Ernest Williams / Mbed 2 deprecated Bluetooth

The purpose of this project was to create a system that would allow users to monitor a locked device using a Bluetooth device. This Bluetooth device will show the last user that unlocked the device, and also allows the user to unlock the device using the Bluetooth device. This device can be physically unlocked using a capacitive touch keypad sensor.

Dependencies:   mbed Motor Servo
