A lot of old video game consoles like the NES and SNES used shift registers for transmitting controller input. When the console wants to read the state of the controller's buttons, it sends a series of clock pulses to the controller, which then stores all of the button's pressed states into a shift register, and it then transmits those bits one by one across a serial cable. Back on the console's side, it reads those bits off of the serial cable back into a shift register to demultiplex the bits into bytes/words.
Brilliant video - It's sometimes difficult to find electronics educational videos that put all the pieces together in such a way. In particular, I really enjoy the animations that you use to show how the components react at different input states. You also speak clearly, focus on important points and structure them really well so something difficult is actually quite easy to understand. Thanks to this video, not only do I feel like I have a better understanding of shift registers, but also flip flops, data transmission and how computers work in general.
I cannot express the amount of gratitude I have for your videos. I consider myself a hands on learner so trying to learn through boring PowerPoint presentations is nearly impossible. Your explanations along with intuitive and creative animations help me understand the material when it otherwise would go straight over my head. I appreciate all that you do and keep these videos coming! :)
Ii just got a MB 102 Kit. It's the first time I heard of Shift Register. Thank you for the video. So far the clearest I've watched. Keep them coming... Novice Amateur Radio Operator Learning Electronics
Finally a video on this where arduino isn't mentioned. I'm trying to read serial data from another IC rather than an MCU. Hopefully I can do it with the 595!
Verdade. Já tá chato a gente fazer uma pesquisa sobre um determinado CI e no meui do vídeo Arduino aparece 😂. Não tem pelo menos outro MCU pra eles [Brasil]
The videos are great. I really like how you explain everything. It seems always so clear and easy. I will work again on my projects. Thanks for the quality and the good explanations. (Sorry for my english; it is not my mothertonge)
We need to practice with LED 7 segments display or with led matrix display to understand better the shift register. Dronebot workshop man showed the use of shift register in practice.
My class uses "Digital Design" by M. Mano, M. Ciletti. The book defines latches as triggered by a HIGH value where as flip flops are triggered on the positive or negative edge of a clock signal. The positive or negative edge of the clock signal used for the flip flops is actually just a very short impulse of a signal caused by clever manipulation of gate delays.
i don't really understand why there is so much debate about a Latch and FlipFlop, where the answer is so obvious; a latch is transparent to input all the time when enabled so its a Level sensitive, while a FlipFlop is Edge sensitive meaning its input is reflected by the output at the edge of a clock (high or low). so what you are describing is simply a FlipFlop....
Where do you find these Gate Diagrams? I can never find them anywhere! Is there a certain book? I was hoping to get them for most of the devices that can be attached to an arduino.
So a flip-flop is literally a switch that stays in one position until switched to the other position. And "high" would be the application of finger pressure on a light switch in that analogy.
Hi Karen, could you please do a few videos on the Teensy 4.1? I know it's kind of old, but the code is Arduino. I was hoping to see a shift register connected to a Teensy. Perhaps using the Arduino game controller library, a Teensy could be a controller?
The difference between Flip-Flops and Latches, "Flip-Flops are edge-triggered or edge-sensitive whereas gated latches are level-sensitive (Digital Fundamentals 11th P. 381)."
Porque que só agora que eu tô vendo esse teu vídeo, explica tudo bem detalhado. Eu não entendi muito o que vc falou mais por causa da animação eu consegui aprender de primeira. Agradeço. 👏 [Brasil]
This is so confusing! What would make it much easier to understand is answering the question why at every step of the X explanation. Giving an example of when each register type would be used, would really help me understand what each one does the signal path of each.for example, which option is for one pin on an Arduino sending code for LEDs. And which option is used to send multiple buttons to one pin on there or do we know?
in basic terms SR latches are simpler flip flops. so think of it like this from simple to more complicated you have SR latches then D and T flip flops and finally JK flip flops. they all have their own usage and if you want to learn more a simple comment isn't enough.
Whaaaaaat? When did Sarah Silverman's non-annoying sister start making electronics videos? She's all the good qualities of her sister but without that "I need to punch you in the face, right now" voice and entitledment! subscribed.

