how can i make a matrix led white modules, so that it can pe powered from a car battery [12V].
what amount of resistance i have to connect?
i think i have to connect 3led modules & 470 ohm resistance, all in series to light up by 12v battery.
+--=--@--@--@-- -ve
diagram above & below--
@ is taken as led module..
= is taken as 470 ohm resistance in series.
then repeating this combination i can make strip with any no of columns likewise (15-20 columns & so on). all these repeated combination's is to be connected in parallel to each other.
@ @ @ @ @ @ @ @ @ @ @ @ @
@ @ @ @ @ @ @ @ @ @ @ @ @
@ @ @ @ @ @ @ @ @ @ @ @ @
= = = = = = = = = = = = =
plz tell me either i am right or wrong. any other combination working with 12V battery is welcomed. plz provide link to any diagram if available for such combination.
thanx in advance
