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

Hello! I‘m trying to make a 15*7 with 4017 and 74HC595 (and a 2982 to increase the currant) as my intern ship project. It's new to all my tutors(what a bad luck) and i just don't know how to program it with Arduino! Could anyone give me a hand pls! Thanks a lot!!!

I want to make this project, but using 32X7 LED
matrix, can you send me the code for the

Hello! I'm trying to program a 15*7 if you have the code for 32*7 would you please send it to me? I have no idea how to control the LED matrix on arduino.

Thanks a lot!!!

I made it but only 2 rows are working . plz help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Hello.. I want to make the 24 x 6 but i need to control it with C# and PIN 16F887, do you know if I can make this one with those things??

Can you do a YouTube tutorial on your code please? It's a little hard to understand... I'm trying to have a code for 7 rows instead of 6

Hello guys

Can you help me to conect a ultrasonic sensor with 6x24 led matrix please

thank youu

I wanna make this..

Will this led s scatter during day time?? Whether i Can see the display texts during time??

If someone tried this awesome project ..plss reply

I have made a 48 x 8 display with blue LED's, and they are visible during the day. I use a piece of black construction paper over the back of the soldering grid, it helps block out the back light.

I meant the blue led s before

I tryed to simulate this circuit in Protous but the Arduino didnt run. I think there are some wrong in your code.

I'wnated to try it first in ISIS PROTEUS before i going to create but does not work and i can not find fault, so if someone uses PROTEUS please help!

I am first time interested in LED works.I love your abc steps but how do I get the module that will upload data from computer to the LED work.

please mail me to

hi sir, my name Oky Putra, friend of Fazar Ramadan .. that yesterday had you give a sketch to make this project .. we are partners .. we've managed to make it up to 97x6,, it makes us happy., we would like to thank you very much for you because it helps us ... but the thing is, if it could be if we want to create different animation ?? not just scroll to the left .. thanks :) could you reply on my email

icey.hood Okyp1 month ago

let me know, as i need to do animations as well.

I am currently working on that, don't have the solution yet.

how can i know the IC numbers that you have used in the first picture of this step?

Please help me to know the IC numbers.

please can u help me to write an arduino due code program for lighting a combination of matrix 9x6 (LED/speakers) randomly and individualy.
thank you

I am sorry but I can not, as I don't have a Due, and not sure how to program it.

icey.hood2 months ago

Thanks, i too made it, but my display is mirrored and moving in the wrong direction, where did i go wrong?

Sent you a message.

excuse me Sir. Have you used 8 raws? because in the image there are 8 transistor connected to the 4017, can you explain me why, I'm not very experienced...please reply to my email:


Each row is controlled by the 4017 decade counter, so you will need a transistor for each row you have in your display.

well you have 6 or 8 raw? i don't understand

Syst3mx is using 6 transistors for his display, the PCB drawing mistakenly shows 8 transistors, for a 6 row matrix you need 6 transistors, for an 8 row matrix you need 8. Please pm for any more questions, if I can answer them I will. Sorry reply was not clear, I was tired when I made the comment.

need help!
i have made this project using three 8x8 led modules ( total 24x8 matrix)using your coding.
but my teacher is asking me to take data serially from computer and display it on the matrix. Can you please modify your code?

jay.thanki.752 months ago

can i have code for 24 * 6 LED display..????


Syst3mX's code works great for a 24 x 6 matrix, however it will not work for more than 24 columns.
