Not talking to a wall. Actually watched the entire video. Good job again, Paul. Thanks. Love your series.
true...but when you think about he really is
@@anews4898 he is talking to camera.
Definitely second this post. You are a great teacher and you make me laugh a lot while I’m learning along. Thank you!!
Me too
Lessons are great! As someone who loves to completely understand why things do what they do I really appreciate you going through the math on this instead of just saying "Put these numbers in and it'll work". Keep up the great work and I'm having so much fun learning how to do this!
My pleasure!
When i bought arduino i couldnt even turn on an LED. Thanks to you Paul i now can do everything you taught me.
P. S im 13 years old
im 11 and im learning soo much for him
im 12😜😜
@@anews4898 im 11 too
Same! I love these videos
im 69
I got my Arduino only five days ago but learned already about dimmable LEDs. What a great lesson! Love the integration of circuit design, math and coding. Wish this kind of educational stuff was available when I grew up. It gives me confidence that our grandchildren won't have to plow through boring electronic books. I think when I am done with all your tutorials (hopefully by the end of the summer) , you will succeed in getting me "to think like an engineer". As the Chinese say: 活到老学到老, never too late to learn. I am 74.
Keep it up fire
I have ADHD and getting started seemed very daunting until I found your videos - I'm following along, doing all the homework & trying stuff out when I finish. It's a lot of fun. Thank you!
Paul, your videos are amazing, and you are a great teacher! I’m a chemical engineer, but never did match with electrical or coding until my current job. I’m now doing plc programming and wiring up level and pressure, transmitters, et cetera, There isn’t much good information on the Internet in terms of basic instruction. My son as a freshman electrical engineering student and had a semester project based on the Arduino last year. After watching what he was doing, and realising how similar it is to PLCs, I bought a kit and started playing around with it just to get more familiar with electrical and coding. Then I found your tutorials. You have a great mix of immediate hands-on instruction, but with the math and physics mixed in. I find most tutorials limited in value because they mostly just do the hands-on part. So far your progression of skills has been spot-on.
I'm a10 years old and when you said linear equation I was going to quit but you explained very vell that I little bit understood what is linear equation thanks for such tutorials
im 11 and i enjoy is tutorials to!!!
Hey I'm ten too!
Nice job. I'm currently 13. i bet when you become 13, you will be much better than what i was at 13. keep going. and if you have not watched the 13 other episodes i REALLY recommend that.

Keep it up buddy. I am in college now and if you're still interested in Arduino and Raspberry Pi you could pursue Internet of things technology and embedded systems!
Hi Paul! I was a 13 year old teen bored at home this summer in quarantine ... I randomly found your videos one day and instantly had to get an arduino super starter kit. Trust me you are not talking to a wall at all. I 100% consider you a teacher and more, always making sure to do that homework! Thanks for giving me and many others something fun and exciting to do this summer :).
These lessons went in just the way I was hoping! Right as the potentiometer was introduced, I had the same idea.
Great!
Paul, you're a great teacher. You're not talking to a wall. I'm actually learning practical engineering from you. I'm an aerospace engineering major and hope to learn more about electronics from your series. Honestly, you made my day when you said, "I want to teach you engineering." Thanks a lot for your effort!
I am really happy. I only listened to the beginning of the problem, I paused the video and managed to do the project and the code without having to watch the whole video.
After that, I watched the whole video and realized that my reasoning was correct.
Thanks again teacher.
A hug from Brazil
Return Hug to you!
Thank you Paul, you are a great teacher, being a former Instructor in electronic technology for 13 years, and understanding how valuable it is for a student to have the lessons broken down practically and with examples, it allows me to recognize the quality in your instruction!
Wow, thanks!
i do the projects, and the homework. I love where you have taken the series. Occasionally I do find myself yelling at the screen when i see a mistake lol, but you always catch them and usually before I do. Great job thank you for your hardwork!!!!
I am an electrical engineering student and have learned more watching your videos than I have attending classes, so please keep up the good work.
Paul McWhorter, I was looking around on your channel and it seems like I will be hanging around for a while, almost all of your videos are things that I am interested in and want to learn. I hope going forward you will keep putting out great content. Thank You, Richard Monseglio

The best channel to study electronics , perfection in every video .
Great lectures Paul. They are better than all of my Arduino books put together. I'll stick with you and do all of the projects. I'm 73 and a retired engineer (UK) but have always struggled with digital electronics. Regards.
