Pwm dc motor controller is the circuit whose heart is astable oscillator ,that uses pwm technic to control the high ,medium and low speed of dc motor.
High ,medium and low speed can be obtain by varying the potentiometer manually.by doing so the dc motor is supplied by different duty cycles.
Also the dc motor direction can be controlled by changing the polarity of the power supplied to the dc motor
