Servo write - variable

Here's another version, with the servo numbers lining up with the pin numbers

// zoomkat 12-13-11 serial servo (2) test
// for writeMicroseconds, use a value like 1500
// for IDE 1.0
// Powering a servo from the arduino usually DOES NOT WORK.
// two servo setup with two servo commands
// send eight character string like 15001500 or 14501550
// use serial monitor to test

#include <Servo.h> 
String readString, servoname, servo2;

Servo mys[18]; //Now we have 18 servos


void setup() {
  Serial.begin(9600);
  for(int i=2; i<18; i++)
{
   mys[i].attach(i); // was i+2
}
 
  Serial.println("two-servo-test-1.0"); // so I can keep track of what is loaded
}

void loop() {

  while (Serial.available()) {
    delay(3);  //delay to allow buffer to fill 
    if (Serial.available() >0) {
      char c = Serial.read();  //gets one byte from serial buffer
      readString += c; //makes the string readString
    } 
  }

  if (readString.length() >0) {
      Serial.println(readString); //see what was received
      
      // expect a string like 07180 containing the servo position and degrees      
      servoname = readString.substring(0, 2); //get the first two characters name
      servo2 = readString.substring(2, 5); //get the next three characters 
      
      Serial.println(servoname);  //print to serial monitor to see parsed results
      Serial.println(servo2);

      int n1 = servoname.toInt();
      int n2 = servo2.toInt();

      Serial.println("the numbers are :");
      Serial.println(n1);  //print to serial monitor to see number results
      Serial.println(n2);
            
      mys[n1].write(n2); //set servo position 

    readString="";
  } 
}
