手持游戏项目，包括源代码，电路和3D可打印外壳部件 3D模型

This is a complete retro gaming device project. Might be a perfect hobby project or a gift to a friend. It is designed for playing a derivative of the classic snake game. The player directs the snake to eat food appearing at random coordinates. As the snake eats, it gets longer and faster. if the snake eats itself then it shortens. if the snake gets out of the screen boundaries then it appears and re-enteres into the screen from the opposite side but it shortens one step. the device has 8x8 led matrix display module. two buttons for direction control, a piezo buzzer for sound effects. The electronics are very very simple for easy construction on a multi holed prototype PCB. fully functional proteus circuit simulation file is included as well as complete C source and the hex file to program the pic 12F683 microcontroller. full solidworks files complete with their feature tree are included. Easily modifiable as needed.
