Hi Burt,
It’s great you’re getting involved with ROS. However we ask that help and debugging questions be asked on http://answers.ros.org instead of here on discourse. The Q&A website is optimized to provide answers as efficiently as possible while this site we focus on announcements and discussions scoped appropriately for each category.
A quick search shows that there are already several questions with answers about servos and rosserial on arduinos.
For more informatoin please take a look at the guidelines for asking questions are at http://wiki.ros.org/Support The more complete you can ask your question the better answer you can get.
