This was a very nice project that I got to also see in person. I love the idea of reading a human pulse for the emotions project because heart rates can change based on one’s emotions. In terms of showing motorized emotion, I didn’t really see much motion. For future reference, you could actually make a servo operated meter that shows a range of Beats per Minute. The servo would move an arrow to the corresponding pulse in real time to show the person’s heart beat. This could be done by using basic data transformation to convert the BPM to the servo’s angle position.
