/*********************************************************************
 * DF Pong Controller
 * 
 * This program implements a Bluetooth Low Energy controller for Pong.
 * It sends movement data to a central device running in the browser and
 * provides audio feedback through a buzzer.
 *
 * Game Link : https://digitalfuturesocadu.github.io/df-pong/
 * 
 * Movement Values:
 * 0 = No movement / Neutral position
 * 1 = UP movement (paddle moves up)
 * 2 = DOWN movement (paddle moves down)
 * 3 = Handshake signal (used for initial connection verification)
 * 
 * Key Functions:
 * - handleInput(): Process the inputs to generate the states
 * - sendMovement(): Sends movement data over BLE (0-3)
 * - updateBLE(): Handles BLE connection management and updates
 * - updateBuzzer(): Provides different buzzer patterns for different movements
 * 
 * Key Variables:
 * - currentMovement: Stores current movement state (0-2)
 * - deviceName : GIVE YOUR DEVICE AN APPROPRIATE NAME
 * - LED_PIN : It is important to see the status of the arduino through the LED. 
      if you can see the built-in add an external one and update the pin it is connected to
 *
