help .. for step by step what can i do ? [my final lecture]

hello my name jony , i'm from indonesian

I wanted to make the final lecture in my university using arduino + android
I have an idea that is a way of working which issued Arduino running text with dot matric or 7/8 segment where the posts are going to come out that is based on input from android. for its communication using bluetooth

does anyone here know how to move - his steps should I do?

I want to ask to the community in the country. Her website is down but was a few months. : :~

Hi Jony from Indonesia, welcome.

For the both of us, English isn't our native language.
Because of that, i'm having some difficulty reading or understanding your question.
I understand that you want to use an Android device and an Arduino with a LED display for your thesis.
And you want to use Bluetooth communication between these units.

I don't get what it is you like to send over Bluetooth, can you explain a bit more about that ?
Maybe by some example.
Also: Do you already have any components you want to use or do you have a wish list ?

If you haven't started yet, you should start with making a list of things you need (and / or want) to do for your doctorate paper.
For instance: How many characters does the display need to display at any given time, and are those alphanumerical or just numerical characters ?
