Can I read PWM-Based DC Motor Speed Control on EtoBox?

PWM-Based DC Motor Speed Control by Pooja Ban is a document available to read on EtoBox.

What is PWM-Based DC Motor Speed Control about?

This document discusses using pulse-width modulation (PWM) technique to control the speed of a DC motor. PWM works by rapidly switching voltage to the motor on and off. The average voltage delivered is controlled by varying the on-time as a percentage of the total cycle time, known as duty cycle. A microcontroller can generate a PWM signal to control duty cycle and thereby regulate motor speed. The document proposes using an L293D motor driver and optocoupler to isolate the microcontroller from the motor, a