You are not talking just to talk. I watch the full video and do the homework assignments you give out. This series has been really helpful and I appreciate all the work and time you put into it.
Wow, thank you!
Ditto!
The point you made from 6 mins 30 seconds onward is what i feel makes you stand apart from other and a great teacher. To understand something truly we should know it's building blocks, now there might be a short cut to get to an end result but leaning on short cuts doesn't help in doing something substantial in any field. Thank you Sir, your videos are helping many a guys like us learn amazing things! ❤️👍
I'm still watching these videos. I'm learning quite a bit. I've had Arduino kits before, but I'm learning so much more in these videos instead of just following projects. I did the homework project and was successful!
P.S. I don't drink coffee at all.
Hey Paul, your videos teached a 37 old man (that's me) to make a dimmable LED during COVID-19 days. And thanks to you I'm now a Caffeine addict LoL.
Good that you explain the Math and not only showing the Map function. So anybody knows more what the Arduino is doing in the background when useing the map function..
Thanks again Paul, I am enjoying every moment of your course I am on lesson 14 now and must say I am learning a lot. You are the best Teacher ever.
Great to hear!
I watching this video on 22 April 2024 and I have watched the whole video and learn enjoy both. Love from India
I just turned 64, and before these videos, I couldn't even spell LED, and now I can turn them on and off.
Seriously, you are helping me figure stuff out so I can light my model spaceships and do cool things. Thanks, You ain't talking to a wall. 64,342 views!
I actually sit and listen to the whole video. I need to spend more time with you. I absolutely love the videos! I love the math, engineering, physics, coding, circuits, etc.
Thank you for such a wonderful series!
YES , YOU ARE ACTUALLY HELPING ME TO LEARN THIS VERY ACTIVELY!

Another great video. You certainly are not talking to a wall. I appreciate your in depth instruction and all the math. Most other instructions assume far too much and you get nothing out of it. Yours is composed of true in-depth lessons and not how-to hacks. The majority of the comments below reflect our appreciation for your quality instructions. Please keep up the great work in providing these wonderful lessons.
I'm an old guy (69) who studied electronics when vacuum tubes were in vogue. (long time ago.) I built my first digital circuit with simple switching transistors , capacitors, resisters etc. My first chip experience was with the NE555. (also a long time ago) I'm studying along with you and am on project 144 as I write this. I am fascinated with micro processors and their uses in hobby projects. You asked if anyone was out there? YES! I'm here. I've programmed some in BASC but this is really quite different. (to me) I enjoy the course and am committed to the end. Thanks for producing it.
Never knew the day when I would actually understand and be able to do what a teacher did on a youtube tutorial series. Keep up the good work. You explained really well and thanks. Gonna watch all these tutorials now.
Awesome. I'm learning from scratch. Already watched the first series and I really enjoyed it.
Trust me, you don't talk to a wall. Thank you SO much for your good work.
(from Montreal, Quebec).
your right he's talking to a camra
You are not talking to the wall. You are talking to a group of experimenters who are learning more from your videos than we learned in school. Thank You for your dedication.
its now 7-12-2023 and I am listening to all of the videos all the way through and practicing along with you. I am also writing the lessons down to later teach to my sons. Thank you Paul for all of the hard work you have put into these lessons.
Wonderful!
You are a great teacher ! Specially because your not just teaching us like : 'do this and do that'. Your explanation of how things work and why it does do are the key value, at least for me. Thank you ! Greetings from Serbia !
Thank you, Paul. You are the best teacher I have ever had in this life. You do not just give us the answer but you actually tell us why it is the answer and push us to Think critically and logically. I have learned many thing with you, and you actually gave me the confidence that I can do it too. Thank you from the bottom of my heart.
Thank you for the kind words of encouragement.
My LED kept getting brighter and brighter unto the perfect day😂. You're a great teacher. Three years and you're still not talking to a wall.
Wow, thank you!
Some feedback.
I follow all the lessons and do the projects at the same time. So far i haven't had any problems understanding the lessons, but this time i found it a little more complicated since im not so good at maths. I'm 53yrs old so it was a while since i went to school and this lesson was very good to refresh the memory. I find the programming easy to understand and you are very good at teaching.
Even though im not so good at english i find it quite easy to understand your explanations and you talk with words that is easy to understand even for someone that dosen't speak english very often.
Thank You for your work with these videos. They are most appreciated. Regards from Sweden
I started watching this series of videos yesterday, they took me back to 1981 and my programming in Basic days on a Vic20.
