I am having a weird problem. I have an application on my Duemilanove that is very simple. It just turns a servo motor every 5 seconds, but instead it is turning the motor intermittently.
The problem is that it will not work unless I add "Serial.begin(9600)" at the top. The code is in this thread: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1283064513. The relevant posts are #1 and all the ones past #10.
