Arduino - Servo.attach()
Descripción
Conecte la variable Servo a un pin. Tenga en cuenta que en Arduino 0016 y anteriores, la biblioteca de servo sólo es compatible con los servos en sólo dos pines: 9 y 10.
Sintaxis
servo.attach(pin)
servo.attach(pin, min, max)
Parámetros
- servo: una variable de tipo Servo
- pin: el número del pin que el servo está conectado
- min (opcional): el ancho de pulso, en microsegundos, correspondiente al ángulo mínimo (0 grados) del servo (por defecto 544)
- max (opcional): el ancho de pulso, en microsegundos, correspondiente al ángulo máximo (180 grados) del servo (por defecto 2400)

#include <Servo.h>
Servo myservo;
void setup()
{
myservo.attach(9);
}
void loop() {}
※ Nota:
When calling Servo.attach() function, the servomotor rotates to the last value set by Servo.write() or Servo.writeMicroseconds() function, or 90 ° by default. Therefore, To position the servomotors at a certain position upon initialization, use Servo.write() or Servo.writeMicroseconds() function right before calling Servo.attach().
