Hi everyone!

Today i will show you how to make SNAKE on led matrix with BT controller ( everything is better with BT ).

Step 1: Materials

We need:

- 4 matrix modules with max7219 ( I use MOD-39 )
- BT module

- arduino UNO

- photoframe RIBBA from IKEA

- red foil to make better effect

- some smartphone

Step 2: Electronics

Everything is on the pictures :)

Step 3: Programs

I write simple programm for arduino in clear C.

For smartphone app i use appInventor.

Files to downloads are in pictures.

Step 4: Finish

Here is simple movie with game.

I use this led display to create others stuffs like: game of life display or simple image display :)

Visit my Youtube Channel and simple blog.

<p>Hi author,</p><p>I found these error when building your code. Please tell me where I can add these libraries and solve this problem. Thank you so much!</p>
Why You have *.ino files? This is problem with project settings. This is not arduino. Create empty C project to atmega328p and write simple blink to make sure that project settings are ok, then copy my sources. Now you try use arduino libraries. I can send you .hex file with program to test.
<p>I followed your steps, and this is result. Did I miss something? </p>
<p>Why You have arduino 1.6 in settings? I will make some movie tutorial for You tomorrow, ok? </p>
<p>No, it's just an extention, and I do nothing with it. I create a new C Execute project, then add your code file. I'm waiting for your tutorial clip, everything will be clear. Thanks for your support. ^^</p>
<p>Hey Atmel studio is free :) </p><p>http://www.atmel.com/tools/atmelstudio.aspx</p>
<p>May I have see your circuits?<br>Because I am afraid that I follow below scheme can not run with your code.</p>
You must use this pinout: https://cdn.instructables.com/FDP/FCF8/IO36G3Y9/FDPFCF8IO36G3Y9.LARGE.jpg<br>because I use hardware SPI
<p>May you explain more specific about this thread?<br>I am newbie so it still has a lot of strange concept. Can I add your skype ID?</p>
<p>Really? Ok, thanks a lots.</p>
<p>Hi there,</p><p>I got problem with this instruction. I use Arduino Uno R3 and 4 LEDs Matrix and follow this </p><p><a href="http://blog.carr3r.com/content/public/upload/schema-matrix_0_o.png" rel="nofollow">http://blog.carr3r.com/content/public/upload/schem...</a> (because of your image is not clear) and Upload your code in Files.rar, but it present the errors (in the image). Please help.</p><p><strong><br></strong></p>
<p>Hey, my programm is in clear C, not in arduino IDE. You should use atmel sudio or eclipse with avr toolchain. I use arduino only as hardware platform.</p>
<p>Hey friend, I found that atmel studio is not free, but I want another one to be free. Is there any other software can build your code? Please help.</p>
I thought I can use arduino IDE to upload your code to arduino.<br>Thank you very much.
