@nomad... just make sure if you are using the signal pin to supply power to those leds, that they are not pulling more than 20mA (edit correction that is 10mA not 20mA) or you could damage your digital pins... The digital signal pins cannot supply that much curremt....
You would want them in parallel not series... Well if they each pull 1mA then 8 in parallel would be 8mA.... If you put them in series you'll need 24V to power 8 Leds at 3V each...
glad to be of service

i read here the manuel off the leds.1Ma 3 volts. thanks for the warning.
@nomad... awesome, you're good to go then...

what would be the Ma be from 8 red soft leds in serie?

wow.so parallel is all separt? i have to use 8 ports to?
no... parallel is all on one pin.... see picture for both series and parallel circuits... First picture is series...
