Does anyone know how to hook up leds? i recently purchased 100 White LEDs and resisitors for a project but decided it wouldnt look good. So im looking for ideas for the use of it and if you are in the area, i can definetly distribute some for free if you can use some for a project you had in mind, its no problem.

the specs are 5mm White LEds
Iv 15,000 ( i believe is the mdc)
Vf 3.2-3.6

far better then the ones you buy at radio shack.

 

To hook up the LED's all you have to do is attach the long leg of the LED to one end of the resistor and the other end of the resistor to a red conductive wire (RED). The other end of the LED attach to another conductive wire (BLACK). Hope that helps.

 

can i use multiple leds with one resistor or does each one need its own?

hey are you the guy that went to polytechnic Univ.? i think i remember your car from the ross dock meet.

 

I guess you should be able to if you run in them in parallel with each other.

 

For white LEDs, hook up three LEDs in-line - long leg of one to short leg of the other, etc - and then add a 150 ohm resistor at the end. Oh and in general, if you can't find the resistor just bump up to a slighly higher resistance (eg: 168 ohms I think).

If you ever wanna play with different LEDs, all you need is the forward voltage (in volts), forward current (in milliamps), and your source voltage (eg: 12V for the car). Then use a "LED resistor series" calculator like this one:

i give up lol. :surrender i just dont have anymore time and this is reminding me of college. But thanks guys i appreciate the help, i'll keep that link handy

 

Don't give up! It's really really easy. You just need the 150 ohm resistors from radio shack and then connect long leg of one to the short leg of the other. It really helps if you get a circuit board from Radio Shack or online (ebay).

Here's a pic to get you motivated! Each row has one resistor to three white LEDs. They're for the dome light of my other ride since there aren't any LED bulbs that fit.

 

it is really easy i used superflux leds and used 10 for my dome light brightest dome ull ever make

but if u dont need them ill take 40
