Week 3

This week an issue came about that an Arduino board and a pulse sensor was not enough to make the heart rate monitor. To resolve this issue a breakout board was ordered to help in coding the Arduino board and make it easier to get all the coding needed to program the target heart rate portion of the prototype. Second issue was dealing with which lights and batteries would be ordered. Batteries have two options, they can either be charged or they can be ones that could be replaced. Because the wristwatch with the heart rate sensor would be so small, the batteries in it need to be small but also powerful enough to provide the lights with enough energy.  The link for both parts are linked below, as well as pictures.
