this is a project which i planned to make unfortunately didn't work.Is it possible for anyone to help me in the coding and circuit connections.By the way the project is a robot which can be controlled through bluetooth.The motor shield which I have is the official version of arduino not clone
What exactly do you mean by "didn't work"?
You need to explain in detail what you have done and post the code you have tried.
If you were copying a plan you need to post a link to the plan details.

Sorry for the same Robin,
Here is the project site http://www.instructables.com/id/MultiTasking-Robot/?ALLSTEPS
The problem is that after uploading the code when I switch it on it fails to start the motor and I don't know why even after replacing all the batteries then also I don't understand why.I am using a official arduino and motor shield R3. If you cannot solve it you may try the following simple bluetooth robot
Here it is http://www.instructables.com/id/How-to-control-an-arduino-car-via-Bluetooth-for-be/?ALLSTEPS.
By the way all codes should be writen for 4 motors.
Please try your best as this is my exhibition project.
Would appreciate for the help

Post the connections you did and the code you uploaded.
Broadly there are two areas where the problem exists - either in your hardware (incorrect wiring, for example) or in the software.
To find an error in the software you will need to add debug statements into your code to get some idea of where it is failing.
To test the hardware it would be a good idea to try it with some very simple programs - for example just to make the motor go forward and backward for a few seconds each way.

The thing is that I am pretty new to this arduino so I don't know much about debug statements.
The connections I made are the same as that given in the website above one which is the multitasking robot.
A Motor requires more current than the arduino can handle, thats why ur using a motor driver. It basically takes commands from the arduino and "drives" motors accordingly.
You shouldnt be lazy when asking for help. If you dont know what debug statements are, search and read about it.
Post the exact code which you have used, its just copy paste work. If you cant do it, nobody will bother to search for it.
Also post the connections diagram, atleast send some clear pictures of it. Without proper connections, code is of no use.
