Title: Pull-Up Resistor - N00b Question of the Day.
Post by: silo_xtreme on February 18, 2008, 10:51:08 PM

Hey Everyone,

what does a pull-up resistor look like? Or if I pull something apart, how do i know if it's a pull-up resistor?

 If someone can point me to a picture, that would be great! -- maybe my google searching skills are lacking.

any resistor can be used as a pull up resistor !  :D

what is does is make sure that a pin is not floating , and pulls high ( logical 1) the pin
