Its a very exciting moment.
Julia and I have been trying to apply the variables for heart beat (that was prewritten in the example codes) to work with a simple image, and after battling with Processing and Arduino for what seemed like a lifetime, we finally got an ellipse to beat.
May not seem like much, but when you put the sensor on your finger tip and hold it tightly enough that you can actually feel the pulse in said finger, you'll realize its perfectly in sync with the beating circle...give or take.
The first success was too slow, so we sped it up for the second video which was amazingly accurate in the participant keeps sharp movements to a minimal. (Shaking the sensor gets it to lose the beat because the pulse sensor is programmed to look for a rhythm so as to keep out subtle movements as a "heartbeat." Due to this, too much motion tells the arduino that its not a heart beat-which is a good thing or it would be picking up your breathing more than a heart beat.
