Picture of Make a 24X6 LED matrix
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!

Step 1: Getting All The Right Things

Picture of Getting All The Right Things
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

how much cost for doing entire project? pls anyone reply me

It cost me about $25.00 U.S currency
didod made it!12 days ago

Hi All, i made it

thank's to Syst3mx

but 4 columb off

i'll try again

it's possible for 10 rows

sorry for my english

Hi sir. Can this be possibly extended into 80x6 LED matrix.? it will be using 10 shift registers right? if possible, can you please make a code for it? thank you so much. :)

.this is my e-mail.

Hi, I have an array of 8 x 16, what would be the code for it, thanks in advance

bEedjj.0821 days ago

.another question sir. Is it possible to use other pins except 10,11 and 13.? I'm planning to use these pins on a MicroSD card.

It might be, but it is going to be very difficult to do, and it is beyond my understanding.

Sir, can you send us the code for 80x8 led display as we are working on the project for the same. We found your tutorial to be very useful. Please help us for the same.

Mail me on this id:

hello sir,,, can you make 10x20 code for me?,,

this is my email =


I will try, as I only have an 8 row display as of now, I am working on a 48 x 10 display, but it is not finished yet.

bEedjj.0821 days ago

and another thing sir, will it still work if I use BC337 instead of 2N3904 transistors?

It should, the main difference between the two is that the BC337 collector and emitter base voltage is 5.0 volts and the current is 800mA, while the 2N32904 collector and emitter base voltage is 6.0 volts and the current is 200mA.

Sir, Can U tell me how to write this code in atmel atmega32 micro controller using C language.

I am unable to as I am new to electronics and coding myself. sorry.

can some one mail me 48*8 or

tq uuuuuuuuuuuuuuuuuuuu...

I sent it to you.

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

Sure I don't see why not, it would be a small display but it should work.

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,


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

Any suggestions


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

elink53191 month ago

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

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


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

khevcatig271 month ago

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 :))

Sir thank you i already saw the CODE :))
