New to electronics and went almost mad looking for a pullup resistor (now I know duh) but I wouldn't have figured it out without this video, thank you very much. You just gained a new subscriber
Now THAT is how you make a KZread video! Simple, clear explanation with a nice demonstration, good sound quality, good video, not too long, not too short.
I finally got it from your video. Good sound & image quality. And no annoying music in the background! GREAT. THANKS!

Me too, I could see how a pull down worked but not sure on the pull up! This video confirmed I was over thinking it! Thanks also.

Ya. I been meaning to get the idea for a while. I actually thought it was a *type* of resistor. What I dont get is, if it didnt hurt the chip or the input to the chip to be directly connected to high or low(in either state, respectively) then why would the resistor be needed? Granted this was the simplest of examples for learning sake. I would suppose the resistance would be needed in a more advanced circuit or in an automated scenario?

Nevermind. I thought about it for a minute. To keep the circuit in a known state, not in the unknown or tristate from induced voltages.
My analogy for this is: floating is like a screen door blowing in the wind, open/close, back and forth. Pulled down is like when you latch the door's handle closed. Pullup is when you hook or tie the door open to a nail or something allowing the kids and bugs to come and go as they please. A picture is worth 1000 words. I've read about these many a time, but, the visual with the button sealed the deal.

I love your analogy, thank you. Analogies like this really help me to understand otherwise complex subjects. Would you happen to know any KZreadrs that teach electronics in this way?
Thank you for this short concise explanation of this. it makes SO much more sense now rather than reading random documentation that just flies over my head, I get a practical example of what's going on and a concise explanation!
Great video Paul. Thanks for covering a topic that pros tend to think that s too simple to cover, I know it took me awhile to understand what was going on with pull up and pull down resistors. As usual you make it very easy to follow what is going on.
Awsome, the Yoda of electronics explains a confusing topic "simply". Thank you for sharing your knowledge.
Exactly what I needed to know, without flooding me with info I didn't need. Awesome. Thanks for saving me an hour or so of wondering and playing around before coming to this solution!
Thank you very much for making this video! I too was incredibly confused with the idea of pull up and pull down resistors. It's simple, but can get quite confusing when you don't know much. This helped a lot!
What a simple, great demonstration. Thanks for taking the time to make this!
Hope you have been feeling better, glad you still make vids, I love to watch them. :D
This is truly short and sweet. I have been connecting a button to a resistor my whole life without understanding what happens. Thank you for sharing this with us
Finally now I understand the concept. It's amazing how your video made it so easy to understand. Thanks buddy.
well done - thank you. having that dynamic display makes a HUGE difference to the quality of this explanation. Seeing is believing!!!! The best expose of PU PD resistors I have found.
Of all the videos, this is the simplest and best explanation of this topic. Thanks!
I quickly searched "pull up vs pull down" and this was the first result. I have no desire to continue looking at other results. This answered the question nicely :) Thanks for the vid :D
I finally figured this subject out, thanks to your explanation. Thank you so much, I'm really grateful for that.
I had a surface level understanding when you demonstrated with just the resistor but adding the button gave such a simple practical example and made everything click. Thank you for this
Great video Paul. Well explained and easy to understand. Always nice to see a practical demonstration too.
Thanks, Paul I wish the instructors in school could have given such an easy to understand lesson. However, there were no Arduinos or digital displays back then. But it's still the best explanation I've seen, thanks for the video!
Dude, this video clear my mind of confusion. Not too fast, not to slow explanation, just perfect duration!
Fantastic Video. I will be linking to this video often in discussions all over the web.
I watched about 100 tutorials to understand the concept but failed to and each Channel had huge subscription and likes but they failed and here is your channel with very less subscription but got the concept of pull up and pull down right away. U r one hell of a great teacher hats off to u sir. So simple to understand if your tutor knows how to teach and clarify a concept. Your tutorial is the shortest of all yet what others failed to clarify in their long tutorial, u managed to achieve in the shortest yet most comprehensive tutorial, I might send your tutorial to all those and tell them that's how u do it guys, thats how u make students understand like a pro. Amazing job sir, finally I got what I was looking for almost a week now. Keep it up sir.
Seriously- that was well done. Pull Up and Pull Down. Explained VERY well and simply. This is the clearest I've ever had this explained to me. i REALLY get it now. Well done sir. My first time visiting your work and I've subscribed.
Finally I dig it. Thanks for the great and simple explanation - and great showcase using the display!
Thank you so much for a simple, concise, yet valuable explanation!
Excellent, excellent, EXCELLENT visual demonstration! Thanks so much.
That's a great video. Thank you for explaining it in this clear and easy way.
Wonderful explanation! I could not understand the purpose of these pull up/down resistors and even further, why I was getting such varied results with my push buttons until you showed it in this way. Keep up the good work my friend!
Great, concise, easy to understand explanation about pull up and pull down resistors. Thanks!
Paul, just so you know. For me two explanations like that and two math explanations per month and your channel is worth it. Hell, I have even bought products after your reviews. 5 to date. Your good, don't worry about the coming and going folks, just stay with what you know. It will all settle down. Have a good week!
I’ve never fully understood the pull up/down resistor until now, thank you so much for this video.
Great video. No attempt at humor. Pure success at delivering knowledge. Thanks.
Your videos are the best I have seen, Thank you for your help and hard work. Hope youtube is treating you well
This was super useful, have a class and needed to know this. Thank you lots!
You saved me again! Your demos are so good!!!
This helped a lot. So well explain with clear examples. Thanks.
Great video. very easy to follow and great explanation. I will use this with my junior design students tomorrow.
Wow, really fantastic, I understand it well now and can understand the circuits shown in class a lot better now... Appreciate it
So much thankful for this vid! I wanna see more informative vids from you. Thanks again!
This explains so much. Thank you for the video!!
Fantastic demonstration and precisely worded. Subscribed! thank you
Finally I get to understand pull ups and pull downs. And this was just uploaded today! Keep up the good work

