Help with implementation of T-DS-OLED-MOD

Hello, I am a student currently doing a project that requires Arduino coding. I am not proficient at all. I am trying to include the code to show the value of the potentiometer that is used for speed control of my NEMA 17 stepper motor.

Below I have attached the working code for the speed control of the stepper motor with a potentiometer. Please advise me.

const int stepPin = 3;

const int dirPin = 2; 

int customDelay,customDelayMapped; // Defines variables

void setup() {

  // Sets the two pins as Outputs

  pinMode(stepPin,OUTPUT);

  pinMode(dirPin,OUTPUT);

  digitalWrite(dirPin,HIGH); //Enables the motor to move in a particular direction

}

void loop() {

  

  customDelayMapped = speedUp(); // Gets custom delay values from the custom speedUp function

  // Makes pules with custom delay, depending on the Potentiometer, from which the speed of the motor depends

  digitalWrite(stepPin, HIGH);

  delayMicroseconds(customDelayMapped);

  digitalWrite(stepPin, LOW);

  delayMicroseconds(customDelayMapped);

}

// Function for reading the Potentiometer

int speedUp() {

  int customDelay = analogRead(A0); // Reads the potentiometer

  int newCustom = map(customDelay, 1023, 0, 0,10000); // Convrests the read values of the potentiometer from 0 to 1023 into desireded delay values (300 to 4000)

  return newCustom;  

}

Did you have a question?
