"what is series resestor?"
Oh dear!
This is basic electronics. You need to put the software aside for a while, and learn about basic electronics. Or stick to a purely software-only project.

Clearly, the lecturer assumed that you understood these things.
As Erik observed earlier, either this 'lecturer' is asking you to do things he has not covered (which is unreasonable), or you have not been applying yourself to your course...
