Introduction

It all started when my friend and I were running late for a local dance competition. As soon as we arrived, my friend quickly exited the car and grabbed his phone. Without realizing it, he had ripped the audio connector off the cable while it was still connected to his phone. It was at that point that I decided to upgrade my sound system by adding an audio Bluetooth.
