Thread: how can you tell if your LED is burned out?

  1. #1

    Default how can you tell if your LED is burned out?

    i'm pretty sure i've got this wired up right. i'm using a hasbro sound card, and the sound turns on when i hit the switch, but the light wont come on.

    So i took the LED assemby off, and tried to direct wire it to the 4 AA's, just for a second to see if it still works, and nothign happend...

    yours is blown. if it wasn't already dead, wiring it to 4AAs with no resistor, it is now blown.
    are you sure that ya wired red to positive, and black to negative? that's happened to me before

    If you want to test a led use a 3 volt pack, it won't fry the led.

    nono, its ok.

    i think the wires were just loose. I replaced them with a heavier gauge wre and just tapped the connections together for an instant. It's not burned out.

    i thought you dont need a resistor if your using a hasbro sound board?

    I'm looking at this diagram:

    and am I right that the positve from the battery has to go to the positive on the LED and the sound card at teh same time?

    this is just not my day.

    i got the wiring right! So i start putting the guts back into the hilt, and the wires snap off the battery holder! so i go to solder them back on, and i melted the plastic under the contact off.

    i hope radio shack has the size holder i need- i want this saber done befor the weekend

    Putting an LED on a 4AA pak for a brief moment wont fry it(i wouldn't recommend making it a habit)....it isn't like an incandescent bulb....if you leave it on it will though...the heat will fry it.....but just a touch to make sure it still lives shouldn't bother it....

    Edit: Cern....it has happened to all of us.....it gets better....

    I haven't burned out any LEDs yet, but I've replaced a few broken battery holders in friend's sabers.
