5V/12V LED's - Any need for a resistor?

Mice don't pop, they breed.  ;)

I guess I had the description wrong or whomever passed it to me passed it to me wrong. Worked well enough as a learner to mate resistors to LEDs.  ;D

Heh.  I made that up (at least I thought I did) and printed it in the LED-Wiz documentation.  It wasn't meant to be terribly technical, just provide a simple way to characterize the behavior of an LED compared to something that most folks have had some experience with.

MonMotha is "the man" if you really want to know how they work.

Well, it's still perfectly valid to say that if you feed your mouse (LED) too much, it'll pop.  Just that a goldfish (light bulb) will do that, too.  The difference is that while the goldfish takes what you offer, the mouse runs right past you and cleans out your pantry if you offer it a few extra crumbs.

It's probably where it came from. I'm pretty certain I don't remember what I heard/read 100%. I had to struggle to remember what goldfish had to do with LED's and had to piece together the saying from scraps that I could recall.  :dunno

Everything before 1996 was an educational ---smurfing--- nightmare anyways.
