The reason for this project. My daughter Haley is going into the medical field. While she is in college, she is working full time at a cardiologist office. I thought it would be such a fun idea to make a device that would physically reflect a person’s heart rate. I decided on the color scheme to be very kid friendly, I have to assume a child at a heart doctor’s office is a very scary thing. I am hoping that this fun simple project will comfort some kids! ?
