Servo.attach()

Servo.attach(pin，min，max)

作用

舵机初始化，连接到引脚pin上,并设置控制角度的脉冲的高电平时间范围min-max，一般在0.5ms-2.5ms之间

参数

pin:引脚号

min:控制角度的脉冲的高电平时间最小值，数值单位为us，默认544

max:控制角度的脉冲的高电平时间最大值，数值单位为us，默认2400

返回值

返回值n为当前舵机是被连接的第n号舵机，uint8_t型数据

Servo.attach(pin)

作用

舵机初始化，连接到引脚pin上,并设置控制角度的脉冲的高电平时间为默认范围：544-2400

参数

pin:引脚号

返回值

返回值n为当前舵机是被连接的第n号舵机，uint8_t型数据

示例

#include <Servo.h>

Servo myservo;  // create servo object to control a servo
// a maximum of eight servo objects can be created

#define servoPin  D9

int pos = 0;    // variable to store the servo position

void setup()
{
  myservo.attach(servoPin);  // attaches the servo on pin 9 to the servo object
}

void loop()
{
  for (pos = 0; pos < 180; pos += 1) // goes from 0 degrees to 180 degrees
  { // in steps of 1 degree
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position
  }
  for (pos = 180; pos >= 1; pos -= 1) // goes from 180 degrees to 0 degrees
  {
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position
  }
