Raspberry Pi Class 07 - Button Input Part 1

This is from my Raspberry Pi class in the 2014-2015 school year. I filmed these at home with my own Raspberry Pi and equipment so I could share the content after the class was over. I used the videos to "flip" the class experience. My students build their projects and learned the code from videos, and whenever we have class time together, we review and make upgrades to the circuits and code.
