Несколько определений предупреждений во время компиляции

Question

При работе с Arduino (VSCode и PlatformIO) я получаю несколько предупреждений multiple definition of xxx во время компиляции, которые приводят к следующей ошибке:

collect2: error: ld returned 1 exit status
*** [.pio/build/nanoatmega328new/firmware.elf] Error 1

Поскольку class Motor, кажется, уже определено в Arduino.h, мне пришлось создать namespace motor, и мне интересно, является ли это источником проблемы.

Вот мои файлы c ++ / h:

main.cpp:

#include "Arduino.h"
#include "Motor.h"

using namespace motor;

const int pin1Left = 5;
const int pin2Left = 6;
const int pin1Right = 9;
const int pin2Right = 10;

Motor leftMotor(pin1Left, pin2Left);
Motor rightMotor(pin1Right, pin2Right);

void setup() {
}

void loop() {

    leftMotor.forward();
    rightMotor.forward();
    delay(500);
}

Motor.h:

#include "Enum.h"

namespace motor{

class Motor {

    public:

        Motor(int pin1, int pin2);
        void backward();
        void forward();
        void setSpeed(Speed spd);
        void reverse();

    private:

        Speed speed;
        Direction dir;
        int pin1;
        int pin2;

};
}

Motor.cpp:

#include "Arduino.h"
#include "Motor.h"
#include "Enum.h"

using namespace motor;

Motor::Motor(int pin1, int pin2){

    pin1 = pin1;
    pin2 = pin2;
    dir = Direction::FORWARD;
    speed = Speed::SLOW;
    pinMode(pin1, INPUT);
    pinMode(pin2, INPUT);

}

void Motor::backward(){

    dir = Direction::BACKWARD;
    analogWrite(pin1, static_cast<int>(speed));
    analogWrite(pin2, 0);

}

void Motor::forward(){
    dir = Direction::FORWARD;
    analogWrite(pin1, 0);
    analogWrite(pin2, static_cast<int>(speed));
}

void Motor::setSpeed(Speed spd){
    speed = spd;
    if (dir==Direction::BACKWARD){
        backward();
    } else{
        forward();
    }
}

void Motor::reverse(){
    if (dir==Direction::BACKWARD){
        forward();
    } else{
        backward();
    }
}

РЕДАКТИРОВАТЬ - После замены #include "Motor.cpp" на #include "Motor.h" я все равно получаю:
