hey everyone,hope you are doing fine.
here in this video I am going to make a large LED scrolling text display board.
LED scrolling text display board is a really useful project for your home and shop. Every one can make this project easily by following the steps in the video. also you can play by uploading different examples.
This project will deliberate on displaying a scrolling text message on a home-made 48×8 LED matrix ,you can also use 6 numbers of 8x8 LED dot matrix . The microcontroller used is Arduino nano .The 48 columns of the LED matrix are driven individually by six shift registers (74HC595), whereas the eight combined rows are also driven by a Shift register(74hc595). Here we will be scanning across the rows and feed the column lines with appropriate logic levels. The program in the microcontroller is to determine the speed of the scrolling message as well as Message what we are going to display. The technique will be demonstrated for right to left scroll, but can be easily implemented for scrolling in other directions.
Things needed to make this large LED scrolling text display board:-
1) 2x hard cardboard sheet
2) 1x perf board(zero pcb)(bit.ly/2qfDuGS)
3) 384x 5mm LED(red)(bit.ly/2JjjKLp)
4) 1x Arduino NANO(bit.ly/2z784qh)
5) 7x 74hc595(goo.gl/TZf96H)
6) 7x 16 pin IC holder(bit.ly/2D8aDgj)
7) 48x 100E resistor(goo.gl/81bqv5)
8) 8x 1k resistor(goo.gl/81bqv5)
9) 8x 2n2222 transistor(bit.ly/2CMPkzE)
10) 2x 7805 voltage regulator(bit.ly/2EVZTDA)
11) 4x 10uf capacitor(bit.ly/2yBzKEp)
12) 1x dc switch(bit.ly/2D8jLlc)
13) 1x dc power jack(bit.ly/2Q1grLs)
14) 2x 40 pin male-female berg connectors(bit.ly/2AujXIS)
15) 1x heat sink for 7805

Very cool. Great work, I know what I am building next...
sir your scorlling text video is beter than other scorlling text videos(100%)
Very nice video, thanks for sharing, like
Very well explained. Thank you. Lots of respect from Pakistan 🙏
This is so cool, I want to build one someday!
Awesome bro!!!! 😘😘😘
awesome to see Congrats and great work
I have a few questions about the schematic for the 7805 voltage regulators an the capacitors. This is my first electronics project. 1) does the pin 16 wire from the first 3 ic’s connect directly to pin 2 of the 7805, and also to the capacitor which then goes to ground? 2) do i connect pin 1 (VI) to the 9-12V power source and connect pin 1 to the capacitor, then the capacitor to ground? 3) I’m using 3mm LEDs on my version, and curious if you think i could just use the 5v power from the Arduino (I’m using the uno instead of the nano) instead of using the 7805’s with the 9-12v power supply? Love your videos! Thank you!
Beautiful..
This is amazing. Great job!
Thank you
I am planning to make one even bigger using max7219 ics ...stay tuned
Great job dude it takes so much
Good Job. Thanks
I want to thank you for the time you took to send me the code, and it works fine
Please send me the code too...my email is skidkev@gmail.com. Thanks in advance.
I too need the code....can you send me please @ kumarmathan0603@gmail.com thanks
Very cool sir .......... continued
Nice one there,
Nice project👍
hello brother, can we add few more led lines ,does it need to change the circuit by adding the extra led lights and how can I connect to ac circuit ,which type of adapter I can use
How did you get that type of ribbon cable to separate. I can't use them without an idc connector.
