Day_5

comment: I couldn't figure out the modifications for the homework, since I would always get 0 for my results for all of my modification. It's probably my loop and if statement making the code spit out 0. I'm not too sure on how to fix the problem, since I barely understand loops and I find it tricky working with the if statements. On the brighter side, I managed to get the RGB to display the color I want from blue, and red. So that's somewhat of a win. The arduino lab wasn't too difficult, unlike debounce which, stills haunts me.
