2:17 - You know that resistor does nothing in that location? the power rails on the breadboard are on split in the centre where you've already got your jumpers. Other than that great tutorial :)
Hello, SiniTronics! ♥ Yeah, that's a huge oversight on my part. I kept wondering why a couple of the LEDs are dying on me. lol. I forgot to remove the hookup wire. :D Thanks for pointing it out! Much appreciated.
Figured out what the issue with the 13CNONKE4 ICs on the testing phase was while re-watching the video [6:35]. Apparently, I did not connect the other ground rail of the breadboard (where Pin 8 (GND) of the IC is connected) to Arduino Ground. I didn't even bother to check, because the other ones are working flawlessly. lol. Holy Crap, that was embarassing.
My only concern is you directly power the LEDS from the board. Which overtime results into a Fried Chicken 🍗 by drawing to much amps. Can't you use a external power supply like shields?
Since there are so many leds and each led draws 20ma, don't you need external power source? I was going to use 2 shift registers with 16 leds then i remembered people talking about how much current Arduino UNO can provide and how much current Led draw. Now i'm searching internet for information. I don't want to kill my Arduino UNO.
Hello, Paul! Thanks for the comment! ♥ IIRC, the 20ma draw is just the most common and is not the standard. My suggestion is to try and find out the rating of your LED your self by using a multimeter or taking a look at websites that are similar to these: www.ohmslawcalculator.com/led-resistor-calculator www.petervis.com/electronics/led/led-resistor-calculator.html www.gammon.com.au/uno But, of course, you can always use a separate power-supply to stay on the safe side of things.
Hey Sir, great work/demo! Have you tried using Mr. Bellavance HC595 library for LED matrix animation? Let's say an 8x32 LED matrix to display animation patterns (not scroll text)? I am trying to replicate the examples in your demo here for this matrix but so far no success as I can only do for one row (or one column) at a time, Any ideas/suggestions will be highly appreciated!
Hello, Scanito! Thanks for the comment! ♥ Sorry. Unfortunately, I haven't tried it on an 8x32 matrix yet, because I have my ws2812b matrices for that. But, try searching for the term "multiplexing". I think it's going to help you do what you want.
Hello, Arjun! Thanks for the comment! ♥ For that, I would point you to this forum from eevblog. www.eevblog.com/forum/beginners/how-many-shift-registers-can-an-atmega328p-actually-drive/
If you want to send different serial data to each register, would you still daisy chain their clock and latch pin, and just connect each register's own serial in pin to a different pin on the arduino?
Hello, Yuxuan! Thanks for the comment! ♥ Unfortunately, I don't have the required knowledge to answer that question. Sorry about that. However, I would like to suggest seeking answers on either of the following: Arduino Forum: forum.arduino.cc/ Reddit: www.reddit.com/r/arduino/ I believe there are people there who are way more knowledgeable than me.
@@HeathenHacks cool thx! I’ve been looking for answers as well. The way you chain them, (serial out into the serial in to the next one), would send the same serial data to all of them, is that correct? I wonder if I could achieve independent control by hooking them up your way, and send a 32 bit data to the first register.
Yes. It does send the same data. Hmmm.. I think this link would help you: ruclips.net/video/6fVbJbNPrEU/видео.html It's an in-depth explanation on how the shift register works.
@@HeathenHacks i did everything as u did in video but when i extract folders are different. Can u contact me on discord milab#3888 Or ig dsava_9 and help me? Its not a problem i can pay you.

@@HeathenHacks ok thank you for honest guide.
how do i add external power supply for the led
great video
I use a cr2302 coin cell battery to test leds. It's way faster
Good work buddy, am lazier than you are but want try this project out with a attiny85 to drive 40 rgb leds, should see how it will turn out
thanks! yes, trying it on an atTiny would be awesome.
Thanks
