Arduino舵机控制

Posted 2020-07-23

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");
}
