I've got an SMT Resistor here from a cell phone that says 681 on it. Is there anyway someone can tell me exactly what this is and where I'd be able to purchase them?
So far I've gotten the concept of it controlling the amount of power going to the LED it's connected to. I guess what I'm curious to know is what resistors would I use to brighten or dim the LED. Any explantion of how I figure this out would be great.
