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");
