Code to control 1 DC motor using L298N Module with 2 push buttons -Example 1

Project Video
Project Details

This this video shows how to use L298N Module to control 2 DC Motor fully with Robojax Library. We are using 2 push buttons to STOP/START rotate motor in Clockwise CW, or Counter Clockwise CCW.Please watch video for instruction. Download library.

In this page you will codes to control 1 motor and 2 motors using L298N Motor Controller module
See Code to control 2 DC motors using L298N Module with 4 push button (2 for each motor) -Example 2

Project Code

 * Library Example for L298N Module to control with 2 push buttons
 * One Push button is used for CW/CCW  
 * and One push button is used to stop the motor
