Question about L298N on a Arduino powered Bigtrak

HI,

I'm in the middle of my first project , This is my setup

1. Bigtrak Jr (PCB removed , using 2 motors ,2 encorders and the chasis)

2. Arduino Uno R3

3. Dual H Bridge DC Stepper Motor Drive Controller Board Module L298N for arduino

 

I  need to turn the vehicle by rotating wheels on opposite directions . I modified the blink code , and surprisingly  works!

But I'm not sure if I'm doing this right because it was simple than I thought. Can someone with better knowledge confirm this please?

 

/*

  Blink

  Turns on an LED on for one second, then off for one second, repeatedly.

  This example code is in the public domain.

 */

// Pin 13 has an LED connected on most Arduino boards.

// give it a name:

int led = 13;

int led2 = 10;

// the setup routine runs once when you press reset:

void setup() {                

  // initialize the digital pin as an output.

  pinMode(led, OUTPUT);     

pinMode(led2, OUTPUT);     

 

}

 

// the loop routine runs over and over again forever:

void loop() {

  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)

  digitalWrite(led2, HIGH);   // turn the LED on (HIGH is the voltage level)

  delay(2000);               // wait for a second

  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW

  digitalWrite(led2, LOW);

  delay(1000);               // wait for a second

}

Thanks,I’m trying to figure

Thanks,

I’m trying to figure out if this is this the right way to aproach this , Obviously it works . For example below code rotates the robot 2 seconds one way and then turn it the other way for 2 seconds.

 

I can see what’s the logic is here

In1 ,In2 belongs to one motor and In3,In4 belonds to the other.

In1=HIGH will turn that wheel clockwise , In2 =HIGH will turn it anti clockwise

 

I did lot of googling but all most all the searches with L298 chip gives me results with a different board .In those examples you have to supply ‘A enable’ ,‘B enable’ from arduino as well . On this board there are two jumpers on those pins . 

 

int led1 = 10;

int led2 = 11;

int led3 = 12;

int led4 = 13;

 

// the setup routine runs once when you press reset:

void setup() {                

  // initialize the digital pin as an output.

pinMode(led1, OUTPUT);     

pinMode(led2, OUTPUT);     

pinMode(led3, OUTPUT);     

pinMode(led4, OUTPUT);     

 

}

 

// the loop routine runs over and over again forever:

void loop() {

  digitalWrite(led1, HIGH);   

  digitalWrite(led3, HIGH);   

  delay(1000);               

 

  digitalWrite(led1, LOW);    

  digitalWrite(led3, LOW);

  delay(1000);               

 

  digitalWrite(led2, HIGH);   

  digitalWrite(led4, HIGH);   

  delay(1000);               

 

  digitalWrite(led2, LOW);    

  digitalWrite(led4, LOW);

  delay(1000);               

 

}

 

 

 

Thank you
