[Arduino] Servo Motor

※ Servo Motor

Circuit

Source Code

Include Servo Library

#include <Servo.h>

Servo myservo;
int pos = 0;

void setup() {
  // put your setup code here, to run once:
  myservo.attach(9);
}

void loop() {
  // put your main code here, to run repeatedly:
  for(pos = 0; pos < 180; pos += 1)
  {
    myservo.write(pos);
    delay(15);
  }
}

※ Servo Motor with variable resistor

Circuit

Source Code

#include <Servo.h>

Servo myservo;

void setup() {
  // put your setup code here, to run once:
  myservo.attach(9);
}

void loop() {
  // put your main code here, to run repeatedly:
  myservo.write(map(analogRead(A0),0,1023,0,120));
  delay(15);
}
