Design a Retro game of Snake from Nokia using OLED and Joystick.

Creating a Nokia Snake game using a 0.96" OLED, a joystick, and an Arduino Nano is an exciting project. Below are the detailed steps to guide you through the process:

Materials Needed

1. Arduino Nano

2. 0.96" OLED display (SSD1306)

3. Joystick module

4. Breadboard and jumper wires

5. Power supply or USB cable

6. Resistors (if needed for pull-down or pull-up)

Step 1: Setup and Installation

1. Install Arduino IDE:

Download and install the Arduino IDE from the official [Arduino website](https://www.arduino.cc/en/software).

2. Install Required Libraries:

Open the Arduino IDE and install the following libraries through the Library Manager (Sketch -> Include Library -> Manage Libraries):

- Adafruit SSD1306

- Adafruit GFX

Step 2: Wiring the Components

1. OLED Display:

- VCC to 5V (or 3.3V, depending on your display)

- GND to GND

- SCL to A5 (SCL)

- SDA to A4 (SDA)

2. Joystick Module:

- VCC to 5V

- GND to GND

- VRx to A0 (horizontal movement)

- VRy to A1 (vertical movement)

- SW to D2 (button press)

Step 3: Testing and Debugging

1. Upload the Code:

Connect your Arduino Nano to your computer using a USB cable. Select the appropriate board and port in the Arduino IDE and upload the code.

2. Check the Display:

Ensure the OLED display initializes correctly and shows the snake's movement.

3. Joystick Control:

Move the joystick and observe the snake's movement on the OLED display. Adjust the delay and mapping values for smoother control.

Step 4: Enhancements

1. Food Item:

Add random food generation on the screen and increase the snake's length when it eats the food.

2. Game Over Condition:

Implement collision detection with the screen boundaries and the snake's body.

3. Score Display:

Add a score counter and display it on the screen.
