Evo kod ,pokusavam al dzaba ...

int stp = 5;  //connect pin 11 to step
int dir = 2;  // connect pin 10 to dir
int buttonPin = 11;     
int a = 0;

void setup()
{
 
  pinMode(buttonPin, INPUT_PULLUP);

  pinMode(stp, OUTPUT);
  pinMode(dir, OUTPUT);

}
void loop()
{

  if(digitalRead(buttonPin) == LOW) //functions based off of button pulling input pin LOW 

{
 
   
  
   
 if (a <  200)  //sweep 200 step in dir 1
   {
    a++;
    digitalWrite(stp, HIGH);   
    delay(10);               
    digitalWrite(stp, LOW);  
    delay(10);              
  
}
}
}
