Motor Control
Wiring diagram for the motor control circuit
Understand how to use pulse width modulation to control the speed of a DC motor. Students attach a paper fan to the shaft of the motor and use a Virtual Instrument to output a pulse train. By adjusting the duty cycle of the pulses in the train students can control the speed at which the fan spins.
