      @Travis Skyler thanks so much for your reply. I got to the site thru google and I'm trying it out now.
      Looks like it's gonna take quite some time so I will get back to you later when my account password hopefully is recovered.

    अरे भाई एलईडी को बचाने के लिए कितने ओम का रजिस्टेंस लगेगा

    • @unveiltechnology4882
      @unveiltechnology4882  Před 4 lety

      If you use 3 to 4 volt battery then you have to used 1kilo ohm resistor to save the LED light and in this case this LED approximately 3v

      LED में 1k का रजिस्टेंस लगाया तो उसकी रोशनी कम हो गई और नहीं लगाया तो
      दो-तीन दिन में एलईडी खराब हो गई क्या करें भाई

      How much voltage are you used in that system ?

    • @unveiltechnology4882
      @unveiltechnology4882  Před 4 lety

      And what is the maximum voltage caring capacity of your led light?
      If these thing are not appropriate in this system then this kind of problem will be occur...
