(Another) DIY LED Controller - Simple Arduino Style

muda · Aug 13, 2011

24V psu used for powering leds is moved from pin2 to A1, if you noticed. Also possible other modifications . Please study it before use.

Muda,
I don't understand why you have the tank temp sensor in with your heatsink temp sensor to run the heatsink fan.And in order for the moonilghts to run the moonphqasesyou need to remove the following code:

Code:

/*||||||||||||||||||||||||||  D E F I N E  :  M O O N  L I G H T  O N - O F ||||||||||||||||||||||||||||*/

void MoonOn()
{
  digitalWrite(moon, HIGH); 
}
void MoonOff()
{
  digitalWrite(moon, LOW);
}</pre>

and add

Code:

/************************************************M O O N P H A S E S ********************************************************************/
int iBlueIntensity;       //declare the integer of blue intensity
float fBlueIntensity;       //declare the floating point version of blue intensity

to your definitions as well as remove the MoonOn(); and MoonOff(); out of the loop.

Thanks Martin,

I still dont have moonlights setup. Ill fix this part by your recommendations. Was too lazy to check before.

My LEDs are on passive heatsink and dont need cooling. If tank temp rises too much (hot day), then I need to cool both - tank and leds. This way tank temp reacts faster.

Also one small problem is with displaying 24V to LCD. Sometimes "2" is disappearing from display and I can find what causes it. Seems like overflow from line 1. But why ?...

liquidarts · Aug 14, 2011

So I looked over your code and saw there was extra spacing in the lcd.print(" "); lines...that may have been your problem.I fixed your code hopefully so copy and try it out and let me know if it works out.Because on paper all the character placement seems to be correct.But if it sill cuts out try moving the b: and w: info on line 2 to the left by 1 or 2 spaces.

Code:

Not the case. 2 is disappearing during ramp up and down. While max, or night time its ok.

I wonder if "lcd.print((whiteercent*99)/255); " can bring more than two digits anytime ? I intentionally used 99 instead of 100 for this purpose. My idea was, that it can maximum be 99, as whitepercent is max 255. But who knows what arduino has in its mind...

I'd try moving the light temp over one then...I know it fixed my problem when I had it

muda · Aug 15, 2011

Thanks for suggestion. Seems like its the only option left.

I did it. 128X64 lcd mega arduino sketch.

I did it. 128X64 lcd mega arduino sketch.

Well it took me a week to learn how to write a sketch, and be able to figure out how to incorporate a 128x64 KS0108 GLCD into a Katchupoy original sketch.
Thanks for all of your guys hard work, especially Molehs who was able to give me a push in the right direction on working with a GLCD.
I felt I had to get this working so I could contribute to this very informative thread, and I hope someone could use this.
I almost gave up on the GLCD, but I just had to have all that extra real estate to be able to play with bitmaps.
Well its late and my kids are going to wake me up in a couple hours, I will have pictures and updates shortly, so goodnight.
Maybe tonight I will be able to dream about something else other than sketches for my arduino.:spin2:
PS the ramptimes are set to 2 minutes for testing purposes and I set the blue white display to show percentage 10%-100%.

Sweet....would love to see how it turned out and how much room you have left on the display to be able to show more readings.

Please do not abuse me for the wiring job, I did this at 3am.
More pics of the whole setup on the way.
Thanks again guys, would not have even tried to attempt this with out the headstart you gave me.:bum:
:celeb2:

Very Cool.....because you mentioned something about your GLCD I dusted the one that came with mine off to play with too....remember to add your info to that sketch....u deserve the credit.

studog86 · Aug 17, 2011

Credit, heck no.

All I did was jump on the backs of you guys and threw a couple of sketches out until it finally worked, besides I have no idea if it is bug proof, as of yet I still have not been able to test the darn thing on a full system, rapid LED stlll has not delivered my 10v regulated power supply to run my Meanwells. I used a 4 volt power supply to test the system but the dimming was eratic. Lights did not come on until 20% and the dimming cycles were barely noticeable. I hope it was just because I had a low voltage going to the pwm. I dont see how I could have screwed up the output to the pwm with the changes I made to the LCD.print.
Have fun.
I will have more pics soon.
This is not a hobby, it is an addiction.

The fastest way to test the dimming and all the other outputs is by using the 3mm LEDs that came with your kit if you bought it on ebay.....it's how I test it all on the breadboard before moving to my LED drivers and relays....I let everything run for about a week on the 1.5v LEDs though before going forward.I run both the uno and mega on 9v 1A wallwart.

Thanks for the advice and I would do that if I wasn't changing the diaper of one child and putting back together my arduino that my older child just took apart. My power supply is supposed to be her tomorrow, so I am going to wait until then and post back my results.

"I know just enough about electricity to be safe or extremely dangerous."

The Arduino is a buggy beast but packs a huge punch for what it can do for such a small package, I will just keep chuggin alone until I get all the bugs figured out, or until my wife kills me.:deadhorse:
Cheers! Now back to the Vino.

I think I found the problem too much Vino and coding are not a good mix

Do you remember this? This is the original wiring diagram "with pot" and without Arduino...

Well the only change we will do with this wiring is to "tap" or "cut" the negative side from the "10v" signal going to the LED driver.

This diagram is only for one channel and for one Arduino pin. It means 1 ramp up and down. One channel can have 1,2 or 4 LED drivers connected to it, but this only means that all of them will ramp up and ramp down at the same time.

If you need to put another channel, example... white, then you just need to duplicate the wiring, resistor, transistor and use another arduino pin.

So the way I understand it this diagram is good for both the "D" and "P" type drivers, just wanted to be sure.

Also, is there a simple code I can enter just for testing purposes of the LED, most importantly the max value so that I can dial in the max current for each string as I go.

I had asked before, and don't think I got a definitive answer one way or the other, but right now I have 96 LEDs which ideally would be 8 drivers. Will a two channel arduino setup be able to handle that many drivers? Will one 10V supply be good for all of the drivers?

Man gotta lot of work ahead of me, and it's all just sitting here laughing at me haha.

liquidarts · Aug 18, 2011

int blueramptime = 60 ; <-----change to under 10
int whiteramptime = 180 ; <-----change to under 10
int photoperiod = 240 ; <-----change to under 10
int ontime = 11 ; // time of day (hour, 24h clock) to begin photoperiod fade in

TheFishMan65 · Aug 18, 2011

BigCity,
The recommended ELN max is 8. So I would look at the HLGs.

BigCity · Aug 18, 2011

Yeah, unfortunately I got the kits from rapid so I have the drivers on hand already, I may look into driving 2 parallel strings to try to cut down the drivers a bit. I have way more LED's than I need and was looking into running them at a lower amperage any how to allow for any future upgrade on a larger tank if needed.

Yes

Make sure that you have the 10v supply first then dialed in your SVR2. Then only then you can do the max current for each.
