could you send more details about the error message you receive from the Arduino IDE ?

it doesnt show any error.. but the servo doesnt move even after following the commands to b used after uploading the code

ah, so you can actually upload the code on your Arduino board? You said you were unable to do it. In the "Testing" section I guess one part is missing: after starting roscore, type in a new terminal the command
rosrun rosserial_python serial_node.py /dev/ttyUSBX(Make sure to use the correct USB)Asked by Femer on 2016-05-25 07:10:59 UTC
i already tried it. still it not moving.i connected an led to check whether there's any problem with the board,but that it isn't the problem. the servo progrm uploaded and rosrun n rostopic pub.. was also done even then its not happening..the ros core was also run

i was trying to give a HIGH to the powr socket through the code instead of directly connecting it to the vcc.
