Meanwell LDD driver: for those who want to dim to 0 using Arduino

Still should have a RTC and some sort of shield for on/off times and to set intensities via the pwm controlled by arduino. Look into heatsinks, and cooling fans which can also be arduino controlled. Kind of like,... which came first,...the chicken or the egg. I think you first need to zero in on what kind of led's your planning on using and how many, and that decision is based on what will work for your setup,ie... size, depth(optics or not), what type of corals you want in the tank ect, ect., then it becomes easier to figure the first part of the questions. Remember when you get answers to your questions, google the parts you don't understand, and if still,...no go, reask the new parts you don't understand. Its all a learning curve :p Did you look at that Jarduino manual. Even if your not interested in a Jarduino controller the picture has a line drawing that might help you understand what hooks to what. Also check the Jarduino's builder's build page, just reading it(its explained for beginner diy'ers to follow) might shed some light for you . good luck :thumbsup: ---Rick


Yes, I actually printed it out and have referenced it a bunch but I have to say that the Jarduino build is pretty high level. For a guy just starting it's very hard to look at the drawings and understand what's what. I read about half the 'dummies' book last night and that is by far been my best friend so far. Figured I'd keep reading and asking questions until I can understand what I'm looking at in the Jarduino manual.
 
I am afraid the kit you bought does NOT give you access to the Arduino pins. The ITDB02 v1.1 should have been bought as a kit, you the substitute all the pin headers with Stacking headers.
Also in my experience with the TFT screens any extension over 12'' corrupts the graphics on the screen.
Any way good luck
 
I don't think anyone minds your questions. For the most part there's not many questions on LDD's right now. Heck I had a page tied up a week ago about no picture on my Jarduino screen. lol. rott got me back in the right direction today!! Thanks rott!!
Yay Yay Yay,....now no more :headwally: its all :dance:---Rick

What was wrong with the screen eventually?
 
Short answer,...me lol I had the files on my computer all over the place, and no complete file/folder for when I was trying to upload the program to my mega. I'm not very computer savvy where rott makes his living at it, and took him over 3 hours to undo my mess :lmao: ---Rick
 
I'm getting ready to order another batch of 10V to 5V Pwm convertors this week, so I thought I'd show some of the improvements that I made to the design. I made two different versions this time around. One will be PlugNPlay to the Profilux control cable scheme, and the other to the NEPTUNE APEX. The Original design had to grow a bit to fit the RJ12/RJ45 connections, so I put both designs on the same PcB to save on manufacturing costs. Both designs fit into an area less than 10cm X 10cm. I'll just cut them in two, after they're delivered.

Let me know what you guys think.

O2,

I was looking over the manual from Neptune Systems and am wondering if you have the pinouts correct for the Apex since on my version the pin layout is different from yours.

Pin Apex RJ-45 Usage
1 0-10VDC V2 and V4
2 Ground
3
4
5 0-10VDC V1 and V3
6 Ground
7
8
 
Sorry man I don't even know the basics. I want 5 channels running 10 LEDs each. So 50 1w LEDs rated at 350mA 3.2-3.8 forward voltage. TO figure oyt total amperage would I just do 350mA*50= 14,000mA?
 
OK, I thought you posted the type and how many led's you were buying a little while back.
If your led's are 750ma or 500ma or 1a each, add the total together for starts. Oh and keep in mind that I am self taught,...so don't take everything I say as correct. lol.

And the second part of your question,...did you bring the board picture up, and scroll through the pictures? Ben the owner is really great at answering questions. Email him, hes always quick to get back

Yes, and 1A = 1000ma. So 750ma = 3/4 amp. PS's(power supply)(helps to pick up on the lingo) are typical listed in amps, unless they are really small. look at the tag on your phone charger(I usually call them car phones, but that really dates me)
