The L293D quadruple half-H drivers chip allows us to drive 2 motors in both directions, with two PWM outputs from the Arduino we can easily control the speed as well as the direction of rotation of ...

A critical function of motor operation is speed control, which allows us to adjust the motor speed as per the application’s requirements. This guide explains the construction and operation of a DC ...

Abstract This paper describes the development and implementation of a control system for a direct current (DC) motor using the Arduino Uno microcontroller, based on the speed and direction control of ...

A DC motor is normally operated by direct current. It converts the electrical energy into mechanical energy. This rotational movement is the source of required power to run many applications in ...

This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few ...
