How to operate a DC motor using Arduino

A direct current motor (DC motor) is a very basic type of motor. DC motor has amazing features like higher starting torque, variable speeds based on provided input voltage, rapid starting and stopping, and cheaper controlling than AC motors.

The speed of the DC motor can be changed by varying the applied input voltage. If the applied voltage is high then the motor rotates at a higher speed similarly if the applied voltage is low that means the motor will rotate at a lower speed.

I have used 5 volt DC motor, for which applying a 5-volt input voltage to the DC motor will provide a higher speed while applying the lower voltage will provide a lower speed.DC motor normally has two leads one is positive and the other one is negative. If these two leads are directly connected to the battery, the motor will rotate in a particular direction. If we exchange the leads, the motor will rotate in the opposite direction.

In this article, you will learn how a DC motor can be operated using Arduino Uno. DC motor should not be operated directly by the Arduino Uno pins. It will damage the board, to avoid this situation I will use the transistor as a switch to operate the motor using Arduino. I am providing a very basic circuit connection example that will help you to understand how a DC motor can be turned on and off with the help of a transistor.
