Re: Decorative LEDs?
demosthenes: It's supposed to be a decoration, generally meaning "it's supposed to look pretty."
MrWibbles:
I don't think you'll run into problems using blue LEDs, but other colors may throw off people's vision systems. You say they're not that bright, but do remember that robots are looking for something that reflects a good deal of light. Anything that gives off light has the potential to be bright enough to throw off a vision system.
While people using HSL are probably not going to have much of a problem, people using RGB could be thrown off by red or green LEDs, or LEDs of any color with a red or green component (purple, for instance, contains red). I suggest you test to see if your camera picks up the LEDs as the vision target. If so, don't use them.
