int enA =7;
int enB = 8;
int in1 = 9;
int in2 = 10;
int in3 = 11;
int in4 = 12;
void setup()
{
pinMode(enA,OUTPUT);
pinMode(enB,OUTPUT);
pinMode(in1,OUTPUT);
pinMode(in2,OUTPUT);
pinMode(in3,OUTPUT);
pinMode(in4,OUTPUT);
}
void loop()
{
digitalWrite(in1,LOW);
digitalWrite(in2HIGH);
digitalWrite(in3,LOW);
digitalWrite(in4,HIGH);
for(int m_speed=250; m_speed<255;m_speed++)
{
analogWrite(enA,m_speed);
delay(1000);
}
digitalWrite(in1,HIGH);
digitalWrite(in2,LOW);
digitalWrite(in3,HIGH);
digitalWrite(in4,LOW);
for(int m_speed=250; m_speed<255;m_speed++)
{
analogWrite(enB,m_speed);
delay(1000);
}
}

for this coding the stepper motor will work continiously or not.
