using ros::shutdown() in arduino code

Hey there guys,

I am trying to write an arduino based code for my robot, that would allow me to use a button on the PS3 joystick as an emergency kill-switch. I thought using ros::shutdown() would work, but apparently the arduino ros library doesn't recognize it as a function. Here is the code.

#include <ArduinoHardware.h>
#include <ros.h>
#include <geometry_msgs/Twist.h>
#include <sensor_msgs/Joy.h>

ros::NodeHandle nh;

geometry_msgs::Twist msg;

void joyCall(const sensor_msgs::Joy& joy){
if (joy.buttons[14]==1)

ros::Subscriber<sensor_msgs::Joy> sub("bluetooth_teleop/joy", &joyCall);
ros::Publisher pub("/cmd_vel", &msg);

void setup()
void loop(){


Basically, I am publishing a constant velocity to the velocity node, but i want to kill the publisher as soon as a button on the joystick is pressed. However, I get this compiler error:

sketch_jun24a.ino: In function ‘void joyCall(const sensor_msgs::Joy&)’:
sketch_jun24a.ino:13:3: error: ‘shutdown’ is not a member of ‘ros’

Any help would be extremely useful. Thanks!
