Arduino舵机控制

普通舵机有3根线：GND（黑）、VCC（红）、Signal（黄）

红色的是电源正极，黑色的是电源负极，白色的是信号线。有些舵机线是红棕橘三色，分别对应红黑白。

#include <Servo.h>Servo myservo;  int pos = 90;  void setup() {    Serial.begin(9600);    pinMode(4, OUTPUT);    pinMode(5, OUTPUT);     myservo.attach(9);   }

void loop() {       char val = Serial.read();        if(val=='z') {       pos+=30;                                 // in steps of 1 degree     myservo.write(pos);              // tell servo to go to position in variable 'pos'     delay(150);                       // waits 15ms for the servo to reach the position       Serial.println(" servo_right");     }  if(val=='x'){   pos-=30;                              // in steps of 1 degree     myservo.write(pos);              // tell servo to go to position in variable 'pos'     delay(150);                       // waits 15ms for the servo to reach the position      Serial.println(" servo_left");}
