Smart Home Energy Management System Using Arduino

 
4.1 interfaces implementation:
Front window: This page will allow the user to connect the Arduino with the application. 
Afterward, the user can use the application throw the remote control 
Connecting Arduino: This page will search for the Arduino and connect it with the 
application.

4.2 Code implementation:
◼ Connect Device Activity: 
package com.example.homeautomationarduino; 
import android.support.v7.app.ActionBar; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.MenuItem; 
public class ConnectDeviceActivity extends AppCompatActivity {

ActionBar toolbar; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.
activity_connect_device
); 
toolbar = getSupportActionBar(); 
toolbar.setTitle("Connect Your Arduino"); 
toolbar.setDisplayHomeAsUpEnabled(true); 
} 
@Override 
public boolean onOptionsItemSelected(MenuItem item) { 
int id = item.getItemId(); 
if (id == android.R.id.
home
) { 
this.finish(); 
} 
return super.onOptionsItemSelected(item); 
} 
} 
◼ Main Activity: 
package com.example.homeautomationarduino; 
import android.content.Intent; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.View; 
public class MainActivity extends AppCompatActivity { 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.
activity_main
); 
} 
public void openRemoteControlBTN(View view) 
{ 
Intent intent = new Intent(this, RemoteControlActivity.class); 
startActivity(intent); 
} 
public void openConnectionActivityBTN(View view) 
{ 
Intent intent = new Intent(this, ConnectDeviceActivity.class); 
startActivity(intent); 
} 
} 
◼ Remote Control Activity:

) { 
this.finish(); 
} 
return super.onOptionsItemSelected(item); 
} 
} 
4.3 Technology used:
We used some tools and software’s that help to build the system:
4.3.1 Android studio: 
it’s a software that use for creating the interfaces for the application that we have in the system by 
writing some codes and also its supported with connection to the database.
4.3.2 Arduino software: 
it’s a software that use for writing and uploading the code of how the board work to the Arduino 
board.
