hi, we're trying to take data from arduino to ros, and send some value corresponding to it, back to the arduino. on the arduino side, the publisher works well but on the ros side the publisher is not publishing the data. we've tried the publisher and subscriber individually using python on ros side, but working with both of them is creating a problem.

hi every one. i just finished the beginners tutorial and i'm doing rosserial_arduino tutorial. i saw some video of controlling the robot using teleop package in a network by another laptop which should also be in a network. i searched, but couldnot find a clue where to start off with. please guide me where to start off.

above link only shows a block diagram. where do i start off from to get a bright start?
