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
}
}
