Turning a stepper motor

Projects General Guidance
1

so my background,
just getting back into this stuff. i haven't been the greatest at it understanding it wise; but i am trying and really want to get good.

so i have found go to get my stepper motor to turn on and rotate.

now i'm trying to put a button in play that when it is pressed it starts the rotation of the stepper and the stepper rotate a certain number of times.

is there a code that exist that does this already for one stepper?
if not where is a good place for me to start to look to understand.

is there an Arduino project that i can do to help myself learn what this type of come is saying and how its applied?

thank you in advance for any patience and help.

Please post your code here as a starting point

If you need more assistance please post a link to the datasheet for your stepper motor and tell us what stepper motor driver you are using.

//Simple stepper motor control demo

const int stepPin = 3; //pin to pulse for steps
const int dirPin = 2; //pin to change step direction

void setup(){

//set pins as outputs
pinMode(stepPin, OUTPUT);
pinMode(dirPin, OUTPUT);
}



void loop(){

//step forward 100 steps
stepperFWD();
for(int i = 0; i < 100; i++){
motorStep();
delay(1);
}

//step backwards 100 steps
stepperREV();
for(int i = 0; i < 100; i++){
motorStep();
delay(1);
}

}

//change the stepper direction to forward
void stepperFWD(){
digitalWrite(dirPin, HIGH);
}

//change the stepper direction to reverse
void stepperREV(){
digitalWrite(dirPin, LOW);

}

//have the stepper motor take one step
void motorStep(){
digitalWrite(stepPin, HIGH);
delay(1);
digitalWrite(stepPin, LOW);
}

this is just a code that i have that i took from someone else as a starting point. i will be taking reverse out so that isnt an issue. so this is where im at for trying to understand what is being said. oh yeah how do i attach code so it isnt so big on the screen

Either You go to a toyshop one lucky day and find the entire proj ready, or You create it Yourself.

Something to start with, what about this:

void loop(){

  if( !start_button( start_button_pin){

    //step forward 100 steps
    stepperFWD();
    for(int i = 0; i < 100; i++){
    motorStep();
    delay(1);
  }
}

Define start_button in Setup as INPUT_PULLUP. Connect the button to GND and button input-
