Hi, everyone I have interfaced A3967 IC with Arduino to operate the stepper motor but the problem is that my motor is not rotating but only vibrating please suggest me that what could be the possible reasons the motor is not rotating and I have used A3967 Easy Driver circuit for this please look the schematics in the datasheet and also the code for this as I have attached below thank you.

 

Without taking a deep dive I would say you are trying to run the motor at too high a speed. You must ramp the velocity up from a slow speed to the running speed and similarly you must ramp the velocity down to stop.

 

When posting code things go better if you post your code using code tags so it looks like this:

/*
  EasyDriver-Stepper-Motor-Driver Module

*/

#define stp 2
#define dir 3
#define MS1 4
#define MS2 5

int x;

void setup() {
  pinMode(stp, OUTPUT);
  pinMode(dir, OUTPUT);
  pinMode(MS1, OUTPUT);
  pinMode(MS2, OUTPUT);

  digitalWrite(MS1, LOW);
  digitalWrite(MS2, LOW);
}

void loop() {
  digitalWrite(dir, HIGH);
  for (x = 0; x < 1000; x++)
  {
    digitalWrite(stp, HIGH);
    delay(10);
    digitalWrite(stp, LOW);
    delay(10);
  }
  delay(1000);

  digitalWrite(dir, LOW);
  for (x = 0; x < 1000; x++)
  {
    digitalWrite(stp, HIGH);
    delay(10);
    digitalWrite(stp, LOW);
    delay(10);
  }
  delay(1000);
}

I also agree with ...
