Return 1 if the servo is currently attached.

If you observe carefully, you will notice that many values have different ranges in programming. For example, the range
of values for analog inputs is (0~1023). The value range for the analog output is (0~255). The output angle of the servo
is (0~180).
This means that if we want to use the potentiometer to control the brightness of the LED or the angle of the servo, we
need to go through a mapping operation.
Now let’s see how to achieve it.
