Learn how to build a Arduino Opta DC motor controller with a pushbutton switch and a programmable human machine interface (HMI).

This article is for those who are interested in learning about the fundamentals of DC motor control in electronic systems. The most prevalent form of the motor is a direct current (DC). There is ...

In this article, we are going to control the speed and direction of dc motor using L293D IC and Arduino.

The circuit interfaces the PWM signal generated from the Arduino Uno to the 12V DC motor that is being driven. Forward-reverse switch S2 is used for changing the direction of rotation of the motor.
