舵机操作+源代码

1.servo类成员函数

函数	说明
attach()	设定舵机的接口，只有9或10接口可利用。
write()	用于设定舵机旋转角度的语句，可设定的角度范围是0°到180°。
writeMicroseconds()	用于设定舵机旋转角度的语句，直接用微秒作为参数。
read()	用于读取舵机角度的语句，可理解为读取最后一条write()命令中的值。
attached()	判断舵机参数是否已发送到舵机所在接口。
detach()	使舵机与其接口分离，该接口（9或10）可继续被用作PWM接口。

2.Arduino舵机实现代码

// Sweep

// This example code is in the public domain.


#include <Servo.h> 
 
Servo myservo;  // create servo object to control a servo 
                // a maximum of eight servo objects can be created 
 
int pos = 0;    // variable to store the servo position 
 
void setup() 
{ 
  myservo.attach(9);  // 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 
  } 
}
