Create an example ROS topic for communicating with an arduino

[CalebJ2]

This seems like a good way to start getting the hang of ROS.

Went through the rosserial arduino setup tutorial: http://wiki.ros.org/rosserial_arduino/Tutorials/Arduino%20IDE%20Setup And the basic publisher tutorial: http://wiki.ros.org/rosserial_arduino/Tutorials/Hello%20World Need to figure out why the ros_lib in the libraries folder isn't being recognized.

https://wiki.ros.org/rosserial_arduino/Tutorials/Servo%20Controller We got this tutorial running to set the speed of the motor. We had to use this command to get it to run though on a different terminal. rosrun rosserial_arduino serial_node.py _port:=/dev/ttyUSB0

The Arduino Serial Library cannot be used at the same time as the Arduino rosserial.

    while not rospy.is_shutdown():
        test_str = input("Let get this tested out: ")
        rospy.loginfo(test_str)
        pub.publish(test_str)
        rate.sleep()

    try:
        talker()
    except rospy.ROSInterruptException:
        pass
