Hi,
Im in the mid of doing some leds projects for my car. Just wondering can I just connect a 1k resistor to the leds and connect it to the door lightings, so that the leds would light up when I open the door? Would the 1k resistor help to light up the leds?
Cheers!
Attached is a circuit I made for my UV box... it's a bit bigger than you need but it will give you an idea of how to do it.
Thank you! What's the value of the resistor that you are using? My supply is 12V from a car.
Cheers!
By the way, can I tap the LEDs to different ground from the source that I am tapping from, which means, I just take the +12V from the source but for the ground, I just tap to any grounding point in the car. Would this be alright? Any problems?
Cheers!
The problem now is that I do not know the forward voltage and current of the LEDs, I manage to found them in the attic and so decided to do something to my ride. I tried testing 1 of them with a 560ohms resistor on a 9V battery, initially able to light up properly and bright enough, but after awhile, the LEDs just blown off.
Cheers!
