LED Array Diagram

Can someone help me out a bit if they have the time, much appreciated.I wanna create an LED array on a pin board. Problem is I don't know how. I know how to solder, and know it won't be too difficult but here is what I want.1) How to wire multiple LEDs together so they lightup the same?2) How to get the LEDs to work on dual intensity (i.e. like a brake lamp where they are half intensity and go full)? I know this would require a resistor or something but any help is appreciate.3) How to wire it up to a 3 wire system (ground, park, brake)4) Possibility to do 2 different sets. One set runs off the park lamp power wire at half intensity when on. Then the others are wired to the brake lamp wire so they are off and illuminate at full intensity when braking.I like option 4 the best cause it would seem to be the easiest and most direct. I would need a resistor for the LEDs running on park so they do not light up too bright, then the others can be wired in with the right resistor to handle the brake lamp voltage and come on brighter.

These are the things that I've been thinking of while I wait for all of my pieces to fall together. I'm going the microprocessor route bc I want to do some funky stuff with the lights. Since I have no current experience with microprocessors, i don't know this for sure, but I'm thinking that I will be able to input data to decipher between the current rcvd and transmit accordingly so that way I will still have all of my LEDs available and it (the mp) will dictate the output and therefore the brightness. You should probably try oznium's forums. They are no GenVibe, but they def know their LEDs. I know I'm going to be relying on them and my dad (30+yr electrician) when it comes to troubleshooting my way through this.So what made you change your mind from the pre-made setup to running the custom method?

I aI already started posting there. I was in email talks with superbrightleds.com but they seem to be uninterested in helping me anymore.

I've got a link at home of a decent little explanation of wiring the leds and such at home. Once I get there I'll post it for you and maybe that can at least give you some kind of help.

i assume you are trying to take the brake bulbs and change them to LEDs. as i'm looking at the wiring manual it looks like there are actually 2 lines leading to the bulbs which leads me to believe there are either 2 bulbs or 2 filaments in them. i think you can wiring something up so that for the parking lights you use a lower intensity LED and then for the brake lights you can use a higher intensity LED to illuminate.i'm not positive because i haven't had to change the brake bulbs yet. i'm also unsure of the voltages that are sent to the bulbs. depending on the voltages and current it can change your wiring and LEDs used.

Yes, it is a dual filament bulb. Here is the link i talked about earlier. It does include some basic stuff, but the videos cover everything from the very beginning to the end. Link You could run two different intensity LEDs as tribleman stated connected to each specific case, if since the LEDs will react to the current being supplied, you could be able to just use all one kind and intensity of LED as well. This, of course, leads into what was mentioned earlier about the microprocessor. I'm wondering though if there is a way that if the leads off of the brake and running light can be tied together (after the resistor) since the brake essentially overrides the running light. In theory, running light is on, through resistor, once brake hits, it is considered the live wire and will thenpump that current through.Pretty crappy drawing but I don't think I explained it all that well above.

Alone led's will not be able to do that. You need something to sense which line "brake, reverse etc." is being requested then powering the led's to that specific level of voltage. this could be done with a microcontroller. or if you got tricky with voltages and switches you maybe could...ugh I havent done this stuff in years Im rusty as heck.

So you think wiring them so they all are low then all go high is the easiest?I was thinking that #4 would be the easiest, finding out which wire does what is easy, cut them both, connect one and turn on the lights. If the light doesn't come on try the brake pedal. Then I can find out which is park and what is brake and wire in the LEDs accordingly. I'm still beginning with the whole winter ahead. I'm going to Radio Shack today to get a board and some LEDs to play around with design first. Cut it to shape and see what looks best.

easiest is 4 yes, one set in parallel to do one thing and another set in parallel to do another.If you do go to radio shack, only use their parts as research. if you end up needing led's for the final product please get nice led's from a online store..I can find my receipt from where I bought my last ones... RS's are pretty cheap and there are much better ones out.

I was gonna use RS as my template since they are cheap, then make the real ones using the Oznium LEDs .29 each.

sounds like a good plan. RS's leds arent cheap but they are cheap quality..incase you blow them up
