay 1 and 2 seem to click on and off correct, but 3 and 4 have issues.
but temps and clock works

digital
pin 13 relay 1 Powerhead
pin 12 open
pin 11 led white
pin 3 led blue
pin 2 relay 2 other powerhead
pin 1 temps
pin 0 moon or sump light "not installed yet on tank, another non dim driver cree led"


analog
a1 "set to ph, have no clue when i would build this"
a2 "want for relay 3" for fuge light
a3 Relay 4 " to fun my fans"
a4 and a5 for RTC


i will post the code in a min. see is anyone can fix a few issues. Thanks

well, i guess my temps are not working, they stay the same now, but before i was playing with the code they did work

[katchupoy]

maybe the same issue with crazyreef at post #1252 ???

[SchnitzelReef]

So now the real question...???? How much for you to build one for me?? lol but seriously...? i would def be interested if u were building these and selling them...let me know

[Dan_Cochran]

Originally Posted by katchupoy

it could be, ill take a look and see if mine does the same..

ok, with the A removed

int fuge = 2; // implace of A2
int fan = 3; // inplace of A3

the relay board leds on relay 3 and 4 shut off and temps read 185 either way, if i unplug them temps, i get -196.60
but with A2 and A3 the leds light on relay 3 and 4

I dont think im switching from analog and digital correct in the code somewhere.
after leds are done ramp i will check again. I did find out im not that great at understanding the code.

[Dan_Cochran]

I know i have been playing with the code trying to get relay 3 and 4 to work, and tried a different copy of the temp library, but all at about 10 pm temps started working again

crazyreef looks not to be alone

[wardda]

I am working on getting my LED controller running and I'm reading through the original katchupoy sketch listed on the google source site and I see there are a couple of relays listed ledPin1 and ledPin2. I'm assuming these are physical relays that are turning the meanwells on and off is that correct?

Dan

[Dan_Cochran]

ok, I think i am getting on to somthing.

I dont think this should be working like this, its like the uno is confused on what pins i am saying what is on.

I was playing around and when i had issues with temps and changed the delay that i thought was for getting temps.

PHP Code:

   while (countdown>0)
        {
          onesecond(); // updates clock once per second
          countdown--;
          relay2();
          relay1();
        }
      }
    }
  }

// DS18B20 display
sensors.requestTemperatures(); // Send the command to get temperatures
[COLOR="Red"]delay(100);                     //  This is what i changed, it was 250[/COLOR]

float temp1=0, temp2=0;

  //lcd.setCursor(13, 1);
  //lcd.print("Led Temp:");
temp1= sensors.getTempFByIndex(1);
  //lcd.print(sensors.getTempFByIndex(1)); 
  //lcd.print((char)223);
  //lcd.print("F");
 
//  lcd.setCursor(2, 1);
//  lcd.print("Tank Temp: ");
temp2= sensors.getTempFByIndex(0);
//  lcd.print(sensors.getTempFByIndex(0)); 
//  lcd.print((char)223);
//  lcd.print("F");

if ( (temp1) > 81 )
    {
   // digitalWrite(fan, HIGH);
    analogWrite(fan, 255);
    digitalWrite(alarm, HIGH);
    delay(1000);
    digitalWrite(alarm, LOW);
    } 


when i changed it, relay 4 on the board pin a3 ,it shut on and off faster
temps still work.

I simply dont think the code is telling the uno to use the correct pins for stuff going from analog to digital.

[katchupoy]

@wardda...

In my orginal sketch. I have 4 pins assigned.

Two pins will be assigned on pwm that will control the drivers. This also means it will only control two channels. White and Blue.

Another two (analog) pins are used to control relays. These relays are meant for physical 5 volt relays that control power heads. This will simulate wavemaker.

Hope this helps.

@Dan....

I wish I could help. But the original sketch of mine did not include temp on it. Like what I've told wardda, my limited knowledge only extends to controlling the light via PWM and controlling powerheads via analog thru 5v relays.

[katchupoy]

Dan if you look at my original sketch. I believe the only way to incorporate something without it waiting for the whole thing to finish is to incorporate it within the "LOOP"

Example, I created/defined a "function" relay1 and relay2. If I will add this after the loop, then what happens is it will wait for the whole light function to finish and then it will run relay1 and relay2.

Again, this is coming from a person who has very limited knowlede with sketching...

So I ended up doing is,

1) define the function. (in your case... your temp)

PHP Code:

void relay1()  //FUNCTION TO TURN ON AND OFF RELAY 1.
{ 
  unsigned long currentMillis = millis();

  if(currentMillis - previousMillis1 > interval1) 
  { 
    previousMillis1 = currentMillis;   
    if (ledState1 == LOW)
      ledState1 = HIGH;
    else
      ledState1 = LOW;
    digitalWrite(ledPin1, ledState1);
  }
} 


2) then insert it inside the "LOOP"

PHP Code:

........  int countdown = ((whiterampup*60)/10); // calculates seconds to next step
        while (countdown>0)
        {
          onesecond(); // updates clock once per second
          countdown--;
          relay2();
          relay1();
        }
      } 
    }
  } 


[katchupoy]

I apologize if I am no help. I was not able to follow the more advanced sketches because they went so fast and I got left behind. Im beginning to get the itch again, maybe I will have courage to move to the next level...

I want, temp controller and maybe a PH monitor or something. Im not even sure if this is possible. I already have the PH probe, so I guess why not?

