onesky:
cool
i just started the same project
i wish to setup a saber with 4 strings of 14 parallel linked round leds, for a total of 56i bought leds with 25-30 angle degree 5mm 20mA 3.0-3.4v (couldn't find with 45°, the best choice for sabers)

i have seen the driver linked above: how to link it to the string and to the digital pin of arduino? we need a transistor?
Yes, you will need transistors to turn the LED's on and off. I've been doing some research on the LEDs, and the brightest LED that I found was a green one with a Luminous Intensity: 6000~16000mcd.

I really want a red or blue saber, but I haven't been able to find any LEDs that come close to the green LED's Luminous Intensity.
