Please do not cross-post.

Please read #7 below:

http://forum.arduino.cc/index.php/topic,148850.0.html

int potpin0 = analogRead (A0); // connect to pin 0 controls servo1
int potpin1 = analogRead (A1); // connect to pin 1 controls servo2
int potpin2 = analogRead (A2); // connect to pin 2 controls servo3
int potpin3 = analogRead (A3); // connect to pin 3 controls servo4

It makes no sense to use pin in the name of a variable that holds a (useless) value read from an analog pin.

Those values are NOT pin numbers.

int val0; // attaches the servo on pin 4-7 to the servo object

Utter nonsense.

servo1.attach(9); // attaches the servo on pin 4-7 to the servo object

More nonsense.

When a comment does nothing more than state the obvious, it MUST do so correctly.
