Sample Code

int INA = 9;  
int INB = 10;
void setup() 
{ 
pinMode(INA,OUTPUT); 
pinMode(INB,OUTPUT); 
} 
void loop() 
{ 
analogWrite(INA, 255);
digitalWrite(INB,LOW); 
delay(5000);
digitalWrite(INA,LOW);
digitalWrite(INB,LOW); 
delay(200); 
digitalWrite(INA,LOW);
analogWrite(INB, 255);
delay(5000); 
digitalWrite(INA,LOW);
digitalWrite(INB,LOW); 
delay(200); 
}


Test Result

The fan will rotate clockwise for 5S at Max speed, stop for 0.2S; then rotate counter-clockwise for 5S at Max speed, stop for 0.2S; then repeat the cycle.
