Most of you here were probably very familiar with the mobile phone’s snake game, isn’t it? If you cannot get enough with the snake game, would you want to build your very own Snake game here?

In order to DIY this snake game, you’ll have to use 256 LEDs and set them all in 16×16 arrays. The game is at the heart of PIC16F84 microcontroller, where it manages the transfer of four register to display the image of the screen. The device “iron Party” is being intended for the presentation of the picture and keypresses for brokering.

The main purpose of this design is to get the snake game to fit in pocket size. Since the PIC16F84 is only a 13 I/O pins, therefore the free-defined image drawing 256 LEDs consignment consisting of display needed some other components. When a full-screen is maneuvering, it only needed six of the I/O pins.

There is still a problem that you must pay attention here. Since PIC16F84 act is available for only 68 bytes of RAM, the optimization of the code is made entirely of memory-use conditions. As a result, the frequency wills decreases the length of worm grows and the large length is already distracting of the snake movement!
