I have a newbie question....
I've got an LED that looks great when I test it with a 3v button cell.
But in builds, we use current limiting resistors to feed our indicator LEDs a fraction of this to glow a bit, and in general we want them to be far dimmer than they are capable of. However, I want to use my LEDs to backlight stuff cools shiny glass beads and fake pyrotechnics (joking) and get as much brightness out of my LEDs.
If I've got a 9v supply, why isn't there an easy way to just give 3 of them to my LED to get full brightness rather than a 690 ohm CLR that gives me about 2 volts?
