Tip: Before trying to connect using rosserial, check if the Arduino is still running: blinking leds or something. For formating: There's a button with zeros/ones in the top. |

Yes. You write your .ino file, with ros libraries included. As spmaniato has stated, follow the tutorials first to understand how it works: http://wiki.ros.org/rosserial_arduino... From 1 up to 4 should be enough. |
