well i am studying diploma in electronics engineering<<--What course is this, some 1-2 year associates degree or something. I would have to say this is not even close to Engineering, sorry to say.
I too am called an Engineer, but in the computer industry it seems they use that term widely. I am Not and engineer, my Mother and Father would be upset to see the term engineer used so loosely, and members here as well, sorry to say.
A good start would be a google search on circuits, ir or bluetooth. It seems your trying to circumvent the learning part, you need to read as much as you can about everything you can find
I believe the project you are trying is out of your scope at this point. Not to say you will not understand this as you learn the arts
I doubt anybody here is going to design your project for you, "help" is the key word here. Good luck on your journey.
Can you read schematics?
Best regards,
