Piezo Vibration sensor as blow sensor to run DC motor

The loop code needs an if else statement;

if ((sensorReading < threshold) && (sensorReading > sensorMin))
  {
    Serial.print("blowing ");
    Serial.println(sensorReading);
    digitalWrite (motorPin,HIGH);
  }
else
  {
    Serial.print("Not blowing ");
     Serial.println(sensorReading);
     digitalWrite (motorPin, LOW);
  }

That way the motor is on when the sensor is in range and off when its not. No delays
