how to control stepper motor with gear reducer, i am very confused, please someone give me a code to control stepper motor with gear ratio 1:14 using arduino, thank you very much!!!

Which Arduino board are you using ?
How is the stepper powered ?
Have you got a sketch to move the stepper motor ?

What is your motor's part number? Which motor driver are you using?
What is your power supply's voltage and current ratings?

Look at any stepper project. The gearbox only divides the movement by 14 and multiplies the torque by 14 relative to the stepper alone.

I am using arduino uno,driver tb6600, power 12V 2Ahttps://cuahangvattu.com/products/dong-co-buoc-42-kem-hop-giam-toc-step-motor-42-robot

#define stepPin 2
#define dirPin 3
#define en 4

int microStep = 32; //đây là số điều chỉnh trên tb6600, cần sửa s1 s2 s3
float angleStep = 1.8;
float stepsPerRound = microStep * 360.0 / angleStep; //200 xung
long steps = 1 * stepsPerRound;
int speedV = 240; //rpm
float speeds = 1.0 / (speedV/60 * stepsPerRound)  / 2.0 * 1000000;
void setup() {
  Serial.begin(9600);
  // Declare pins as output:
  pinMode(stepPin, OUTPUT);
  pinMode(dirPin, OUTPUT);
  pinMode(en, OUTPUT);

  digitalWrite(en, LOW);
  delay(5000);
  Serial.println(speeds);
}
void loop() {

  delay(1000);

  // 2 round in clock
  digitalWrite(dirPin, HIGH);
  steps = 15 * stepsPerRound; //400
  Serial.print("Move to ");
  Serial.print(steps / stepsPerRound, 0);
  Serial.print(" rounds ");
  Serial.println(steps);
  for (long i = 1; i <= steps; i++) {
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(speeds);
    digitalWrite(stepPin, LOW);
    delayMicroseconds(speeds);
  }

  delay(1000);

  // 5 round in unclock
  digitalWrite(dirPin, LOW);
  steps = 15 * stepsPerRound;
  Serial.print("Move to ");
  Serial.print(steps / stepsPerRound, 0);
  Serial.print(" rounds ");
  Serial.println(steps);
  for (long i = 1; i <= steps; i++) {
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(speeds);
    digitalWrite(stepPin, LOW);
    delayMicroseconds(speeds);
  }
}

Control it the same way you control any stepper.

The gearbox just reduces the step size by a factor of 14, with added "backlash".

Look up backlash, if you don't know that term.

Thank you very much, I look forward to receiving your comments on my code.
