I'm using ros kinetic on ubuntu 16.04. I'm able to perform the hello world code from rosserial tutorials http://wiki.ros.org/rosserial_arduino... However not being able to operate the servo example. Any ideas? no error on Arduino IDE. After i perform the test on the terminal roscore rostopic pub servo std_msgs/UInt16 8

the terminal output:publishing and latching message. Press ctrl-C to terminate Nothing after that
