i want to make a LED light source, I have found a few on other places, but not sure of those. I have a 9v battery, 4LEDS. If anyone would be so kind, I have two set ups I am considering. One will have a 555timer, to make the LEDS "pulse" The other is just direct connect battery to LED i am aware a resisitor or several are needed for this direct arrainagement, so my question for this setup is how to make the most of it. a third option is to incorporate the two above. *did find an instructable which used a wall plug as the driver, with some modification of course. thanks in advance.
