Duy tran / Mbed OS BLE_Bike

* This is the code for "BLE Device for motorbike". The device is attached on any bike at will. * User can control 2 switches and these switches can control anything that user wants ie: turn on * the bike, turn on the alarm system of the bike, turn on the light... * Temperature sensor is also included in the device. User can view the temperature when he/she gets * near the bike. * For the next version, humidity and air quality sensor are also added.

Dependencies:   DHT22