I have never worked with a arduino before, and so far there is so much info here my controller is almost complete.

main parts i have are SainSmart Arduino Uno w/ the 16x2 button sheld, SainSmart 4 relay 5v module, rtc. 2 temp from ebay, and cree led, three 48p drivers 12 white 24 blue and the 10v wall plug from rapid

I still am in the process of putting everything in the radio shack project box's, but have some Questions.

I have not tested the drivers yet with this but the relays are giving me issues. relay 1 and 2 seem to click on and off correct, but 3 and 4 have issues.
but temps and clock works

digital
pin 13 relay 1 Powerhead
pin 12 open
pin 11 led white
pin 3 led blue
pin 2 relay 2 other powerhead
pin 1 temps
pin 0 moon or sump light "not installed yet on tank, another non dim driver cree led"


analog
a1 "set to ph, have no clue when i would build this"
a2 "want for relay 3" for fuge light
a3 Relay 4 " to fun my fans"
a4 and a5 for RTC


i will post the code in a min. see is anyone can fix a few issues. Thanks

Dan,

Let me explain you something. Im not sure im correct, but it is how i understand it.... maybe this will help you?????


Look at this picture...



Pay special attention on the digital pins on the top... specially the ones with "~" this means that these are the PWM pins very important and very short supply, thats why we need this for PWM purposes only.

And see the lower right corner... it says "ANALOG IN" Im not sure you can use it for controlling too...

So going back to your pin assignments above...
Powerhead relay can be assigned to non pwm pins and not pin13.
Pin1 i believe cannot be used and its reserved


Let me show you what i did on mine.

Pin0 - reserved
Pin1 - reserved
Pin2 - relay1
Pin3 - Blue LED driver (PWM)
Pin4 - LCD
Pin5 - LCD (PWM)
Pin6 - LCD (PWM)
Pin7 - LCD
Pin8 - relay2
Pin9 (free PWM)
Pin10 (free PWM)
Pin11 - White LED driver (PWM)
Pin12 - LCD
Pin13 - LCD

So right now I have Pin 9 & 10, both PWM still free for other use.

Hope this helps.

If you go for the PH probe and temp controller I would love to see it outlined here with your normal step by step attention to detail.

Thanks again for all you have done for this project.

[katchupoy]

@wardda,

If you ask me concerning lights and relay, then I can help you.... just no temps and PHs for now.

Dan

the physical relays 1 and 2 are my wave maker power heads.

I just checked back, and thanks for the info katchupoy.

I think i might just have it. " I also did Alot of google on how arduino code works"
I have been cleaning things up in the code that i will not be using for a while or at all.

So far relay 1 and 2 are on pin 13 and 12 "I changed them", they now are working, along with temps and the fan relay turns on, and off if temp1 or temp2 gets to hot, and shuts fans off at anything under 77

I have not adjusted clock yet to test the relay 4 for sump lights or my led drivers, but that is next.

my pins are now

pin 13 = relay 1
pin 12 = relay 2
pin 11 = led white driver
pin 3 = led blue drivers
pin 2 = open
pin 1 = temps
pin 0 = Moon //not installed on tank yet

pin A0/ 14 i did not use
Pin A1/ 15 open
Pin A2/ 16 Relay 4 for fuge/sumplight
Pin A3/ 17 Relay 3 for Fans
Pin A4 and A5/ 18 & 19 RTC

I found if I use the number 17 for a pin in-place of A3 things seam to work.

In the code I did a search and // a bunch of stuff like PH
All of that stuff i might try later but not for now, I'm too new to the code stuff.

But so far I like the scroll screen option.

One day I might play around and learn how to make a menu option for effects on demand.

I will let you know how everything works out if the other relay for sump light and Led stuff works, I have the full day to play around with it and finish things off.

here is a pic of what i have so far, sorry a little fizzy

[katchupoy]

Dan,
what pins are you using for your LCD? Thanks.

[Dan_Cochran]

LiquidCrystal lcd(8,9,4,5,6,7);



i did not need to wire any of that lcd stuff.

across the top it said 13,12,11,3,2,1,0 open

bottom all the power pins, then No A0, but A1,A2,A3,A4,A5 open

[Dan_Cochran]

katchupoy, thanks for the idea about the loop

My temps were froze at 185 after i pluged it back in from adding more cords.

this is what i did.

PHP Code:



void loop()
{
  onesecond();
  relay2();
  relay1();
sensors.getTempFByIndex(0);  // I added this in the LOOP 


so far it works, but if it don't, i think it is on the right track

[Dan_Cochran]

katchupoy, i tried your 2 min led run threw, Post #235

everything works.

My relay and outlet box is not done yet but everything is wired up, tomorrow i should see my led's running off from my arduino.

I don't have anything mounted in my stand yet, but with any luck it should be done tomorrow.


Me and my wife was talking about a switch to bypass the pwm, but later on this week i might look into what kind of code i can find that might allow me to turn lights on 75% or something from using one of the buttons, Just in case I want lights on for a min or 2 after hours, "new frag or something I bring home at night"



For anyone just visiting this thread, There is Alot of info in these 50+ pages.
this is where I got 98% of my info. Take note's as you read them and print the how to wire pics, it will help out Alot when build time comes.
But that is just how I did it.

katchupoy, One Big Hi-Five to you! And everyone else, even the people that only asked questions " it saved me time of asking "
