Arduino - Simulating continuous rotation (for standard servos

#include <Servo.h>

const int buttonDecPin = 3; // Decrement button pin

Servo myServo; // Servo object
int servoPosition = 0; // Servo position variable
int prevButtonStateInc = LOW; // Previous state of increment button
int prevButtonStateDec = LOW; // Previous state of decrement button

void setup() {
  myServo.attach(servoPin); // Attach servo to pin
  pinMode(buttonIncPin, INPUT); // Set increment button as input
  pinMode(buttonDecPin, INPUT); // Set decrement button as input
}

void loop() {
  // Read button states
  int buttonStateInc = digitalRead(buttonIncPin);
  int buttonStateDec = digitalRead(buttonDecPin);

  // Increment servo position if increment button is pressed and previously wasn't

    servoPosition++;
  }

  // Decrement servo position if decrement button is pressed and previously wasn't
  if (buttonStateDec == HIGH && prevButtonStateDec == LOW) {

  // Update servo position

  // Update previous button states
