Group 106-11

This week we rushed to get the device to its final stage. We worked on making the circuit smaller and fitting all the components tighter. We have now incorporated Arduino Nano and the sensor into one die of a circuit board. We have fitted all the components together and made it as compact as possible. The power issues we were have with Bluetooth before has also been solved.
The circuit is now very stable with the 9V DC battery power source. We have also incorporated a 3.5 mm audio cable for  plug and play capability.
On the software side, we are transferring the Processing code to Arduino code so that the heart rate calculation is done on the Arduino and doesn't require a computer. The Arduino will then broadcast the result via Bluetooth.
For the Android Application, it has been setup to receive Heart rate in Beats per Minute from Arduino via Bluetooth.
The Project is almost complete. We will be looking into the aesthetics of the design next.
