Have anybody expierienced servo jitter using NewSoftSerial?
When a byte comes in servo jerks a bit ...
NSS pins = NewSoftSerial wrtserial(2, 4);
Servo on = const int servoPin = 9;
Normal servo lib = #include <Servo.h>
Here's an idea - look up at the top-right of the forum - see that search box? Type in "servo jitter" and press return. I guarantee that you will find information on this very problem. Here's another: Do the same on the old forum:http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl
This is an issue that has been experienced by a lot of people in the past; I can't tell you if there is a real solution - but doing a bit of research before you ask about it may help.
