Analog Yet Digital Looking Clock (Whole Clock Rotates, Handle Is Stationary)

We already have the template cut outs. Now, write down the time indicating numbers. I used white cardboards for the body and glued the number sheet on that.

Here is my sample code. You may need to adjust it a bit.

include <Servo.h> 
Servo myservo;
Servo myservo1;
String readString;

int servo1 = 0;
int servo2 = 0;
int startMinutes = 0;
int Hours = 0;
int prevHour = 0;

void setup() {
  // put your setup code here, to run once:
  myservo.attach(9); 
  myservo1.attach(10); 
  Serial.begin(9600);
  myservo.write(180);
  myservo1.write(360);
}

void loop() {
  while (Serial.available()) {
    char c = Serial.read();  //gets one byte from serial buffer
    readString += c; //makes the String readString
    delay(2);  //slow looping to allow buffer to fill with next character
  }

  if (readString.length() >0) {
    Serial.println(readString);  //so you can see the captured String 
    int n = readString.toInt();  //convert readString into a number
    Serial.println(n); //so you can see the integer
    if(readString.indexOf('h') > 0){
      myservo.write(180 - (n * 15));
      servo1 = n * 15;
    }else if(readString.indexOf('m') > 0){
      myservo1.write(360 - (n * 6));
      servo2 = n * 6;
      startMinutes = 1;
    }
    readString="";
  } 
  minutes();
  if(Hours > prevHour){
    prevHour = Hours;
    int newValH = servo1 - 15;
    if(newValH < 0){
      newValH = 180;
    }
    myservo.write(newValH);
    servo1 = newValH;
  }
}

 void minutes(){
    if(startMinutes > 0){
    delay(60000);
    int newValue = servo2 - 6;
    if(newValue < 0){
      newValue = 360;
      Hours = Hours + 1;
    }
    myservo1.write(newValue);
    servo2 = newValue;
  }
 }
