Help with LED project?
3 years ago
General
So i decided to work on a fairly ambitious project (for me anyway). I decided to 3d design and print a modular display for standard sized Hot Wheels/Matchbox/etc vehicles. The 3d design and printing seems to have gone well, and I've got a display mocked up that will hold 144 vehicles.
Now comes the hard part, figuring out how to wire up the LED's. I've never done anything like that before so i really need some help figuring out how to set the LED's up and so on. I've looked online and tried out a few calculators, but I'm not sure the ones I've tried are really for anything with this many LED's.
I bought two different types of LED's and a AC to DC power source (stats posted below). I'll only use one type of the LED's, i got two to experiment a bit with and see which type worked better. One's a micro LED with wire leads attached, the other is a small LED unit I'll have to solder wire to. The power source i got, had an adapter that had wire connectors on it, so i can just wire everything up easily once i figure out what route I'm going. I also have some resistors that came with the micro LED's, but may need to order different ones depending on what sort of setup i end up building.
the current setup for the display is 12 units by 12 units. Based on some of the calculators I've tried, one of the recommended setups is groups of 4 LED's in series with a 1OHM resistor, with those 36 units then wired in parallel. Hopefully I've used the terms there correctly :P
Again, i have very little experience with this type of wiring, so maybe the items I've already picked up aren't right for the project I'm trying to do, if they aren't, what alternatives should i look at?

Anyway, thoughts, suggestions, etc would be welcome!

you may jsut need 1 10ohm and put them in series, or,
[positive+LEDa-LEDb-LEDc-LEDd-Resistor -neg]
instead of parallel
{+LEDa-Resistor-}
{+LEDb-Resistor-}
Positive+{insert all here }-Neg
{+LEDc-Resistor-}
{+LEDd-Resistor-}
your Power supply shoudl be WELL more than enough to power them all in series, all you'd really change is the requirment of leads/wires to connect them
I also looked at those pre-wired "fairy light" strings you find in most craft stores, which was another option i was thinking about.
Doing all the LED's in series, with the one resistor is definitely tempting, and would probably be the easiest/quickest option to go with. My main thought though, was a combination of series and parallel, that way if one LED goes bad, i don't have to search through all 144 to figure out which one crapped out :P
Good to know that i should be able to hook all the LED's up together and only use 1 resistor with eh power supply i have, if i go with a single series circuit!
Thank you!
make Blocks of them so,, Series A Series B, erise C, ectre, liek a folder heirarchy, to keep an easier track of what is where,
I also HIGHLY recomend gettign a breadboard and some jumper wires to test those patterns, before you start so you knwo what will work and how to most breadboard testign kits will not be more thna 50$US. and might even come with Discovery kits to help you pick up faster
