Connect Arduino With Bluetooth Module To Android Device

       I recently done a project with Arduino , on which i needed to communicate the Arduino with my Android phone via bluetooth interface, after referencing through the tutorials about the Bluetooth , i succeeded to implement the connectivity of  my phone and Arduino. So here am going to implement a simple example containing two buttons on the android to control the led connected in the led pin of Arduino.

   Here i used Arduino nano v3 micro-controller and HC-05 Bluetooth Module. The majority of the Arduino boards contain a LED connected to the pin 12.

Create A Notification In Android

             Here am going to describe how a notification can make on the Android. A notification is a message you can display to the user outside of your application's normal UI. When you tell the system to issue a notification, it first appears as an icon in the notification area. To see the details of the notification, the user opens the notification drawer. Both the notification area and the notification drawer are system-controlled areas that the user can view at any time.

         For creating a notification, we need two android activities. One is the activity that is creating the Notification and second activity for managing the notification if the user selects the notification from the notification drawer .Every notification containing a unique id which represents the notification, here i used the notification id as 1.  

        

         Here am going to explain this by making a Android Application for displaying a simple Notification.

The name of the Application is "Notification".
