Hello guys,
I am looking for a large outdoor LED dot 5mm to interface it with arduino
It is for my project .. Its dimensions should be more than or equal to 64x32
I almost lost my hope to find one .. 
If there isn't any or there are similar ones, tell me your suggestions and what should I do..
I have got only one week to do it.. so help me please.
thanks in advance .. 
64x32 is a pretty large display.
You haven't stated any other requirements like colors, or budget.
Prices can vary dramatically.
Your biggest issue is time.
It will be nearly impossible to order any sort of products/parts with only a week of time.
Anything you need will have to overnighted immediately (which can be quite costly)
or sourced locally.

If you have local access to something that has addressable LEDs you can make one up.
Something using strips of these.
Thanks bperrybap & LarryD for your reply
and regarding the LED display, the resolution does not matter and quality does not matter but the size does matter
So, as long as it is controllable by arduino it is okay. Because all I care about now is the big LED display
I think I will just quit
How about 4 of these 16x32 displays for 64x32 total?
CrossRoads
thank you for your reply
It is accepted .. but how can I do it?
I do not have any idea about arduino hardware/software 
But I thought be doing it I will learn a lot..
so, I need all the possible help I can get
I mean..
I merely have a background about arduino ..
but how can I connect all the LED displays together ?
and what will be the code for that?
and by the way.. I want to connect the display with arduino uno hardware and also
a temperature sensor (say. TP100) with it to get the data and display it in the same time.
Start with 1 and the software at adafruit:
Of course, we wouldn't leave you with a datasheet and a "good luck!" We have a full wiring diagrams and working Arduino library code with examples from drawing pixels, lines, rectangles, circles and text. You'll get your color blasting within the hour! On an Arduino, you'll need 12 digital pins, and about 800 bytes of RAM to buffer the 12-bit color image.

Okay.. let us start .
I will need 4 Medium 16x32 RGB LED matrix panels , arduino uno, some wires (male & female) ..
What else??
A big power supply. USB from computer only supplies 500mA. 5V regulator on the Arduino can only supply 800mA and only if the Barrel jack voltage is 7.5V, otherwise it is more than likely to overheat.
You can daisy chain these boards together for a huge display too..
Check for a freetronics reseller near you ...
Okay..
Thanks guys .. 
I have found in ( ebay ) website while I was looking for an LED display a subject on how to control the LED display by Arduino hardware .. see here
Even the code is ready 
So,I think it has everything I needed .. but there is still one question ..
Is it okay if I buy a DC 5V power supply but with different ampere value?
Or .. which values of the voltage and ampere are the best ?
Yes, 5VDC supply with a higher current rating is fine.
The parts will only draw what they need.
I don't see a needed current rating, so I'd estimate needed amount like this:
64/8 x 32/8 = 8x4 8x8 matrices, or 32 matrices.
Assume each matrix will have one column of 8 LEDs on at one time, drawing 20mA each x 8 = 160mA total.
32 * 0.16 = 5.12A, so you'll need a pretty hefty supply.
Wow ..
Okay .. thanks man
what about the code for the time ?
hmmm.
You specifically said you only had "only 1 week to do it".
That week is gone and now you are looking ebay parts with long delivery times.
If you really do have more time,
there are several solutions that could be done using mail order or ebay parts that have existing libraries
and demo examples.
That matrix you linked to on ebay says 2-4 weeks for delivery.
So please tell us what your real requirements/needs are and
how much time do you really have?
What is it that you really need to be able to do and when does it really need to be up and working?
("need" being the key word vs "want")
Alternatively, you could buy a pre-built programmable led matrix sign.
It wouldn't be 64 x 32 but it could up and going very quickly and easily.

Well, the time is up for doing it XD
but I decided to keep going until I finish it
" You have to finish what you have already started " , I think that is how they actually say it
So, It is only for me now to learn more and gain more experience and it is also
for anyone who would face the same situation as I do now
I only need to to to display the time and temperature in the LED sign
There are lots of Time Libraries.
Translating to the 64x32 display is dependent on the hardware that drives the display.
Does it use a large array with 1 bit/LED? Something else?
