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

Hi, i have do some modification on your code, i transfer your predefined character into a "updateWord" function. Which mean, to make the led to display "happy birthday" instead of doing this byte your_text[14][6]={BH,LA,LP,LP,LY,SPACE,BB,LI,LR,LT,LH,LD,LA,LY};

you only need to write updateWord("Happy Birthday"); under the void setup function.

i have add another code which it listen to the serial port to change the wording, which you no longer need to reprogram arduino to change the scroling text. =)

niki.hak made it!2 months ago

it works I am very happy

sorry mr niki, i wanna ask u something. did u connect cathode of LED's to GND? or u just connected it at transistors? thank u.

howzit nick... man I've been trying to make this matrix but now I have a problem.... what happens is that I get power up to 4 rows and the last 2 rows remains off, and the 24th column is off as well, I really don't know where did I go wrong. I would greatly appreciate any kind of assistance with this design.

hi. i wanna ask u mr syst3mx. mine is not working properly, even after i uploaded the codes. but LED's was active when i hadnt finished plugging every wires, it was blinking. but when i plugged wire into GND of arduino. it stopped. can u help me to solve the problem mr. Syst3mX?

chiven1 year ago
hi friends, I think Syst3mx have helped us on how to make the 24x6 LED matrix, he's been kind enough to share the code for us, all you can do is just study the existing source code. I know it's not easy but that's the point that we learn. i also had difficult to develop a code of Syst3mx in order to make a 40x8 matrix, because iam newbie in programming and electronics. but after studying each line of code on a 24x6 matrix of Syst3mx, and lot of experiments, finally I could make my own 40x8 matrix... even more than that.. based on source code of 24x6 led matrix by Syst3mx, thanks Syst3mx you are rock!! see my video on youtube...http://youtu.be/WaXMXuJYWos

I agree with chiven, as a total beginner, I used his projects with the 8 x 8 display to dive in and become a pro member of this site. So I owe my thanks to him for his concise instructions on his listed projects. Thank You Syst3mX.

chiven..
can u help me in making of 40x8 matrix.....or guide me plz
i have understood the code but some statements are disturbing me plz
sorry iam very busy right now and dont have enough time to reply, which statements?
your code works perfectly with 24X8 matrix
but if i increase number of matrix and join them as joined previous
the didnt work
even including one more matrix of 8x8
it does not work correctly

are you indonesian?

I just succes with your tutor 6x24 on instructables.
And then, Sir, i wanna make running text with 6x48 led matrix. With other animation moving text (maybe) and clock time display (ds1307).

Can you give me code plz.

Thanks before.

tq uuuuuuuuuuuuuuuuuuuu...

hi bro do you mind sending me the code alias 8x80 led matrix... I will truly appreciate...

I sent it to you.

my email is eng.gachara@gmail.com

I am integrating the system so that the arduino listens to text from a gsm arduino shield... this is my main huddle and It would matter alot olif you could help...

regards,
Steve.
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.

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!!!

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

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 festinnosystems@gmail.com

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

icey.hood Okyp3 months 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.

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

icey.hood3 months ago

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