I want to make a gain controlled motor

[qoo]

I have chosen that project for my college. I will use a potentiometer
to vary the resistance and that resistance will vary the gain for the
motor, hence, we will change the speed of the motor by using a
potentiometer.
I think I will use LM741 for amplification. Plz... I want your
comments on that. Thanks

I'd call it a 'speed control' rather than a gain control. And it seems
to be a trivial and obvious application of off the shelf technology.
Arent you supposed to try and create something new and innovative and
usefull?
