Arduino servo code

#include <Servo.h>

servo myServo;

void setup(){
  myServo.attach(9);
}

void loop(){
myServo.write(180); // 180 = forward
delay(1000);
myServo.write(90); // 180 = stop
delay(1000);
myServo.write(0); // 180 = backward
delay(1000);
myServo.write(90); // 180 = stop
delay(1000);
}

// adjust the stop value as needed. I worked with a servo that had to be set to 90.
