Scope and global variable

Projects Programming

Hello everyone! I wrote this code and inside the for I get this error:
'servo' was not declared in this scope

#include <Servo.h>

int n_servo = 3;
Servo servo[n_servo];
void setup()
{
  for(int i = 0; i < n_servo; i += 1){
    servo[i].attach(11 + i);
  }
}

If I declare Servo inside the setup it works, but I would like to keep the global variable and use it in some functions.

Thank you so much! it works!
New problem:

#include <Servo.h>

const int n_servo = 3;
Servo servo[n_servo];

void moveTO(int n_sync, int idx[], int degree[]){
  //code.........
}

void setup()
{
  for(int i = 0; i < n_servo; i += 1){
    servo[i].attach(11 + i);
  }

  moveTo(3, {0, 1, 2}, {0, 0, 180});
}

in this line: moveTo(3, {0, 1, 2}, {0, 0, 180});
this error: 'moveTo' was not declared in this scope

iacoposk8:
this error: 'moveTo' was not declared in this scope

Case is relevant.

Check 'moveTO' vs 'moveTo' (capital O)

(11 + i);

Much better to use an array of pin numbers. Then you aren't restricted to using physically adjacent pins.
