The circuit consists of one 8051 microcontroller and its supporting circuitry related to oscillator and reset l298n motor driver module a dc motor and a few push buttons.
Pwm dc motor speed control.
1 shows the 5v pulses with 0 through 50 duty cycle.
Pulse width modulation pwm or duty cycle variation methods are commonly used in speed control of dc motors.
When it comes to controlling motor speed uniformly and efficiently a pwm based controller becomes the ideal option here we will learn more regarding a simple circuit to implement this operation.
Direct current is applied to the armature by means of a carbon brush or by means of electromagnetic induction.
Arduino has inbuilt functions in its library which makes the task easily.
The frequency of pwm signal remains same.
Pwm stands for pulse width modulation where we can change pulse width of the signal.
In short the duty cycle changes.

In this chapter speed control of a dc motor using pulse width modulation pwm technique is described.
Pwm based dc motor speed control using microcontroller circuit design.
Pwm dc motor control with ic 555.
We can easily generate pwm using arduino.
Generally a dc motor consists of either an electromagnet or a permanent magnet and a wounded coil known as the armature.
