Not recieving Serial output from my sketch

       myservo.write(90);
       servopos = 90;

       myservo.write(180);
       servopos = 180;

Sooner or later, you're going to screw up and only change one of these pairs of values. I can almost guarantee it.

       servopos = 90;
       myservo.write(servopos);

       servopos = 180;
       myservo.write(servopos);

No possibility of a screw up, and it's exactly the same number of lines of code, and makes no difference to the servo.
