When you first demonstrated the shift register working, I thought "there's no way this is going to become clear to me in 10 minutes." And then now I'm sitting here thinking, "yeah, shift registers. I understand those." Well done!
I'm starting from mostly scratch with this foray into the realm of microcontrollers (it's been over 20 years since I got my Mech Engr degree). But it's so gratifying when you figure this stuff out. Makes me feel like a kid again. Thankfully I still have my day job! Looking forward to seeing more of you videos! Will stay in touch!
Dear Kevin, recently I retired and, though not educated in electronics, I picked it as a hobby. Until recently I was a complete dummy and despite all other good articles one needs a teacher in front of the blackboard. My goal is to build the 8x8x8 RGB LED cube. But, as I have read, it may not work! So I needed some more understanding of all the different parts and all the acabadrabra. Thanks to your videos I have learned a lot. They Are Fabulous!! Give yourself a pad on the shoulder. Keep going brother.
The first video that REALLY taught me. Using this helped me visualize exactly how to use these, whereas other videos showed me a lot of theory and not enough actual use or vice versa.
good question! it just provided a little debouncing for the clock button, so I wouldn't get double clocking. I didn't put much thought into it, since this was only a demonstration.
EXCELLENT video. You explained it in a way no one was able to explain it on any other video or forum I visited. It's actually quite simple. People tend to start by diving into applications right away without going over the basics. You went over the basics, and now it's for us to figure out the numerous applications! Thanks.
Hi Kd, I've been an (electronics) engineer for about 25 years and have recently watched a number of your videos. I must say you have a very clear way of explaining things and even though I know how a shift register works, I still enjoyed your tutorial. Keep it up :)
I signed up to your channel a week ago and I'm very glad. This video pulled the cloak off of shift registers for me. By setting it up and showing us how it's done manually goes a long way to understanding it. Thanks a lot. Appreciate it!
This was an amazing explanation. I've never really been able to get my head around how these actually work, but this video explained it perfectly. Now I can actually make something with shift registers! Thanks.
are you sure the PI is outputing what you think? and are feeding the 3.3V signals into a 5V shift register? Should still work, check the datasheet's specs
I have played with electronic projects for years just for fun during the long cold winters. I play with the Basic Stamp and A/D converters, temp sensors, easy things like that. I have always wanted to learn how to build and use the basic circuit building blocks that make up a real circuit. Over the years my interest in electronics has faded a 'bit' (see what I did there?). I had to buy an oscilloscope for work and was doing some research when I ran across your videos on the shift registers. You explain everything is such a way that it is easy to understand. I'm excited to watch more of your videos. Tonight's project is to dig out all of my electronic parts and get to work on your shift register project. I know I have some 595's just not sure why I ever bought them..... Thanks a zillion!!
I got an arduino learning kit and have been trying to figure out shift registers all day. This video helps more than anything I've seen so far. Thanks!
Good job explaining how this works. It makes a world of difference seeing it happen physically rather than trusting that what you programmed into your micro-controller wasn't just a happy accident...especially when you very new to programming.
Huge thank you! I went to college in the 80's for electronics and they did not explain shift registers correctly so I never thought I would use them. Now in 12 minutes I learned what I couldn't for the last 30 some odd year. So thank you.
Kevin you did a very good job with this. I already knew all about this shift register but that hasn't stopped me from watching your video repeatedly just to admire the awesome presentation. You nailed it.
Great video once again, I wish I saw this video when I was still wrapping my head around these. I love them too, the limits of how much you can drive from a microcontroller just skyrockets. What would be fun to mention is that you also have shift in registers(parralel in, serial out) so you can have lots of inputs(digital). Hopefully we will learn more on other chips.
Another great video, Kevin! I built a traffic light simulator (4-way with left turn signals for the main street as well as crosswalk signals and emergency vehicle triggered light changes) using four of the 74HC595s... these are great for expanding the outputs of an Arduino. I also used two 8-bit parallel to serial shift registers for the road sensor/ pedestrian crosswalk buttons. Someday I will upload a video with the whole project. I like your videos - they are clear and easy to follow!
Thanks for the clear tutorial! I wanted to mention that I'm using a 74HC595N,112 from Phillips Semiconductor, and the purpose of the pins for 'shift register clock input' and 'storage register clock input' are reversed from what you describe here. On this chip, SH_CP moves the stored data to the outputs, while the ST_CP is the clock for the data shift. It had me pulling my hair for a while.
wow! Great tutorials! Thank you for just putting it in plain English so others can understand you. I watched a ton of tutorials on shift registers and you taught me more in 10 minutes than a host of others did in several hours.
