Introduction: Snake on LED MATRIX (BT)

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

Picture of 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.

Hi author,

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!

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.

I followed your steps, and this is result. Did I miss something?

Why You have arduino 1.6 in settings? I will make some movie tutorial for You tomorrow, ok?

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. ^^

Hey Atmel studio is free :)

May I have see your circuits?
Because I am afraid that I follow below scheme can not run with your code.

PrzemekM1 (author)VũK32016-06-13

You must use this pinout:
because I use hardware SPI

VũK3 (author)PrzemekM12016-06-13

May you explain more specific about this thread?
I am newbie so it still has a lot of strange concept. Can I add your skype ID?

VũK3 (author)PrzemekM12016-06-13

Really? Ok, thanks a lots.

Hi there,

I got problem with this instruction. I use Arduino Uno R3 and 4 LEDs Matrix and follow this (because of your image is not clear) and Upload your code in Files.rar, but it present the errors (in the image). Please help.

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.

VũK3 (author)PrzemekM12016-06-12

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.

VũK3 (author)PrzemekM12016-06-09

I thought I can use arduino IDE to upload your code to arduino.
Thank you very much.
