LED Scrolling display board using Arduino with 74HC595 

Much appreciated!

Will upload soon

@@EEWave look forward to it

Yes you can. Yes, both are same.

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

@@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.

@@EEWave Thank you very much. Keep it up!

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.

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