...but it is not working
I assume you mean the electronics ? are not working. What exactly does it do or not do? It'll help if you post a clear picture of your components and the soldering job you did. Maybe someone here can spot a problem.
i also need help to explain this circuit to my college examiner
It's called homeWORK for a reason!

Try looking up H-bridge motor control, and using transistors to make a flip-flop.
