I made a cool game console out of a Meccanoid and Erector set as the frame and I used Sergey Royz code (CHECK IT OUT) and I added extra stuff into it and increased the speed so it moved smoothly. I am not going to explain how to make the frame but I recommend you to make your own frame. But you do need a frame. Have fun with this do what you want. I HOPE THAT YOU LIKE THIS PROJECT! Comment if you have a question and I will hopefully be able to answer it as soon as possible and if you have any recommendations for my next project please comment and tell me. Also my fritzing was not working, so I will just tell you:

Schematics:

Attach the shield to the Arduino Uno so you have more GND and 5v outlets without using a breadboard.

Matrix:

• VCC to 5V Arduino

• GND to GND Arduino

• DIN to digital pin 10 on Arduino

• CS to digital pin 9 on Arduino

• CLK to digital pin 8 on Arduino

Joystick:

• Gnd to Gnd pin on Arduino

• +5v to 5V on Arduino

• VRX to A0 on Arduino

• VRY to A1 on Arduino

• SW to digital pin 2

🛠️ เจาะลึกเบื้องหลังการทำงาน (Deep Dive / Technical Analysis)

The Snake LED Matrix Game is one of the most intellectually difficult, yet satisfying coding projects on the Arduino. Controlling an LED matrix is hard enough, but programming a coordinate-based engine that tracks the growing tail of a snake requires intense array management.

The Matrix Hardware (MAX7219)

Wiring 64 individual LEDs is impossible on an Uno. You use an 8x8 Matrix module with a MAX7219 driver chip.

• The MAX7219 uses the SPI protocol (using DIN, CS, CLK pins).
• The LedControl.h library allows you to turn on a specific pixel effortlessly: lc.setLed(0, row, col, true);.

The Snake Engine Logic

To build the game, the Arduino must hold the entire game state in its RAM:

1. The Grid: The screen is an 8x8 coordinate system (X = 0-7, Y = 0-7).
2. The Head: A variable tracks the snakeX and snakeY (e.g., currently at 4, 4).
3. The Apple: A random coordinate is loaded for the apple (e.g., 7, 2).
4. The Movement: Every 300ms, the Head moves one pixel in the current direction. If snakeX == appleX && snakeY == appleY, the score increases, the tail length increases, and a new apple spawns.
5. The Tail Memory: You must use two arrays (tailX[64] and tailY[64]) to remember the exact path the head took, so the tail follows the exact same path before fading out!

Necessary Components

• Arduino Uno/Nano: The game engine.
• MAX7219 8x8 LED Matrix Module.
• Analog Joystick Module: To steer the snake Up, Down, Left, and Right.
• Piezo Buzzer: For "Chomp" and "Game Over" sounds.
