About this project

Overview

I decided to make this project because when I make any project with motors and use a motor driver, it consumes lot of energy and yields low performance. Due to this, sometimes projects won't work well. And so that is the reasoning behind this project.

Code

Motor DriverArduino
const int in1 = 9;
const int in2 = 8;
const int in3 = 4;
const int in4 = 3;

void setup() {
  pinMode (in1, OUTPUT);
  pinMode (in2, OUTPUT);
  pinMode (in3, OUTPUT);
  pinMode (in4, OUTPUT);

}

void loop() {
      //Move Farword 
      digitalWrite(in1, HIGH); 
      digitalWrite(in2, LOW); 
      digitalWrite(in3, HIGH); 
      digitalWrite(in4, LOW);
      delay(2000);

      //Move Reverse 
      digitalWrite(in1, LOW); 
      digitalWrite(in2, HIGH); 
      digitalWrite(in3, LOW); 
      digitalWrite(in4, HIGH);
      delay(2000);

      //Move Left 
      digitalWrite(in1, HIGH); 
      digitalWrite(in2, LOW); 
      digitalWrite(in3, LOW); 
      digitalWrite(in4, HIGH);
      delay(2000);

     //Move Right
      digitalWrite(in1, LOW); 
      digitalWrite(in2, HIGH); 
      digitalWrite(in3, HIGH); 
      digitalWrite(in4, LOW);
      delay(2000);