Dude, that was phenomenal! Thanks so much! I've been racking my brain all day long to understand this thing. You've made it so clear. I'm sure there are hundreds of people out there who feel the same was as I do.
Fantastic video! Thanks. The question that brought me here is exactly what you demonstrated at the end, that you fill up the register before doing the latch. So really its like building a frame in an animation. You build a frame, then display it. Other videos make it seem like all you can do is shift one bit on at a time, which would really limit what you can do.
Oh my god thank you, this is the best explination of shift registers I have found on youtube some of the other ones being upwards of an hour without explaining what the pins actually did
I have no idea how such a thing would work on the inside, but this is an awesome way to see the connection between programming and electrical engineering!
Thanks. That was one of the most practical explanations of how the shift register works. I have seen tutorials where they went into great detail about all the logic gates inside and where they have gone into great detail about the complex array of microcontroller instructions that one can use but your tutorial simply showed how the thing works. Thanks.
This is my... I don't know... Probably my twentieth times watching this video. Whenever I forgot how to use a shiftreg, I played this video over and over again.... Thank you for doing this video!
Really nice to see a video, regardless of it being older, talking about shift registers and not including on microcontroller. If you are able to do a lot of stuff without microcontroller than you can just absolutely do killer stuff when you start using them! As a very stereotypical example, just a simple LED Chaser circuit, doing it with couple quad comparator chips , shift registers stuff like that is going to teach you so much more than diving straight into microcontrollers and microprocessors! If you get it even halfway decent understanding of operational amplifiers, latches and flip flops, miscellaneous 7400/5400 series chips or even 4000 series stuff and understand how to combine them together and so on and so forth -- it just allows you quite literally make whatever you want, even with just going a pic16 chip :-)
I have been having great trouble understanding what and how a shift register works until i saw this video. Now i understand better Thanks for putting these together.
This video is truly outstanding! It has made everything so clear. I don't think any other video could match this level of clarity. Thanks for sharing such an exceptional video!
Thanks a lot, man. It's actually quite simple, but it needs a clear explanation. Showing that setup and guiding viewers through the shifting process helped a lot.
Great stuff! Troubleshooting a device and suspect a hc595, which I've never used before, and your video saved me a ton of time. Couldn't have asked for a better explanation!
Kevin, thank you for your time to make such a nice demo. I've just understand whole idea of SR. Thanks for including blank and clear pins that are often skipped in other tutorials.
Beautiful. Before watching this I loosely understood that shift registers were used to store some kind of information somehow. You did such an excellent job of explaining everything and it helped me immensely in understanding how shift registers work. Thank you!
I finally (fully) understand how these darn things work! Thanks for taking the time to make it! Can you explain what you mean by "rising edge" and "falling edge". I think you're talking about high/low, but I'm not sure!
HI there! Great tutorial, built the circuit from your other video. But I had to pull down the clock, latch, and data lines with 1k resistors to stop static interfering with the 74HC595. Drove me crazy trying to find out why it wouldn't work till I found out my hand was carrying a positive charge lol! Useful for anyone else building the circuit.
Thank you so much for this viedo. I did never understand a shift register during my high school and you managed to explain it so i can understand in 10 minutes!! Just amazing. I wish you all the best.
Great video. I just discovered your channel. I love channels like this which don't dumb anything down or skim over a topic so quickly you don't learn anything of practical value like some channels out there. Your channel manages to keep its content very understandable while also being able to go into detail about the topic at hand.
Dude, your videos are awesome! Everything is explained really well and very easy to understand watching these chips work in 'slow motion' using push buttons
wow, now that is interesting! I wouldn't think different manufacturers would swap pins? You might want to triple check that one. Very odd, but it wouldn't surprise me. I guess some manufacturers don't want their parts to be drop in replacement compatible with others? who knows
Excellent tutorial. The LEDs and simple explanation are very helpful. I don't know much about electronics but I know a lot more about shift registers now than I ever did before! Thanks for making this :)
Thanks Kevin. Great tutorial as usual. This helped me understand shift registers. Hope you keep producing these. Your RGB cube is on my list of things to make this year!
THANK YOU SO MUCH!!! ^_^ We currently having a hard time thinking how are we going to configure our Logic Probe project with Shift Register as data memory. After watching this video, my groupmate and I suddenly knew what are we going to do!

buttons are either pulled up or down via 10k resistors, try that before putting in the button LEDs. hope that helps
