Amit and I spent most of today working on our presentation, and we came out with two awesome diagrams explaining the carbon monoxide and respiratory rate sensors (which I unfortunately don't have on my computer but they look really good, I swear), as well as the beginning of a process/final post, which I added to the portfolio. Sam persevered with further developing the respiratory/pulse sensor throughout and after the day, as well as combining Amit's functioning carbon monoxide Arduino code with all the other sensors in a cohesive, working way.
