Issues with RGB led and Servomotors - c++

Question

I'm on my first Arduino project... On this project, I use an RGB led and 2 Servomotors...
First off all, following OOP, I create a class to control my RGB led...
class StatusLED {
private:
int pinRed;
int pinGreen;
int pinBlue;
public:
StatusLED(int pinRed, int pinGreen, int pinBlue);
void RGB(int redValue, int greenValue, int blueValue);
};
It's working very well, without issues...
After there is all fine with the RGB led, I start to include my Servomotor code...
#include <Servo.h>
#define PIN_RGBLED_R 9
#define PIN_RGBLED_G 10
#define PIN_RGBLED_B 11
#define PIN_SERVO_H 12
#define PIN_SERVO_V 13
Servo servoH;
Servo servoV;
LED led(PIN_RGBLED_R, PIN_RGBLED_G, PIN_RGBLED_B);
void setup() {
servoH.attach(PIN_SERVO_H);
servoV.attach(PIN_SERVO_V);
}
And after I include the servo.attach() lines, my RBG led has a strange behavior, the colors that I used before, like Light Purple RGB(2, 0, 2);, doesn't work anymore, now when i try it, the led turns on with Red color.
If I comment the servo.attach() lines, the led works well.
Already tried:
Change Servo libraries version;
Change servos to another pins;
Someone can please help me?
EDIT:
Just to eliminate the doubt of my LED class are the problem, I create a new file...
#include <Servo.h>
#define PIN_SERVO_H 3
#define PIN_SERVO_V 4
#define PIN_RGBLED_R 9
#define PIN_RGBLED_G 10
#define PIN_RGBLED_B 11
Servo servoH;
Servo servoV;
void setup() {
pinMode(PIN_RGBLED_R, OUTPUT);
pinMode(PIN_RGBLED_G, OUTPUT);
pinMode(PIN_RGBLED_B, OUTPUT);
servoH.attach(PIN_SERVO_H);
servoV.attach(PIN_SERVO_V);
}
void loop() {
RGB(2,0,2);
delay(100);
RGB(4,0,4);
delay(100);
RGB(8,0,8);
delay(100);
RGB(16,0,16);
delay(100);
RGB(0,0,0);
delay(1000);
}
void RGB(int redValue, int greenValue, int blueValue) {
if (redValue > 255) {
redValue = 255;
}
if (greenValue > 255) {
greenValue = 255;
}
if (blueValue > 255) {
blueValue = 255;
}
if (redValue < 0) {
redValue = 0;
}
if (greenValue < 0) {
greenValue = 0;
}
if (blueValue < 0) {
blueValue = 0;
}
// This is a common anode RGB Led.
// So 255 is OFF and 0 is Fully ON
analogWrite(PIN_RGBLED_R, 255 - redValue);
analogWrite(PIN_RGBLED_G, 255 - greenValue);
analogWrite(PIN_RGBLED_B, 255 - blueValue);
}
And the problem continues... if I comment the lines of attach() the led works fine, without comment, it only blinks in Red color...

Depending on the version of your arduino, servo.attach only works on Pin 9 and Pin 10, which conflicts with your RGB pins. See https://www.arduino.cc/en/Reference/ServoAttach