Great stuff! I hope I can make one of these soon.
yeah it's really easy to make and fun to play with.....but be careful while soldering
One I can't understand pliz give me whatsapp no let me ask one question only
Do I need to connect the ground pin on the arduino nano to the -ve
Nice video
👏👏👏👏👏👏 Excellent work of all standards. I have built it and it is working perfectly. Sir,the connections for the row driver to the arduino provided is perfect. Pin14 to D7,pin11 to D5 and pin10 toD6. Changing these connections will result in either last row or first row not displaying meaning 7×48 will be displaying but with your CREATIVE STUFF minds connections, all 8×48 fully displaying. Thanks Sir,keep going and may Allah bless you and increase your knowledge.
passbook
great work
Good 👍
Hello.here the codes i have are designed for common row anode matrix,is it going to work with common row cathode just as you did? Can you please share the codes with us,that is what's missing.i am patienntly waiting for your answer.thanks
Very good job man
Nice video.
Nyc.... Very good tutorial......... Thanks
Great man...this work...thanks man🙏🙏🙏🙏
what is the battery capacity you have used?
i am using a 5v DC adapter
Is the dc jack used to power the 7805 circuit AND the vin pin on the arduino?
Dc 12v comes through the dc Jack...which provides 12v to 7805 and arduino
Hello thanks so much for your video. i made one display like urs and i have a question, hope you can help me. my display shows 63 letters after that number text cuts, how can i do to increase to 128 letters for example??. i am using arduino nano. thank you so much for ur help.
THANKS A LOT NICE
Very nice
Do I need to connect everything that is ground together?
What does the circuit look like where the power is inputted from the dc jack
Very very nice video
Great great and much more great
Thnx
Really very nice project 👌
Thnx
What is the power supply that you have given weather it’s AC or DC and in which way you have connected can please tell me I am doing this project .
Seus vídeos são muito bons.
Nice video.👌👌👌👌
very nice video. you are awesome. may Allah SWT give you Hadaya, and direction to right path. Ameen
Great video!!! I would love to know if at89c52 can do this. If it can I would like to get the circuit diagram and the assembly code. Thanks!!
Really great one with adrino technology and if possible can I get one similar to this as right now I cannot afford from shop and if you can make it with reasonable price, I will get it to place outside for my shop. Thanks in advance.
I made this but problem is row 4 are alowese shifted. circuit is as shown in your video but I cannot find out the problem . I am using 5v 2amps adupter so I am not using 7805
For power supply witch wire i have to connect for 7805
I like the video's that you speak, rather than the music ........Cheers
I have made one similar by looking at your design. Working perfectly fine. But can you please tell me how to display numbers and small alphabets? The code has only capital letters. Also how to add BT-HC-05 Thank you :) Keep the great work ahead.
Possible to Simulate in proteus? Thanks
brother accidently i have switched the anode and shot all of them that means i switch the row and column opposite as you said what will i do now help me
I haven't used it before, so I wanted to add other characters like. /-=?":().so how do I calculate it, or do I use BCD code? Or is there another way
How will I have to change the program if I change the txt.....and plz can u guide me in how to install the Bluetooth module for this.....I need ur help......I want to make this as my project....
Nicely done!
Good.

Hi whats the name off those 48 resistors u use
This project helpful for noticeboard also..Sir this board can we use as wireless
Great I build all hardware and its work but one row not work, I think this is a code problem, can you help me for right code
What should be the resistor value if I will use green led
plz make vedio 16x96 runnig led board.....can we increse ic for more large board
Nyc video....
I would very much like to build this circuit I have no problem in electronics in the program I have a problem programming the Arduino could someone help me with the program?
like nice
frst of all th ku so much sir... u r a grt hlp to me 😎😋 ... sir ek question tha agar board ka dimension ho 4*1 (feet) toh power supply pr ya baaki kis cheez pr it vl have its effect ... pls rply asap sir vry urgnt 🙏... thnku in advance
This method of connection and 74hc595 are not good if you are making a board that big...use p10 boards instead or max7219 ...and yes you will be needing a bigger power supply
@@CreativeStuff thnku vry much sir 🙏 and how much big power supply is needed ft the purpose sir ...
