adding void attach(void) to Servo.h

[BastelBaus]

What about adding a attach function to the Servo.h w/o giving a pin. This could be used to attach the Sero within the code without giving the pin name once it was initialized (e.g. in setup)

Arduino/libraries/Servo/src/Servo.h

Line 73 in 78d0d0a

uint8_t attach(int pin);

uint8_t Servo::attach(void) {
    if (_pin != 0) {
        pinMode(pin, OUTPUT);
        digitalWrite(pin, LOW);
        _attached = true;
        write(_valueUs);
    }
    return _pin;
}