Thank you, Sir. You have a very comprehensive video.
The only video on youtube so far that is not confusing on this topic
It makes so much sense now, thanks. I was reading page after page after page of dense explanations and formulas, keep it simple. Now I need a simple one on how to calculate the ohms of said resistor.
Awesome vid, perfectly laid out the logic of why.
Beautiful little video demonstrating the usefulness of pull-up and pull-down resistors.
You explain a lot better than my college professor. Thank you.
Simple and nice explanation. Regards! You are the man.
You definitely got my subscription. Awesome explanation ♥️
Great video, helped me understand pull up and pull down within 6 minutes. Thanks!!!!!!!!!
Thank you for the clear demonstration! I got the official Arduino Starter kit and they started using pull-down resistors with no explanation. It was bugging me why those resistors were there but now I know!
thank you for this simple a clear explanation, it made this seemingly complex concept very understandable :)
Thanks so much for the really short simple explanation. I had known about pull up and down resisters, but for some reason I thought my project didn't need them... Until I went from breadboard to finish soldered project with longer wires, and started getting weird results. Then it dawned on me... I need a pull down resistor. So I watched this video and it confirmed my suspicion. Added a pull-down, problem went away.
Awesome man, clear & concise - thank you
I was getting so frustrated because I didn't get the explanation from neither my book nor any article I found, but this finally did it. Thanks!
finally understood crisp and clear, thanks a ton !!!!
Very simple and well explained. Thank you sir!
Thanks so much, this really helped me understand the relationship between resistors and switches!
I saw like 3 minutes of the video and damn, you're a great teacher. I followed a guide for an Arduino circuit that takes input using a button, but it didn't explain the pull-down resistor too well since the focus was on the rest of the circuit and the code. Just came across your video and you happened to use the same example, which is really helpful! Don't fully understand it yet but I will.
Thanks, Paul. I should have just come here and searched instead of searching all of YT. Fortunately, this was near the top.
Easy to understand, thank you for the info!!!
Cool! Very good explanation. I now have a good idea how it works..... and why some of my projects struggles....
i looked around google for a solid 30 mins, but this vid goes down in my top 2 easiest to understand videos ngl.
Thanks! Im currently reading an entry book about Arduino and electronic and i noticed their use of 10k resistors for the buttons with absolutely no explanation. This has cleared up everything :)
Simple insightful to the point. Thank you!
Thanks mate for this explanation! Great job!
To get rid of the rolling shutter effect on the lcd, dim the room and increase the camera's exposure. This will decrease the camera's shutter speed, which increases motion blur and causes the cycles to blend into one another (just like the eye does it).
very nice sir, thats a lot for clear explanation, complete practical.
Perfect explanation. Thanks!
Thank you Paul another think that I could not understand from anybody else but since you speak the same language I do I finally get it
Good job. Pull-up pull-down understood. Thanks.
This is awesome, Thank you for explaining it so nicely :).
Great, clear explanation. Thanks!
Awesome explanation! Still clear and easy to understand in 2023!
Thank you lots, and I hope you are in good health
Thank you very much, short and sweet explanation indeed :)
Nice lesson, Paul. Thanks.
Wonderful explanation. Thank you.
doing research for my project and kept hearing pull up and pull down resistors. This clarified it.
Thanks. Very clear explanation!
Beautifully explained!
This was so much more helpful than the Arduino manual 🙏
Great explanation! Thanks!
