Pulse sensor: iteration 1

For my first use of the pulse sensor and its accompanying code, I created a heart as instructed on the pulse sensor website and embedded my arduino uno board inside it. I then powered my board with a 9volt battery. Performing this task allowed me to gain a feel of working with fabric as I have never worked with fabrics or sewing before. While doing this I also learned that the fade loop within the code actually disrupts the pulse sensors count, and the pulse was not accurate until this bit was commented out. In my next iteration I plan on creating an additional plush toy with additional circuits using more digital pins on my arduino uno board.