12v 5amp will work fine
Super
Can you tell me whats the reason to use 1k resistor
how to add dynamic clock without scrolling? thanks in advance
Very interesting job 🙏 good evening sir
So nice of you
Bro for this project 🙏🙏 really appreciate u I purchase this parts For this circuit it take 7 hrs without rest For keeping hols it take 1 hrs For soldering 1 line it takes somuch of time and it feel boored Real see now this project is side of me soldering rod is also on i started to do now I complet line it's booring now I am watching KZhead Great for ur work
Thanx for watching...but its not boring for me ..rather it's interesting
👍
Need could of audino not avilable
What!!! Did you say soldering part make you bored🙄🙄
Audrino power supply in where?
Do I need to connect the ground pins on the arduino to the common (-ve)
No..you don't need to..
Sir can i make 8×60led metrix by using this Code
Its work 😍😍 tq bro ❤️
Can You Send Me A Photos Of Your Project Which You Made My Email I'd Is kalariyaparth7@gmail.com
sir making a digital clock by connecting DS3231 clock module this display proper
Patient man. :-)
Great Gadget
If i was to do this with green LEDS instead would I need to change the resistance, as the red LEDS require 1.8-2.3 volts while the green LEDs require 2.8-3.6 volts
Any resistance value between 100-470 ohms will work...but make sure every single one of the 48 resistors are of same value
Can you upload led matrix library
Hi again MR CS,can you can please tell me where the arduino nano gets the power from?so as to drive the Row Shift register(IC),because on the diagram ,the two voltage regulators are only for 6 ICs. What if we add another voltage regulator in pararell to the others in order to drive the nano,and encrease the Vin to 16or 20? I'm waiting for your answer,thank for all creative stuff you share.
Nano gets power directly from the input power and the 7th ic gets power from Arduino Nano ...yeah you can add another 7805 but connect it to 5v pin instead of vin pin of the nano
Okay thanks Cz
So we don't need cd4017 in this circuit as i watched in your wireless display? Or no need of it
No need of CD4017....only 7 shift resistors 595
okay,how can we modify the codes so that we print out the numbers on the display as well? or the circuit is only for texts?
hola disculpa, como hago para poner numeros?
Very nice bro 👍
Thanks for the visit
@@CreativeStuff ok
If you want letters in Marathi, if you change the program, will it work?
Hello may I ask, if the +5v of column driver and +5v of row driver are connected to 5v of arduino? Thanks
No...row drivers are connected to 7805 regulator...column drivers to 5v of arduino
+5v of row driver to 9-12v of 7805 circuit? 😅
@@nerwinalamas1334 7805 gives 9-12v output?
I'm unsure where to connect the 5v of the row driver, which part of 7805 circuit?
Need bootload in other chips?
Can I buy complete cercuit board and let me teach
EASY .
sir will you please send me the link of complete circuit digram ...... for better understanding i need full circuit digram of it ..its difficult to understanding in parts plzz send full scmatic digram...
वीडियो बहुत अच्छी और इस सर्किट को बनाना आसान है। Thanks for the video. प्लीज एक 12 hour LED clock arduino uno के साथ बनाये। बिल्कुल easy steps के साथ। I am waiting for the video. Thanks in advance
8*72 ke liya keya change Karna parega.
hello sir, thanks for this video. If I want to use Arduino uno what changes need in circuit and program? Please help
No changes needed...every thing will remain the same...I think there is no difference between Arduino Uno and nano except the size of both
thank you so much. Do you have any idea about 48x16 led display? how to make it, circuit diagram and code?
No idea 😁😁
Ok😊
Please bro I am unable to open that Arduino code on my mobile phone .... Is there any application to open or read that program???? Please Help
Please Sir, for the row driver diagram,pin 11 of the ic 74HC595 was connected to D6 of the arduino nano while pin 12 of the ic 74HC595 was connected to D5 of the arduino nano? Please Sir shouldn't it be pin 11 to D5 ,pin 12 to D6 and pin 14 to D7?
You can change the pin-nano digital pin connections according to your code
Hi sir I want to order 8*8 scrolling display
