  if(Serial1.available() > 0) { 
    val = Serial1.read(); 
  } 
  analogWrite(0, val);  
}

Description   Returns a number between 0 and 255 for the next byte that's waiting in the buffer. Returns -1 if there is no byte, although this should be avoided by first checking available() to see if data is available.
