we know we wanted to use anArduino as it was waht was available to us and also because we already had a type of basic understanding of it before the start of this project. We started off by simply coding a LED lighting up a the press of a button. 

Once that worked, when did some research and ordered the bluetooth extension: TTGO. This enabled us to put in the counting calculation we needed in our project. So we re-wrote our code and while connecting the device to one of our phone we checked if the code work and resolved any problems we had. one of the problems was static electricity connecting 2 of our wires and giving us false results.
