Arduino - 舵机

OTTO机器人+蓝牙模块

重点：

例   Servo

接线：红棕黄（vcc、GND、信号引脚）

进阶：利用 newdata = map(sensorRead,0,1023,0,255);   myservo.write(newdata);   改变舵机转动的度数

sensor = analogRead（引脚）;//模拟信号引脚

newservo = map(sensor,0,1023,0,180);//将0-1023转换成舵机的0-180度

myservo.write(newservo);

#include <Servo.h>

Servo myservo;  // create servo object to control a servo

//int potpin = 0;  // analog pin used to connect the potentiometer
//int val;    // variable to read the value from the analog pin

void setup()
{
  myservo.attach(9);  // PIN = 9attaches the servo on pin 9 to the servo object
}

void loop() 
{ 
  //val = analogRead(potpin);            // reads the value of the potentiometer (value between 0 and 1023) 
  //val = map(val, 0, 1023, 0, 180);     // scale it to use it with the servo (value between 0 and 180) 
  while(1)
  {
  myservo.write(30);                    // 90 sets the servo position according to the scaled value 
  delay(500);   
 
  
  myservo.write(-30);                    // 90 sets the servo position according to the scaled value 
  delay(500);   
 
  }
}
