Pulse Player is a pulse oximeter and an Android-based App that allows the user to hear their own heartrate which is condusive to relaxation. The benefit of listening to one's heartbeat is greatly examined in Eastern medicine; it is often a method in tai chi, and is known to have soothing and somnolent benefits. We used this theory as the basis for our product.

The Pulse Player App is connected via bluetooth to an Arduino microcontroller. The Arduino microcontroller connects to a pulse sensor located on a finger band that captures the user's heartbeat. This is done through an LED located on the pulse sensor that when pressed against one's finger or ear lobe calculates the BPM by recieving either a 0 or a 1; 1 is a pulseation and 0 is no pulseation. The Arduino reads these numbers and sends them to the Pulse Player App which plays the heartbeat sound whenever a 1 is recieved. Lastly, we placed the Arduino and battery inside a toy bear, so it would not appear threatening and would be pleasant for young kids to use.
