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!

Step 1: 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 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.

Okypyesterday

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 poetraoky@yahoo.co.id

Any way of making animations or flashing words rather than scrolling?

hello,
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.

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.

Thanks. I made it :) . Is it possible work with looping?

would you be able to help me change the program to work with 18x8 ? thanks

i want buy this project, what i do? how much this?

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:

roberto.b0996@gmail.com

FQ1RN4UGCXWR16K.MEDIUM.jpg

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?

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

Jay,

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

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

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

It cost me about $25.00 U.S currency
didod made it!1 month 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. jingG_15@yahoo.com

(removed by author or community request)

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

bEedjj.081 month 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.

nidhi123961 month ago

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.

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

this is my email = danielcliq@gmail.com

thanks...

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.081 month 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 code.....vammichanti40312@gmail.com or devallavamsi@yahoo.in

tq uuuuuuuuuuuuuuuuuuuu...

I sent it to you.
