Description

In this video I have designed a PWM motor speed controller for DC motors. The circuit is based on NE555 timer IC. The IC is used in Astable Multivibrator configuration to generate a PWM signal whose duty cycle will be controlled by a potentiometer. Moreover, this video also demonstrate the concept of a freewheeling diode and how to use it.
