Now this is an explanation the way i like it...i was looking for a way to expand my GPIO's for my homebrew pinball machine! it uses over 50 switches so...thank you so much for a clear description!

[pavelkraynyukhov]

It is very simple and good explanation. I believe even 12 years old kid would understand what is going on.

Bravo sister 👍👍👍👍. Iam student electronic. Iam pasion of electronic 🥰🥰🥰🥰🥰🥰

Very nice video just what me and my team need for our next project! Thank you so much!

[Ambrjack]

These videos are fantastic. Very clear and easy to understand. Many thanks for posting!

informative, clear, comprehensive, interesting

Interesting, I've used shift registers for output many times but didn't know they could be used for input.

if you are going to name your pins, rather than declaring integers and trusting the compiler to optimize efficiently (especially if you want to later have the code be relatively portable) please use sized integer definitions to explicitly tell the compiler to do what is proper: "#define PIN_NAME uint8_t(12)"

Very cool - thanks so much. Having blown 2 of 4 inputs on rpi explorer hat trying to read gate limit switches, I might just need this!

3:53 minor mistake, CE needs to stay low the entire time, PE is the one that needs to be turned on and off. You got it right when showing the ardiuno, but it was wrong here. Still great video.

Awesome I have been messing about with my Rpi and run out of inputs and outputs!! Thanks Karen!

Karen - Many thanks! This is exactly what I was looking for to better understand this chip.

I love this video. Great examples. But I am left with one question... When "stacking" two shift registers, it would seem that the 2nd shift register is shifting bits into the first via its DS pin. But we I don't see that we ever tell either arduino to accept serial data in. What have I missed?

[ElvizzV]

Very cool, thanks for the good explanation and examples!
I just wonder why you did not use shiftIn this time, when you used shiftOut last time for the shift register output? 🤔
But I will definitely have to use shift registers in one of my next projects... just have to come up with something that needs tons of I/O 😄

I am a fan of ladies who have passion in electronics and coding. they are rare.

Good vid. A jumper wire kit like element14's part# 2770339 would be a lot better for hooking up ground and Vcc.

Ms. Fantastic your class, congratulations!
Want to ask a question? How to apply this Shift Register in a remote control project with Arduino,
Example: a robot walking forward while moving a mechanical arm?

[xrphobby]

Great video thanks for sharing. Instead of using 3 wires hooked up to arduino, how can we make it wireless? Thank you.

I like your electronics videos, but could you do a quick video on sewing? Maybe reading from a pattern? Keep making electronics videos, there aren't enough of them out there. I'm currently looking to make a capacitive touch button with a cap and resistor. A video on that would be AWESOMENESS! Cheers!

For this application, could you use the 74HC165 instead? I have tried researching the difference between the 165 and 166 and for this project I think it would be ok, but just not 100% sure.
