This Arduino project implements a simple PAC-MAN game using an LCD display and push buttons. The game features a snake that moves around the screen, eating randomly placed "monsters" to score points. The player controls the snake's movement using push buttons.

• Arduino board (e.g., Arduino Uno)
• LCD display with I2C interface (e.g., 16x2 LiquidCrystal I2C)
• Push buttons (at least 4)
• Jumper wires
• Breadboard (optional)

• Arduino IDE
• LiquidCrystal_I2C library (I2C_lib-1.1.2.zip)

• Connect a 10kΩ resistor across the GND pins of each Push Button(PB).

=======================================================

• Push Button Signal Out to Arduino PIN connections are as follows:
• PB 1 --> PIN 2
• PB 2 --> PIN 4
• PB 3 --> PIN 7
• PB 4 --> PIN 8

=======================================================

• LCD to Arduino PIN connections are as follows:
• SCL --> A5
• SDA --> A4
• VCC --> 5V
• GND --> GND

=======================================================

1. Connect the LCD display to the Arduino board using the I2C interface.
2. Connect the push buttons to the Arduino board.
3. Open the Arduino IDE and install the LiquidCrystal_I2C library if not already installed.
4. Copy the provided code into a new sketch in the Arduino IDE.
5. Upload the sketch to the Arduino board.

• Use Button 1 to move the snake left.
• Use Button 2 to move the snake right.
• Use Button 3 to move the snake up or down.
• Use Button 4 to reset the snake to the starting position (0,0).
• The snake will automatically blink at its current position.
• Each time the snake eats a monster, the score increases by one and the monster appears at a new location.

• Wire.h: Library for I2C communication.
• LiquidCrystal_I2C.h: Library for interfacing with LCD using I2C.

• counter: Counter for dealying the changing of positions of the monster.
• match: Flag indicating if the snake and monster are at the same position.
• score: Game score, initialized to -1.
• X, Y: Current position of the snake.
• prev_X, prev_Y: Previous position of the snake.
• monster_X, monster_Y: Current position of the monster.
• monster_prev_X, monster_prev_Y: Previous position of the monster.
• snake: Custom character bitmap for the snake.
• monster: Custom character bitmap for the monster.

• setup(): Initializes the LCD, sets pin modes for input buttons, prints initial message and score, and randomizes the seed value.
• loop(): Main loop of the game. Reads input from buttons, updates snake position, checks for collisions, updates score, and displays everything on the LCD.
• blinkCursor(int X_cor, int Y_cor): Function to blink the snake at a given position on the LCD.