I ordered an UNO kit last night via Amazon and it's already arrived. I know what I shall be doing during the next few weeks of lockdown :) Thank you for the great tutorials.
Its reminding me very much of 'C', which I learned 30 years ago and haven't used for about 25.
OMG I got a TI99 in 1982, a Vic20 in 1983, and a C64 in 1985. Never spent much time trying to program. Played games mostly! Remember the Mattel Electronics Aquarius computer? The Timex-Sinclair that had little chicklet keys, and only had black and white display capabilities? Ah, the 80s.
@@DeeGeeDeFi I went down the VIC20 followed by C64. I spent hours typing in Basic code from magazines, more hours debugging it all only to get a ball to bounce up and down. I learnt an awful lot about code ( and about my patient wife)
The richer kids got the C64. We got the V20. It was a real treat to hood up the the phone and upload and download new programs. You hoped that it wasn't a long distance call!
I always wanted to use my GREEN LED. Thanks Paul!
for those stuck with HIGH/LOW (on or off) outputs, make sure you use an analog output (pins with a tilde), stumped me for a bit until i remembered Paul mentioned something about it (i watch the video to the end before attempting the project on my own).
Paul - I love the series. I'm an "old" guy who started learning about electronics many, many years ago as a hobby while a college senior. I took an elective course in electronics and had a lot of fun. No Arduino kits back then and I couldn't use a breadboard for testing without soldering wire leads to some components due to irregular sizes. And yes, some components were "nuked" during the soldering process. Frustrating. This is a much more enjoyable experience. I appreciate the review on the line equation. Your explanation and example regarding LED output makes so much sense. I've completed all of the homework assignments.
Now, because of the COV-19 we have to stay at home, so I have a lot ot time to learn from you and I really enjoy to play with these items :)
Paul, old guy new at this loving it, and YES doing all the homework .
Found this in 2022. Watching your videos from Minnesota. I watched it all and I've been following along. Thanks for the series! :)
This is exactly why I call this app TH-cam University. I can research topics that interest me in a timeframe that works for my daily schedules. Paul, here’s a little gift for a few iced coffee’s. Your value that you bring as an education to these topics far outweigh this token but I just wanted to give a small appreciation for your clear and concise teachings. I appreciate that you reiterate certain concepts over and over to really get us into the habit of coding and learning to use the arduinos the right way. I’m watching this videos 4 years after they were made but they are exactly what I needed now that I’ve picked up this new hobby. This channel is an absolute goldmine.
Really appreciate the kind words and support. Thanks!
Haven't only watched this series, since you're a great guy and teacher wether it is i WILL watch it because it is indeed fun and great
i just got the kit about a week ago and i'm going through these lessons. a few dozen more and i should catch up to the current one.
Oh man ... don't think for a second that you're talking to a wall. I mimic every step and take every possible note. Thanks again!
You’re not talking to a wall but across time. I bought another Adruino and the the tutorials were so bad I looked for help and found it with you. Bought the most complete starter kit and am so happy I did. Thank you
"Hook a brother" lmao every time it makes me laugh. Legendary teacher!
I love video
I’m playing along. And doing the home work.
100% Not talking to a wall! I absolutely loving this series of lessons! I follow along with every lesson and take notes throughout. I'll be real, when I got to the first lesson about potentiometers I thought I was all smart and tried hooking up a red led to the output pin... Yeah learned a lesson there haha! Did it twice just to be sure. Glad I made it to this lesson, this really clicked a few puzzle piece in place and I understand better why my early attempt failed and how most electronics actually work. I really appreciate the slow approach to painting the beautiful landscape of micro electronic engineering!! As some others have said, you're like the Bob Ross of electronics!
I didn't know anything about Arduino and also programming until 4 days ago, and now with the help of your wonderful tutorials, I am getting better every day.
I don't think anyone can teach this better than you.
Welcome aboard!
As always, good job on the math connection to reality.
Flowed along just well. I like the live mistakes, teaches me more then just do this and that's that. With the mistakes it really shows why it has to be done certain ways.
I do the Homework and also try to throw something more at it sometimes. This time I added second Pot that delayed(pulsed). Used the formula to put the pulse range to my desire, settled with delayvalue= (75./1023.)*potval2 making 5v aka 255=100ms
While first Pot dimmed dimmed them.
