Hi All
I have a probably rather embarrassingly simple circuit question which I would like to ask. I am considering building some LED clusters to use as indicators, side lights and brake lights on my motorbike engined kit car project and would like to test a simple 9 LED array to test the brightness and effectiveness.
I have based my circuit on using three sets of three LEDs in series using a 220 ohm resistor and 12v supply. I think these values are ok, but I want to build it on veroboard and am unsure whether I need to use one resistor between the voltage and the three series circuits or whether each one needs it's own resistor. I have sketched up a quick diagram of the two options I am considering. The orange strips are resistors, the black strips are connecting wires and the circles are LEDs.
Can anyone give me their advice as to which circuit will work best or if I've completely screwed up!
Many Thanks
Dan
