The easiest and inexpensive way to control DC motors is to interface the L293D Motor Driver IC with the Arduino. It can control both the speed and the spinning direction of two DC motors. And as a bonus, it can also control a unipolar stepper motor like the 28BYJ-48 or a bipolar stepper motor like the NEMA 17.

Mar 16, 2022 · In this tutorial, I will give you all the necessary information about controlling the speed and direction of a DC motor with an L293D motor driver IC using an Arduino UNO board. I have included a wiring diagram and details of Arduino code to control the DC motor by sending characters from Serial Monitor of Arduino IDE with multiple examples.

Control a DC Motor Using Arduino With L293D: You need a few components in addition to an Arduino Uno board and a breadboard for this project. You first need a DC motor, with a nominal voltage close to 5V so it can be powered by the Arduino board alone.

In this tutorial, we will learn to control a DC motor’s speed and direction using the L293D motor driver IC. The L293D IC is a powerfully built motor driver IC. It is a dual-channel H bridge motor driver IC which can be easily used to drive two motors.

In this tutorial, you’ll learn how to do Arduino L293D Motor Driver IC Interfacing and use the L293D with Arduino to control the speed and direction of DC motors. And we’ll create a couple of Arduino DC Motor Control With L293D IC Projects using PWM for motor speed control.

Dec 26, 2017 · This example shows how to control a DC motor speed and direction of rotation using Arduino UNO and L293D motor driver chip. 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 one DC motor.

Dec 26, 2022 · Which is why in this tutorial we will be using the popular L293D motor driver IC to simple control the speed and direction of the motor.

Learn how to control the speed and direction of a DC motor on the Arduino with an L293D motor driver. Wiring diagrams and example code included.

Apr 28, 2024 · Here’s a step-by-step guide on how to connect the L293D to a DC motor and Arduino: Connect the Vcc1 pin (pin 16) of the L293D to the 5V pin of the Arduino. Connect the Vcc2 pin (pin 8) of the L293D to the positive terminal of the external power supply.

Mar 27, 2025 · This guide explored the fundamentals of DC motor control using the Arduino Uno and the L293D motor driver. You’ve learned about the components needed, how to set up Arduino Uno R3 environment, and how to write code for motor control.
