Every video you create is a masterclass in electronics and Arduino. Your ability to simplify complex concepts is truly a gift. Thanks for being a constant source of learning and motivation.

[@StingerSecSol]

Best video I have seen for this project. I subscribed so I can see more in depth projects like this. Thank you!

[@as_coisas_do_pedro]

Que trabalho impressionante, a luminosidade ficou muito boa, parabéns pelo projeto, talvez eu tente replicar algo desse tipo.

[@AmakyeAnsahKelvin]

Please what is the troubleshoot if you upload the code and you see, only first row LEDs is cascading. Any time I power it on

[@andreialexandru7027]

Man, Great Job! I wish you all the best! I have recommended your channel to some of my friends, btw!

[@EEWave]

Much appreciated!

[@jobbe-wijnen]

Can you include a circuit schematic? The steps after connecting ic7 and then the transistors is so brief it is hard to follow.

[@AmakyeAnsahKelvin]

Please what's the amps of the charger head used that was able to power the whole ICs because each three ICs drain 5V but the current flowing is the case. And also I like your video, keep it up

[@AmakyeAnsahKelvin]

Pls will the display run off well if I use arduino uno instead of arduino nana

[@AmakyeAnsahKelvin]

Hello EE Wave, please can I give Column 1 to the opposite side I mean first IC. Yours is connected to left but will it work if I connect column 1 to right side of the led grid. Thank you!

[@vinayphysics4705]

Please share the circuit diagram, it's request

[@MyOwntuahur]

Me too

gracias

[@ghairobin]

Hi Debjyoti, This is great stuff! You explained it well and links to previous videos are also helpful! I don’t have any knowledge about circuits but was able to connect the dots somehow. Thanks to your pace and way of explaining! I have a query, what if I want to make a large display..say 4x3 feet with static text that I can change using bluetooth or some other way?

[@EEWave]

Will upload soon

[@ghairobin]

@@EEWave look forward to it

[@kritikasaritha1684]

Bro i am making it but with audino uno can you please tell me what changes should I make in the code

[@Enigma758]

I'm concerned that you may be overdriving the 74HC595's. Each LED requires approximately (5v-2v)/330ohm = 9mA. So if all 8 of the 74HC595 outputs are high to light all 8 LEDs of a row, then that's 9ma*8 = 72mA and the chip maximum is only 70mA.

[@g-hamtechlabs2408]

so how do you solve this? coz am also thinking thatway

[@Enigma758]

@@g-hamtechlabs2408 In some cases you can get a way with it, but the 595 is not really intended as an LED driver although but you will find a ton of bad youtube videos where they use it that way, and typically overdrive it. The easiest solution would be to use 470ohm resistors for a total of chip current of approx. 51mA, which would not overtax the 595's chip budget. There may not be any noticable difference in brightness, but if there is, you could use superbright LEDs. Barring that, the other solution using his wiring, is to also drive the anodes with 48 PNP transistors connected to the 595's which drive the anodes. Not a great option. That's why I would have wired it the opposite way as he did in the video. Instead, I would have connected all of the anodes of each row, and the cathodes of each column. That would allow me to use 8 PNP transistors for the anode rows (high side drivers) and 6 ULN2803's for the columns (low side drivers). An even better solution is to use a TPIC6B595 which is both a shift register and low side LED driver. Also, that results in the same number of chips that he used above, but you would still use 74HC595 + PNP transistors for the high side driver for the 8 rows. Note: you can find high side driver chips if you look hard enough and want to eliminate the discrete transistors.

WOW 😲 excellent work

[@nantongozai3704]

Please I need a code for that led display

[@AmakyeAnsahKelvin]

Please can I use arduino uno instead of nano and also is the pin 2 (D2) of nano the same for pin 2( digital pin 2) for uno??

[@EEWave]

Yes you can. Yes, both are same.

[@LizelRodriguez]

Do you have schematic diagram of that project, we will do it for school project

[@scriptdevvs]

Nice work as always :D

[@MaxBillion-07]

Great work done EE WAVE

This project must've taken you days. It's taking me days and mine is half as big. I messed up and put it on veroboard haha.

Wow, how many hours it took to finish this project? Please tech the coding part.

[@EEWave]

It took me 1week. I've given 2hrs per day. So you can say approximately 14hrs. Ok, I'll make another video to explain it.

[@jumbo999614]

@@EEWave Thank you. I'm sure all beginners would love to see your video explaining the code.
