The orange line of the PSU was 3.3V, so is it a good idea to link alot of LED with 'selari' arrangement on that line? This way might save the hassle to put on resistor... (if I using 3V LED)

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... smile.gif

so the 12 v power is from PSU? or from other source? coz after i think... the PSU will get overload if i put 25 leds... will it blow?
