A simple way to control the speed of a DC motor is to regulate the supply voltage with pulse width modulation (PWM).

Step 5: Make Iterations. Your motor will probably not work the first time, so you will have to constantly fiddle with the armature and the paper clips to make them line up and spin correctly. Problems that might make your motor not work are: The ends of the armature are not straight so it gets caught on the paper clips.
