graduate project ideas  ?!?!?

Hello for all
Im in final year in the electrical/computer engineering department , and im searching for graduate project ideas ,sure im thinking in using arduino board for the project.
please help me
thanks.

Could you specify your subject more?

Control
Processing / Analytics
Robotics
Security

Something else?

What are your interests outside of school? The project will be more interesting and larger in scope (and therefore more impressive) if it's something you are passionate about.

ok
there is no specific subject , but am thinking in controling

Test instruments make fine EE projects.
Multi-channel voltmeter.
Oscilloscope.
Logic Analyzer.
Audio Spectrum Analyzer.
Signal Generator.
Serial Protocol Analyzer.
In each case, you can add complexity by varying the I/O. Simplest would be to work via the normal serial connection to a PC. Followed by buttons and a keypad and character LCD. Followed by a VGA monitor. Followed by a bare LCD screen. And keyboards and/or touchscreens...

I say, think of where you want to work. The pick a project that would be good to talk about during an interview with that company. Make sure it is something you can accomplish though.

If you really nail the project, you will have something to talk about, that really demonstrates your depth of understanding.
