Smart phone Android Operated Robot

The project aims in designing a Robot that can be operated using Android mobile
phone. The controlling of the Robot is done wirelessly through Android smart phone
using the Bluetooth feature present in it. Here in the project the Android smart phone is
used as a remote control for operating the Robot.
Android is a software stack for mobile devices that includes an operating system,
middleware and key applications. Android boasts a healthy array of connectivity options,
including Wi-Fi, Bluetooth, and wireless data over a cellular connection (for example,
GPRS, EDGE (Enhanced Data rates for GSM Evolution), and 3G). Android provides
access to a wide range of useful libraries and tools that can be used to build rich
applications. In addition, Android includes a full set of tools that have been built from the
ground up alongside the platform providing developers with high productivity and deep
insight into their applications.
Bluetooth is an open standard specification for a radio frequency (RF)-based,
short-range connectivity technology that promises to change the face of computing and
wireless communication. It is designed to be an inexpensive, wireless networking system
for all classes of portable devices, such as laptops, PDAs (personal digital assistants), and
mobile phones. It also will enable wireless connections for desktop computers, making
connections between monitors, printers, keyboards, and the CPU cable-free.
The controlling device of the whole system is a Microcontroller. Bluetooth
module, DC motors are interfaced to the Microcontroller. The data received by the
Bluetooth module from Android smart phone is fed as input to the controller. The
controller acts accordingly on the DC motors of the Robot. The robot in the project can
be made to move in all the four directions using the Android phone. The direction of the
robot is indicated using LED indicators of the Robot system. In achieving the task the
controller is loaded with a program written using Embedded ‘C’ language.

Electronics phone locker

Phone locker
Building a electronics phone lock is so easy. Any one can build it their home by the help of few electronics components. The phone locker is very simple to construct and can be housed in a small plastic cabinet of the size of a match box. Only you have to connect it in the phone as shown in the circuit diagram.
PART LIST
PARTS LIST Telephone     -
Resistor     220 K
LED     GREEN
LED     RED
Capacitor     1 400V
Switch     SP

Description
When the handset is removed from cradle of the telephone, one of the LEDs lights up, indicating that the phone is not dead. And on dialling required number, the LEDs start flickering, indicating that the number is being dialled. This way one can detect whether someone is misusing the phone from the wires going outside the house.

Once the ringing tone reaches the caller and the caller lifts his own handset, the other LED lights up indicating that the call is matured. For differentiation, two different coloured LEDs have been used. This happens due to reversal of the polarity of voltage in the exchange wires. When switch is moved to ‘off position, the capacitor is introduced in the circuit. In this position the phone becomes for the outgoing calls but the incoming calls regularly come through the capacitor, i.e. you can listen to the voice of the caller but they cannot listen to your voice. So, to enable the incoming calls, the switch should be moved to ‘on’ position and the conversation made as usual.

In this way you can build the electronics phone lock in your home.

Share images,music,video between PC and android phone .no usb cable

DO YOU HAT YOU CAN view your images,music and video present in your android phone in the PC or laptop when they are present in the same network with out copying it .It is needed when you have to see the video or images in the big screen of the computer.and you feel boring to use the usb cable for copying it to to the computer.than here is the solution for you just try it once for the enjoyment and post us the comment.

In this task we will show you how you can stream video, photo or music from your mobile phone directly on to a desktop PC or laptop. All you need is a simple free Android app called VLC Direct, a media playback application called VLC Media Player on your PC, and the two connected to the same network. Download VLC Direct for free from Google Play.You must have to install VLC media player in your pc. Connect the PC and the Android phone to a wireless router and you are ready to stream.

STEP 1:

Start VLC Direct on your Android phone. A small wizard will guide you through the process of configuring the video streaming necessities. Dont quit the application or press the back button on your phone, VLC Direct will exit and not show you the wizard again. In this case, you can press the Menu button, go to ‘Settings’, and select the ‘Automatic Connection Wizard’ to re-initiate the wizard.

STEP 2:

Start your PC, connect it to a large screen LCD TV if you want to enjoy videos on a big screen. Start VLC Media Player on your PC. Click on ‘View | Add interface | Web interface’ and leave VLC Media player as it is.

STEP 3:

On the mobile phone screen, select the ‘Start’ button and the VLC Direct app will start scanning for the machine with VLC Media Player on your local network. Once that is done, you will receive a toast message stating that it has found the player and the configurations have been set.

You are now ready to stream your media files onto your PC instantly. Using the Android handset, you can sit back and scroll through your list of videos, photos, or music files and watch play them back on the big screen. You can control the playback (stop, play, pause, forward or rewind) and the volume controls too. What’s more, you can also pull up the list of media files stored on the PC (running the VLC Media Player) and play those.

The VLC Direct interface includes playback control buttons, icons for video and music on your phone, a monitor icon for listing files available on the remote PC and the VLC icon for playlist. Towards the top-left of the screen, you will find an Android logo icon (target), which is a toggle button that can be used to direct the video stream to your PC from your handheld or from the PC to the handheld. The screenshots here will explain these buttons in detail.

Streaming media from the PC to the Android is pretty simple using the target button. Using this mood is beneficial as you don’t need to transcode or convert your video into compatible format for your Android device. You can also save on storage space on your phone by treating the PC as a media server. Streaming from your PC to the Android device can also be convenient when someone else is using the laptop and you’d like to assess media content on it.

[ SOLUTION ] ANDROID phone do not respond

The phone doesn't respond at all

Problem:

It may happen that your Android phone or Android tablet will not respond at all. This is what once happened to my HTC One X. I ended a call, the phone froze so I waited, waited, waited. The screen turned off and the phone behaved as if it was turned off (but I know it wasn't). In such a situation, we usually remove the battery. But what can we do if there is no battery to remove like in my HTC? :)

Solution:

When the phone is unresponsive, it's usually a good idea to restart it. You can do that by holding the power button for a few seconds and then tapping Restart phone. This solves the problem in most cases.
Android Problems

You can also remove the battery (if you have one), which always helps. In the case of my HTC, the only thing that worked was to hold the Power button for 10 seconds. After that the phone automatically restarted and everything went back to normal.
