DC motors are commonly used in embedded system applications. Sharing here a DC MOTOR SPEED CONTROL circuit which is bacially a 555 Timer IC based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage.
This DC motor control circuit explains in detail to control the speed and direction of a DC motor by using 555 timer IC.
