8x8 LED Display Oldschool Snake game

Introduction

I decided to create an old-school Snake, because I wanted to learn Arduino in a more advanced project using many components. At first, it seemed to be really complicated, as I was new to Arduino, but at the end I realized that it's not complicated at all, as I got used to how Arduino and it's components work. My version shows the current score on the 4-digit display + play music before and after the game. Of course you can loose the other components and make it just clear Snake game, I think the changes in code would not be that difficult.

Uploading .WAV files to SD card

I spent most of the time figuring out how to play WAV files from the SD card in the speaker. I came up with a solution that worked for me.

First you have to convert the sound file (mp3, wav...) to a specific format. For that I used this online convertor

Other settings unfortunately did not work for me.

Wiring

There are pictures how I connected all the components. I am sorry there is not a scheme, I think it would be more confusing than anything else. I used Arduino Mega 2560 as I mentioned before, but it is surely replaceable by another type. You will just have to figure out where to eventually connect the speaker or the SD card, because the pins will probably differ.

Code

I will not talk/write about the code here, because I have many comments in the code itself

Conclusion

In case you are trying to reproduce it or you are working on something similar, do not hesitate to ask me anything. I will be happy to help, if I will be capable of doing so.
