Help me to identify material for my project

[freebird1401]

I am working in building a system (Graduation Project) by using ardiuno (Prototype only) which does the following features:

1- cars pass the entrance of for example company.
2- When the system identifies it it will open the door to allow it to pass.
3- There is a display (LED or computer display) to welcome him by name and guides him to specific parking numbers.
4- It will also display how many parking lots available.
5- In the parking we need put another kind of sensor to update the system in case of someone not taking the suggested parking.
6- It will send an SMS to the employee who did not arrive yet notify them how many parking lots available.
7- All the information is connected to computer that can provide us with statistics (what time the employee arrived, what time he left,
etc… )
8- It will send the information to specific email.
This system will apply as prototype not in the actual parking.

I need your help in give me with advice of what equipments I need for this project what type of Arduino to buy?

How many one do I need to buy?

What to consider when try to program?

Can we use LED display for thisproject?

Another thing that we have how to extinguish between person passing the gate and car for the Arduino to count?

Which one is better to use Bluetoothor Ultrasonic if we want accurate counting?

and how to do it
Your Help is Highly Appreciated

and how to do it

So, you want us to do your graduation project for you?

For starters, you are doing this backwards. Start by deriving detailed system requirements from the 8 bullet points you posted. The more detailed the better. Think about what operations are implied by each requirement. Also think about what can go wrong with each operation, and what you will have to do to handle those problems. Design your system.

THEN start thinking about what hardware will solve your problems. How do you know an arduino will even work for you if you don't yet know what you are going to ask it to do?

Don't just ask somebody to tell you what to do. They won't know unless they do the same kind of system design that you're supposed to be doing. Do some research into what technologies will best address the problems. There are lots of technologies out there.

And keep us posted on your progress!

That's a pretty ambitious project, and honestly the specs you've given don't provide enough information to guide you to specific hardware.

First, you need a specific way to identify a car.. an RFID tag, photo recognition of the license plate, etc. You'll need one of those at the entrance, and one at each parking space so your system can learn what car has parked where. The hardware you need depends on the identification method you use. If the identifier is something the user carries, you'll need sensors to track the identifier and sensors to tell you which parking spaces contain cars whose users have left (and thus don't have an identifier in them).

As far as displaying a user's name and parking assignment goes, you can use any kind of hardware you want.. LCD screens, LED matrices, regular video screens, etc.

You probably need to do some more research and nail down the specific kinds of sensors you want.

the problem is Arduinos are hard to be found in my country so I am going to order it for Amazon this why I need to know what to buy and how many?

[adafruit_support_rick]

Refer to the two earlier posts. You need to know what you're doing before you order anything.
When is your project due?

[freebird1401]

I have already identify what I need to do in my first post.

The project is due on Oct, 2012

anyway think for help me with valuable information
I will buy everything
