Hi... i need help on making a LED circuit..
i planing to use 1 molex connector n use a board to connect all the LED together... is tat posible?
help me all the Sifu!! thz

hope this will help..

if i put the resistor jus after the 12 v molex there mean i jus put 1 resistor at the begining.. will it b ok?

Yes,but different quantity of LEDs different ohm .

ok..let's say 10 LEDs what is the resistor i must get?

errr can show some real pic

jus put 470 ohm resistor at the +ve of led each..

what is the name of the yellow thing?
so hw many LED i can connect from a 12 v or a 5 v molex connector? 20?

yellow thing is called heatshrink.

tks bro ... ....issh wan do laa but whre TS yaa

the led that u use, how much is the voltage?

normally is 3 volts LED... but i think you can get different LED with diff volts...

EDIT: i ever tried connecting 3 LED's and stick under my CRT (looks cool but stupid idea ).... i used resistor for each LED and i chose the 5V molex power.. my LED works well and didnt burn at all.. just to get suitable resistor if you use 12V...

ok, but its hard to find led blub in kuching, any1 can tell me where to find the white n blue 1? i saw 1 shop selling white 1 for RM3 per bulb, dam exp..

haha.. then i think wan 2 export LED from here to kuching there.. wan do business v me? be partners.. lolz..
^^

btw... is there any ideas on how 2 make the LEDs in a line? there means i put 1 line on top the interior of the case...
any pics?

u connect it in series of paralle?

huhu wan do it but can it use at casing maa

hey guru, lets say if using 12v power supply, have to add 470ohm resistor before each LED or just 1 resistor for whole circuit?

If we use super bright Led then 12v won't be a problem right?

ya, super bright led bulb wont how, just connect to the yellow cable in molex connector... but got hot easilly or not that 1 i dunno.. any 1 wanna try?

i forgot which resistor i used for the LED but i know that im connecting it using parallel circuit... i've tested another set of LED which i didn't add in the resistor but connect in series to the 12v power... its 4 LED's in a row... as what we learnt in physic, voltage divide in series circuit so 12v divide by 4 LED's, each LED gets 3v of current... i've tested this and my LED does not burn after i used for half years...

ok to make it simple, i found this guide on the internet and might help every1 regarding LED questions
