I am new to ROS and i have successfully got through the following rosserial_arduino tutorial to blink an led connected to arduino,

I used the three terminal command provided to blink or trigger the led,

roscore rosrun rosserial_python _port:=/dev/ttyUSB0 rostopic pub toggle_led std_msgs/Empty --once

But i want to write a program/application on my PC to trigger the program running on the arduino, I dont know how to do that, I need help. I also tried to right my own publishing program to the topic "toggle_led". But stucked at some where middle while creating and building a new ros package??
