combining different code into one

Using Arduino Project Guidance
1

Hi, so i'm pretty new at coding and so i wanted to work with a stepper motor.
I got a stepper motor to turn one direction and to turn in reverse.
however, i can only execute them separately and what i want to accomplish is to have the motor spin one direction for 10 seconds, stop for 2 seconds and spin the other direction for 10 seconds.
How can i go about doing that?

the code for spinning one direction is

int delaylegnth = 10;

void setup(){
//establish motor direction toggle pins
pinMode(12, OUTPUT); //CH A -- HIGH = forwards and LOW = backwards
pinMode(13, OUTPUT); //CH B -- HIGH = forwards and LOW = backwards
//establish motor brake pins
pinMode(9, OUTPUT); //brake (disable) CH A
pinMode(8, OUTPUT); //brake (disable) CH B
}

void loop(){

// THIS IS FOR WHEN THE ROBOT IS MOVING FORWARD TOWARDS THE MIDDLE OF THE ROAD

digitalWrite(9, LOW); //ENABLE CH A
digitalWrite(8, HIGH); //DISABLE CH B
digitalWrite(12, HIGH); //Sets direction of CH A
analogWrite(3, 255); //Moves CH A
delay(delaylegnth);

digitalWrite(9, HIGH); //DISABLE CH A
digitalWrite(8, LOW); //ENABLE CH B
digitalWrite(13, LOW); //Sets direction of CH B
analogWrite(11, 255); //Moves CH B
delay(delaylegnth);

digitalWrite(9, LOW); //ENABLE CH A
digitalWrite(8, HIGH); //DISABLE CH B
digitalWrite(12, LOW); //Sets direction of CH A
analogWrite(3, 255); //Moves CH A
delay(delaylegnth);

digitalWrite(9, HIGH); //DISABLE CH A
digitalWrite(8, LOW); //ENABLE CH B
digitalWrite(13, HIGH); //Sets direction of CH B
analogWrite(11, 255); //Moves CH B
delay(delaylegnth);

}

and to go the other direction, the code is

int delaylegnth = 10;

void setup() {

//establish motor direction toggle pins
pinMode(12, OUTPUT); //CH A -- HIGH = forwards and LOW = backwards???
pinMode(13, OUTPUT); //CH B -- HIGH = forwards and LOW = backwards???
//establish motor brake pins
pinMode(9, OUTPUT); //brake (disable) CH A
pinMode(8, OUTPUT); //brake (disable) CH B

}

void loop(){

digitalWrite(9, LOW); //ENABLE CH A
digitalWrite(8, HIGH); //DISABLE CH B
digitalWrite(12, HIGH); //Sets direction of CH A
analogWrite(3, 255); //Moves CH A

delay(delaylegnth);

digitalWrite(9, HIGH); //DISABLE CH A
digitalWrite(8, LOW); //ENABLE CH B
digitalWrite(13, HIGH); //Sets direction of CH B
analogWrite(11, 255); //Moves CH B

delay(delaylegnth);

digitalWrite(9, LOW); //ENABLE CH A
digitalWrite(8, HIGH); //DISABLE CH B

digitalWrite(12, LOW); //Sets direction of CH A
analogWrite(3, 255); //Moves CH A

delay(delaylegnth);

digitalWrite(9, HIGH); //DISABLE CH A
digitalWrite(8, LOW); //ENABLE CH B
digitalWrite(13, LOW); //Sets direction of CH B
analogWrite(11, 255); //Moves CH B

delay(delaylegnth);

}

Can anyone help me out?

Make each of your loop() routines into subroutines, like this:

void forward() {

  digitalWrite(9, LOW);  //ENABLE CH A
  digitalWrite(8, HIGH); //DISABLE CH B
  digitalWrite(12, HIGH);   //Sets direction of CH A
  analogWrite(3, 255);   //Moves CH A
  delay(delaylegnth);

  digitalWrite(9, HIGH);  //DISABLE CH A
  digitalWrite(8, LOW); //ENABLE CH B
  digitalWrite(13, LOW);   //Sets direction of CH B
  analogWrite(11, 255);   //Moves CH B
  delay(delaylegnth);
  
  digitalWrite(9, LOW);  //ENABLE CH A
  digitalWrite(8, HIGH); //DISABLE CH B
  digitalWrite(12, LOW);   //Sets direction of CH A
  analogWrite(3, 255);   //Moves CH A
  delay(delaylegnth);
    
  digitalWrite(9, HIGH);  //DISABLE CH A
  digitalWrite(8, LOW); //ENABLE CH B
  digitalWrite(13, HIGH);   //Sets direction of CH B
  analogWrite(11, 255);   //Moves CH B 
  delay(delaylegnth);

}

void backward () {

  digitalWrite(9, LOW);  //ENABLE CH A
  digitalWrite(8, HIGH); //DISABLE CH B
  digitalWrite(12, HIGH);   //Sets direction of CH A
  analogWrite(3, 255);   //Moves CH A
  
  delay(delaylegnth);
  
  digitalWrite(9, HIGH);  //DISABLE CH A
  digitalWrite(8, LOW); //ENABLE CH B
  digitalWrite(13, HIGH);   //Sets direction of CH B
  analogWrite(11, 255);   //Moves CH B
  
  delay(delaylegnth);
  
  digitalWrite(9, LOW);  //ENABLE CH A
  digitalWrite(8, HIGH); //DISABLE CH B

  digitalWrite(12, LOW);   //Sets direction of CH A
  analogWrite(3, 255);   //Moves CH A
  
  delay(delaylegnth);
    
  digitalWrite(9, HIGH);  //DISABLE CH A
  digitalWrite(8, LOW); //ENABLE CH B
  digitalWrite(13, LOW);   //Sets direction of CH B
  analogWrite(11, 255);   //Moves CH B
  
  delay(delaylegnth);

}

then put them both in loop(), using if-else:

void loop () {

if ( theDirection == 0 ){
 forward();
} else {
 backward();
}

Of course you will need your program also to set the value of the variable called theDirection. Maybe with a button, or count the steps.

Post a link to the datasheet for your stepper motor.

You seem to be using a h-bridge to control the motor. If you have a bipolar motor a specialized stepper motor makes the programming much easier because it just need step pulses on one pin and a direction signal on another.
