I think no body can help you in this matter.....
reason
1. you never mentioned this project is for student or commercial level.
2. You did not mention the technology to be used.
3. did not even mentioned about controller and programming language used.
4. whatever project you do, has nothing new at all other than playing with port pins of controller.
5. If we tell you about some unkown project how will you do it.....
6. You never told your area of expertise to us to jugde if you can do the project with ideas or will repeatedly come back for help.............