Thank you teacher.I understand clearly about Shift Register by watching your video.
The videos are great. I really like how you explain everything. It seems always so clear and easy. I will work again on my projects. Thanks for the quality and the good explanations. (Sorry for my english; it is not my mothertonge)
Thank you very much, when I was looking for shift registers I was always confused by the 3 clock pulses, thank you!
French guy here. Thank you for your videos. :)
Excellent explanation on an underappreciated component !
One of the best videos I've seen on this. Thank you!
Thank you so much. This is so clearly explained! Gonna use this to build a nixie tube timer!
thank you mam keep on making videos it's easy to understand when you show us what you're are talking about practically
Thank you! You are great. Way better explanation than my professor
I enjoy this series of videos. They are very helpful!
No no no.... I was just smiling while watching this...... Wow... The explanation is wonderful
Excellent explanation and graphics! Thank you!

Very helpful series on shift registers. Many Thanks!
A good summary with animations on shift registers.

Once again thank you so much for helping us learn better in an amazing way, Thanks a lot. wish you the bests ever
so so much better than the old videos
OH!
You ARE very wonderfully educate!
a really good explanation, thanks ;)
Great Work. Thanks for your passion.
brilliant video!
Thank you! Nicely done.
Thanks for sharing!
Great video
Superb video! The animations are spot on and clarify a great deal of information. Thank you!
Great explanation mam 🙏thank you .
My last brain cell died
you just saved my life
Great video, thank you very much!
Where do you find these Gate Diagrams? I can never find them anywhere! Is there a certain book? I was hoping to get them for most of the devices that can be attached to an arduino.
So superbly delivered, so many thanks..
Thanks for this video
So a flip-flop is literally a switch that stays in one position until switched to the other position. And "high" would be the application of finger pressure on a light switch in that analogy.
This is mind blowing
Super explain thank you 👍
Can you please fix the learning circuit playlist so its not backwards please
There is a difference between flipflops or latches, the first is edge activated and the latter is clock-level activated.
Hi Karen, could you please do a few videos on the Teensy 4.1? I know it's kind of old, but the code is Arduino. I was hoping to see a shift register connected to a Teensy. Perhaps using the Arduino game controller library, a Teensy could be a controller?
Helpful 💯
Thank you very much :)
It would be nice to see an example on a circuit board
understandable approach ! thank you for your energy + knowledge + moral- sprite
on my way to barely avoid F in microprocessor class.
Don’t get bogged down by the individual logic gates of the shift register combined together
The difference between Flip-Flops and Latches, "Flip-Flops are edge-triggered or edge-sensitive whereas gated latches are level-sensitive (Digital Fundamentals 11th P. 381)."

Tank you very much
Took me a few hours to research how a monitor cable can send individual data to millions of leds on the sceen, now I know it's shift register.
But what is the durations of individual clock pulse ???? if enable pin is on for long time then data input will be same in all flip flop in series
For 595 what pin is the sh/load
This is so confusing! What would make it much easier to understand is answering the question why at every step of the X explanation.

faham faham mekasih😄😄
I guess with pipo you can create a digital sample and hold..
Some important things...
- connecting wires must have dots
- missed a very impotrant thing: what happens when both set and reset are active
Is there a book that explains all this? With maybe some exercises
Thank
Lovly you... And your channnnel
There are only few Karen as sweet as her.
You Rock !👌👍
nice
Can I marry you already 😍. You taught me what my lectures couldn’t ⭐️
Hi Karen
sent me an update if you have it Thanks you
How many other people came here looking for vegetable gardening videos?
none

Lady, do u have a dr degree?
Flip flops are edge triggered and latches are level triggered, end of story

I learned serIAL not seIES
Am I the only one who doesn't understand a single bit of this video?
lesbian?
you are very beautiful
