RC Servo for steering RC cars

In RC cars, It's already integrated with RC Servo that can move from 0 to 180 degrees. But actually it can move from 45 to 120 degrees for steering the angle is fix by gears.

Sample code:

#include <Servo.h>
#define mins 45 //degree
#define maxs 120 //degree
#define center 83 //degree
//Maximum speed for turn steering 10ms
Servo myservo;
int angle = center;
bool left = true;

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(angle);
  if(left){
    angle--;
  }else{
    angle++;
  }
  if(angle == mins){
    left = false;
  }
  if(angle == maxs){
    left = true;
  }
  delay(15);
}

This code will move the servo continuous from left to right and right to left by the limit angle of steering.
