Electronics 201: Pull-Up and Pull-Down Resistors

In this Electronics 201 lecture, we talk about the useful tool that is the pull-up and pull-down resistor. We also go over the concept that is the tri-state buffer. I'm looking for suggestions for future videos, so if you have any topics, just put them in the comments below. As usual you can check out my blog at http://8bitprojects.blogspot.com/
