(Another) DIY LED Controller - Simple Arduino Style

muda said:
If you look at my version - there is posibility to change dimming the way you like. You can make any count of step and any size. You can dim blues and whites parallel or one after another . It is couple pages above.

Thanks for the respsone. I was able to put together what I wanted referencing the Arduino Sketches thread.

@ Muda: ooops.....sorry,thought you was that

i remember to have read that..... the age...:headwalls:

Perhaps anybody else can help me....

I'm seeing the same thing with the temp. I just got my rtc today an am running a sketch and see that the temp does not update when the blues are ramping. that is as far as I got testing as I just got it running a little while ago. I'm waiting on my drivers so I'm just looking at the display for testing.
 
Temp freezing

I think i´solved this little problem.
I´m using Muda´s sketch,just a little modified.
There are "while" commands for dimming like this:

Code: 
    /*||||||||||||||||||||||||||||||||||||||||||   F A D E  I N ||||||||||||||||||||||||||||||||||||||||||||||*/

 if (daybyminute >= (ontime*60))
   { if (daybyminute < ((ontime*60) + ramptime))
    {
      
      AbluftOn();
      BlueledOn();
      MoonledOff();
      MoonOff();
      Temperature();
      
  lcd.setCursor(17, 0);
  lcd.write(9); // Sonnenaufgang
  lcd.setCursor(18,0);
  lcd.write(1);
  //lcd.setCursor(18, 0);
 // lcd.write(0);
 // lcd.write(1);
  lcd.setCursor(4,1);    
  lcd.print("%");
  lcd.setCursor(11,1);
  lcd.print("%");
      int i;
      for (int i = 0; i < abc; i++)
{
  analogWrite(blue, bluepercent[i]);
  analogWrite(white, whitepercent[i]);
  
       lcd.setCursor(2, 1);
       lcd.print((bluepercent[i]*99)/255);
              
       if (i < 10) lcd.print(" ");
              
       lcd.setCursor(9, 1); 
       lcd.print((whitepercent[i]*99)/255);    
       if (i < 10)   lcd.print(" ");
       
       int countdown = ((rampup*60)/abc);
     [COLOR="Red"] [B] [SIZE="5"]while[/SIZE][/B] [/COLOR](countdown>0)
        {
          onesecond();
          countdown--;
          [SIZE="5"][COLOR="Lime"][B]Temperature[/B][/COLOR][/SIZE]();
     
          //lcd.setCursor(6, 1);
          //if (countdown < 100) lcd.print ("0");
          //if (countdown < 10) lcd.print ("0");
          //lcd.print(countdown);
            //lcd.setCursor(16,1);  // Moon
            //lcd.print("off");
        }
A friend of mine told me to insert the temperature Array to the "while" circle und temp will work.

I don´t give a guarantee that this one works,just testing it for myself.
I also hope it´s understandable.

I will give it a try also. Thanks!

My 20x4 and other goodies just showed up yesterday.:D:D I was trying the sketch with the weather patterns but can't get the temp to show. Not sure what I am doing wrong there.
 
So I pasted that code into the section you were talking about and the temp does update during the ramp up and down now. It did screw with the timing though. The count now takes twice? as long. I tried to get rid of the delays in the temp code which helped a little.

My RTC freaked out and started reading all kind of strange times and was not counting. I could not reset it even after pulling the battery. I tried a few more times and it finally came around and is working now. Not sure what that was all about.
 
Hi

I have the same problem,but i saw it yesterday evening when i was at home.
I was confused too.
Sorry,that it doesn´t work. It was a tip of a friend of mine.
Just try to get rid of this....
If you know how it could be solved please let me know.
I´m working on it,but could not understand why the Arduino do what it do...:headwally:

It does work but just messes with the fade out timings. I can adjust my fade times accordingly. :D

I still want to get the weather patterns sketch by liquidart to work. That one looks really cool. For some reason, it wont execute the whole sketch. It will only show about half of the info out. I put some lcd.print statements in the temp section and it never prints them so I guess it never even gets that far in the script. I will play around with that one some more.
 
Here´s something for you....
The same Array i use in my Sketch.
Code: 
//>>>>>>>>>>>>>>>> D E F I N E   T E M P E R A T U R E DS18B20 <<<<<<<<<<<<<<< 
void Temperature()
{
sensors.requestTemperatures(); // Send the command to get temperatures
//delay(750);
 lcd.setCursor(2, 3);//Watertemp=2
 
float temp1=0, temp2=0;  //temp1 = LedTemp, Temp2 = Watertemp
 
 temp1=sensors.getTempCByIndex(0);
 lcd.print(sensors.getTempCByIndex(0));
 lcd.print((char)223);
 lcd.print("C");
 
 lcd.setCursor(2, 2);

 temp2=sensors.getTempCByIndex(1);
 lcd.print(sensors.getTempCByIndex(1));
 lcd.print((char)223);
 lcd.print("C");
 
 if ((temp2) > 27) // Wassertemp
    {
      digitalWrite(fanwater,HIGH);
      lcd.setCursor(16,2);
      lcd.print("on ");
      lcd.setCursor(9,2);
      lcd.print("!");
    }
  else
    {
      digitalWrite(fanwater,LOW);
      lcd.setCursor(16,2);
      lcd.print("off");
      lcd.setCursor(9,2);
      lcd.print(" ");
    }
    
 if ((temp1) > 35)
    {
     digitalWrite(fanled,HIGH);
     lcd.setCursor(16,3);
     lcd.print("on ");
     lcd.setCursor(9,3);
     lcd.print("!");
    }
   else
    {
     digitalWrite(fanled,LOW);
     lcd.setCursor(16,3);
     lcd.print("off");
     lcd.setCursor(9,3);
     lcd.print(" ");
    }  
}

This one runs....exept the dimming phases.

