Control VLC Player using Android (Wifi Connected)

    My first application of Android comes here.In my first tutorial on Controlling VLC using JAVA you can see that the VLC provides a Web interface from which it can be controlled and it also accepts certain commands.So that can be used to control the media player in Local Area Network using any programming language.This time its Android Code: MainActivity.Java package com.example.first_app;import java.net.Authenticator;import java.net.URL;import android.os.Build;import android.os.Bundle;import android.os.StrictMode;import android.annotation.SuppressLint;import android.annotation.TargetApi;import android.app.Activity;import android.content.Intent;import android.graphics.Color;import android.view.Menu;import android.view.View;import android.widget.Button;import android.widget.SeekBar;import android.widget.SeekBar.OnSeekBarChangeListener;import android.widget.TextView;public class MainActivity extends Activity { @TargetApi(Build.VERSION_CODES.GINGERBREAD) @SuppressLint(“NewApi”) @Override protected void onCreate(Bundle…

4 Channel relay board using L293D

         Many time it requires controlling relays to automate different things in projects.But thing is generally Relays are driven by either high voltage and requires high current but most of the embedded systems works at lower voltage and the constrain is they cant provide high current.           Their comes the requirement of a circuit which can drive relays taking input from the micro-controller board and also provide the required current to drive relays.Transistors can be used as H-Bridge driver but it makes little…
