Week 7

A few adjustments were met to complete the design of the heart monitor. The first change made was the placement of the pulse sensor. The sensor is most efficient when it is placed at the thumb. The idea will be as shown below:

Deciding what batteries to use was a huge hurdle because the decision of whether the batteries should be rechargeable or not was a big part of the project and it make sure that the batteries were going to be enough to power the entire monitor. We decided to not to rechargeable batteries and stick with the cell batteries that we would make the user change whenever it ran out. A proper holder for the batteries was needed so we ordered, the links for that arec below. Another revision was made to the lights, we decided to do was change what the lights represented. Yellow means barely working out, green means in target heart rate, 2 greens means working hard (really good), and read means over.
