Picture of Make a 24X6 LED matrix
PICT0003.JPG
PICT0021.JPG
After making a 8X10 matrix a lot of people asked me about expanding the matrix to some thing bigger, and some wanted to write stuff to the matrix via a PC, so one day I looked at a pile of LEDs that I had leftover from a LED cube projected and I decided to make a bigger matrix with all the things people wanted.

So what are you waiting for? Get those LEDs out and heat up your soldering iron because we are about to make a 24X6 LED matrix!

So you will need the basic set of tools for this project : a soldering iron, some solder wire, a cutter, a needle nosed plier,some wire, wire striper, and some desoldering tools if you need them.

For the matrix you will:
1. 144 LEDs
2. 24 resistors( The value is determent by the type of LEDs, in my case 91 ohm)
3. 4017 decade counter
4. 6 1KOhm resistors
5. 6 2N3904 transistors
6. A long Perfboard
7. Arduino
8. 3 x 74HC595 shift register
10. some pin headers

is it possible to make and LED matrix with only 20 LED's?

elink531921 hours ago

This is code for a 48x8 scrolling display.

Where can we find the code :O?

Could you send me the code please?

I'm working on a little project with the DS3231 integrated in this solid wooden case with the same matrix. I would want the temperature to be shown too.

Just trying to clarify, the 5V source voltage you got was from the Ardunio board itself correct?

I need a emergency help. I am making 6*56 (6 row, 56 columns) led display project with Arduino uno ATmega328, 8 shift registers (74HC595), Decade counter( HCF4017), transistor ( 2N3904), 1 Kilo ohm resistor. I need the program for the micro controller. Plz help.

The number 5 does not show complete with the exception of all characters. Why??

If the last two rowns dont works in the citcuito, no show for all characteres, but not, the circuit work very well.... ¿¿¿¿...???

#define NUM5{B01111110,B01000000,B01000000,B01111100,B00000010,

B00000010,B01000010,B00111100}

------>> Matirx 48x8 <-------

Any suggestions

Yeah, my error when modifying the code, it works better now.

I hope everyone that is using Syst3mX's code that I modified, would be kind enough to let me know how it is working for them. My email is elink5319@comcast.net.

Hello elink 5319 Give me a code please for make a 48X8 led matrice

Hello,

Can you help me in designing the hardware...for these matrix, do we require each LED a transistor...if not.. what should we do

hi sir can you please give a code thank you sir

Kevin, I have just sent it.

Sir thank you i already saw the CODE :))

To anyone who needs the code for a display bigger than 24x6, I have taken Syst3mX's code and modified it to work with a 48x8 display. The code can be changed to either an 8 or 6 row display with up to 48 columns Contact me and I will send you the code. I am not sure how many columns you can extend it.

send me code for more than 24 column.
09dec049@nirmauni.ac.in

I have sent you the code, have fun.

hello elink5319 I would like the code that you have made, I believe im on the right track to getting it to work but stuck on the

spi_transfer(make_word(0x01000000,k));

please send me your code

the matrix that i have made is a 6 by 40

email Jrsprouls@gmail.com

Thank you

I have sent you the code, have fun.

Hi, It´s great, i´m also making a 48x8 display, but not how to modify the code of the original matrix 24x8, can you help me with the code??? Please...

My mail is: czynight_666@hotmail.com

boganazhapa@utpl.edu.ec

Thx.

Sure, no problem, I am glad I can help.

Hi elink5319, Thx for the code, i have some problem, e.g.

1.) Why use setupSPI();???

2.) In the circuito, Can I replace the 2N3904 to 2n2222A transistor? and

3.) I need to send my menssage from the laptop to the screen via serial, How can I make this change?, i need some suggestions.

THX...

HI all again, Im trying to use a DS1307 for display date and time on the screen, and I use the Wire.h library, but i have a problem.

I can´t display a single character. I observed that the problem is in the use of library (Wire.h),

I invite you to notice this problem adding #include <Wire.h> and that help me Why this error?

Please...!!!!!, Any help..

I could display text sent from a serial port from the computer

Thanks samob and Syste3mX. I have successfully upgraded 24x6 matrix to 48x6. But I'm trying to make 64x6 led matrix. Which part of code should I change to make it work. I am using AVR atmega32 instead of arduino but the code is pretty much same. PLZ Help.
