hi, i create a node arduino that publish a variable with 3 values in Int8 type, and also i create a node cpp that subscribe in the variable value. when i subscribe, i receive a value fix and different to my values with 8 numbers. what can i do please? this is my code:

    #include "ros/ros.h"
#include "std_msgs/Int8.h"
void angleCallback(const std_msgs::Int8& servo_msg)
ROS_INFO("I turn: [%i]", servo_msg);
int main(int argc, char **argv)
ros::init(argc, argv, "angle_listener");
ros::NodeHandle n;
ros::Subscriber sub = n.subscribe("/servo", 1000, angleCallback);
return 0;