HI

The temperature is an Array and BEFORE SETUP.
Everytime i need it in sketch only have to write "Temperature();"

You are using Mudas sketch,right?
The 24V he defined as relay for the lights as the "MAIN SWITCH",yes.

Greetings Ronny
 
ATS is algae scrubber , which I am running. Thing this is simple on/off timer.
24V is DC power supply for LED drivers. I like it to switch off at night.

In the past, I mentioned that I want to buy/build another one identical to what i had before so I can play with the sketch/code etc. So I can add features like temp, etc. And I believe, Fishman want to go along with me because he is an expert with coding and he does it for a living....

I think im going to do it soon. My ranco controller gave up and I believe i can use the existing temp sensor on it attach to my arduino. Unfortunately i cannot do it on my existing arduino setup, so i have decided that Im going to buy another set.

so here is my parts list again... this time, local US seller, and I believe cheaper than what i had before.

Arduino + 16x2 LCD + misc items = $40

DS1307 RTC = $9

5v Relay Module $10

if you dont want the combo kit above... you can also go with these...

Arduino $23

20x4 LCD $13.50

8 channel relay board with 5v coil. $16.75

That shield with the breadboard will be nice for testing and you can solder it up when you are done. i got the soldering one with the screw terminals for each of the pins. Starting to assemble mine now. I went with the 20x4. The extra room is very nice but wish i would have gone with an i2c version. Cant wait to see your new version. :)
 
Hi guys!
I wanted to start the very same project until I found out that you guys already did all the work for me! Amazing work guys!! Thank you!
There´s one thing to add to your setup:
I thought about the 10v issue and came up with a MAX680 voltage doubler, which might make life more easier, taking the arduino´s 5V and make it 10v for the PWM signal.. Does someone have an idea if this might be useful?
http://datasheets.maxim-ic.com/en/ds/MAX680-MAX681.pdf
problem might be that it only has 500uA supply current. will this be enough?
 
Hi @ All!!

@ yellobello: only for Arduino with its relayboard and,or for Dimming the Drivers it would be strong enough I think. If you use Fans for Watercooling,Ledcooling,etc. I would take a stronger one,about 2 Ampere will do it.

@ All: I plan to dim red Leds for Sunrise/Sunset too if blues and whites are already dimming in/out. I only want them in the dimming phases. Info: I´m using mudas sketch if this is helpful. How could this look like?
This is the dim in:
Code: 
   /*||||||||||||||||||||||||||||||||||||||||||   F A D E  I N ||||||||||||||||||||||||||||||||||||||||||||||*/

 if (daybyminute >= (ontime*60))               // Anfangszeit Fade in , (aktuelleZeit >= (Startzeit*60))
   { if (daybyminute < ((ontime*60) + ramptime))          // Endzeit Fade in , (aktuelleZeit < ((Startzeit*60) + Dimmzeit))
    {
      
      AbluftOn();
      BlueledOn();
      MoonledOff();
      MoonOff();
      Temperature();
      
  lcd.setCursor(17, 0);
  lcd.write(0); // Sonnenaufgang
  //lcd.setCursor(18,0);
  lcd.write(1);
  
      int i;
      for (int i = 0; i < abc; i++)
{
  analogWrite(blue, bluepercent[i]);
  analogWrite(white, whitepercent[i]);
  
       lcd.setCursor(2, 1);
       lcd.print((bluepercent[i]*99)/255);
       lcd.print("%");
              
       if (i < 10) lcd.print(" ");
              
       lcd.setCursor(9, 1); 
       lcd.print((whitepercent[i]*99)/255);
       lcd.print("%");    
       if (i < 10)   lcd.print(" ");
       
       int countdown = ((rampup*60)/abc);
      while (countdown>0)
        {
          onesecond();
          countdown--;
         // Temperature();
          //lcd.setCursor(6, 1);
          //if (countdown < 100) lcd.print ("0");
          //if (countdown < 10) lcd.print ("0");
          //lcd.print(countdown);
          //lcd.setCursor(16,1);  // Moon
          //lcd.print("off");
        }
       }
     }
    }

I´m sorry that I´m not able to do it myself,I´m just a newbie with Arduino.

best regards Ronny
 
The arduino will be driven by 5V, but i just wanted to make 10v out of the 5V for the sole purpose of having the full 10v on the pwm signal.
I made a quick and dirty diagram where the meanwell is a peltier element. :-)
Could someone pls check if this could work this way?
g6o44ni2.png

The solution with the 4.7uF caps comes from the datasheet of the MAX680, but the pin layout of the datasheet seems to be incorrect (C2+ seems misspelled as C1+).. could someone pls verify this?
Also, are the diodes I put in really necessary? I am a electronics noob..