I'm 72 and did a little programming in my late teens early 20's. The language has changed principles of programming exactly the same. Well done for clarity of explanation. Have also completed your homework
Paul, I can assure you are not talking to a wall. I recently bought an Ardurio kit for my grand son and while we were working together with it, I bought one for myself! Why should he have all the fun?. :) I stumbled onto your tutorial videos and currently am working through them. I have finished 14 of them so far and plan to go through all of them. You have done an exemplary job in demonstrating how to setup circuits and describe how to program. I worked as a tech instructor ~40 years ago using HeathKit trainers and 6800 processors. This is probably much better than what we did with those back then. Thank you for providing this content on TH-cam. It is a blessing.
Excellent!
This is the only non-mandatory homework that I participate in
"Today you are going to be allowed to use a green LED"
Previously, on new and Improved Arduino Tutorial: "for assignment: use green and yellow LED"
He's just assuming noone did their homework. (we did)
Yup thats true
I watch these multiple videos and then bfr going to sleep to honor the efforts and the man I try them all.
you saw salvation if i am right
I’m a rebel, I used 4 different colours for the binary counter.
@@markharrisllb I am also an edgy rebel, I didnt have yellow LED's so I used red green and blue. I know I know, I like to watch the world burn!
I am here and learning, at 73 I am starting over with a train layout and will be using Arduino to control functions on the layout: turnouts, signals, lighting, and later sound effects. Thanks for these lessons, I am learning many things. Last programming I did was FORTRAN.
NOT TALKING TO WALLS ..
I LOVE YOUR WAY OF TEACHING
YOU ARE SOOOOOO GREAT
I CANNOT STOP WATCHING YOUR LESSONS..
💚💚💚
I'm 11 but I feel like I have the knowledge of an adult
Same
I like this lesson. It made me think through the steps and the reasoning behind entering the commands instead of just coping you. I would pause, think it out, then see how I did. It's all coming together! I'm spending my first hour at work doing a lesson, with a project in mind as the end goal. I haven't felt this engaged in years. Thanks a bunch Paul.
Excellent!
My son just finished taking this lesson, he now understands one application of the equation of a line and slip of a line.
Thank you 🙏🏻
Talking to the wall ? NO sir, I am watching you second by second with my ATmega, and doing everything you teach. Thank you from Israel.
No sir, you are not talking to a wall.
We actually do follow along and it is so much fun when I am able to do this project on my own.
All thanks to you.
I hope everyone gets a teacher like you to guide them with whatever they are trying to learn.
So nice of you
Paul, I appreciate your down-to-earth method of teaching. I am 78 and a retired manufacturing engineer. I worked with PLCs, but I love learning the Arduino. I am working on a program and schematic for a PID temperature controller for a pressure fryer with adjustable setpoint and LCD display, working from a K thermocouple and Max6675. My problem at this time is trying to trigger two SSRs with a PCM output from the Arduino. Thanks again.
Definitely, not talking to a wall. Your lessons are amazing. Doing homework helps to retain the concepts. Thank you for adding the math. I included the math in the code as comments, so I can remember when it all came from when I see the program months later. Keep the excellent work.
Hi Paul! I am an undergraduate student pursuing a Ph.D. degree in biomedical engineering and your videos have helped me a ton! I follow along with my own kit and really enjoy your lessons. They have taught me a lot! Thanks for being awesome and enjoy your coffee (no sugar)!
Thank you for your kind words. Best of luck in your education and career.
Paul, I am enjoying working through each of these tutorials and the extra assignments. I have been adding comments in the code to self-document as I was taught in Computer Science classes beginning in 1972 into the early 80's and saving each sketch, numbered according to each tutorial's number.
klrwhizkid I am doing the same with the documenting and saving. Also using commenting to keep older versions with the newer version on the same sketch when there is a change to the code.
Loving the lessons thanks Paul. With 305,000+ subscribers...I can GUARANTEE you are NOT talking to a wall....lol.
Just wanted to add that the last two lessons (13 & 14) the potentiometer doesn't sit that well in the Elegoo breadboard (even after changing positions and 'mashing' it in). So most times you will have to stabilise the pot with one hand whilst turning the pot with the other.
It's like the breadboard works much better with patching leads wire and LED pins, than it does with pot and resistor pins (how many bent resistor pins have you got trying to force it in the breadboard?! Yes - even using needle-nose pliers to put the resistor legs in!).
Learnt so much over the last 14 lessons. Keep up the great work Paul.
Always watch from the beginning to the end without even skipping. You are the greatest teacher i ever had. Thank you sir
I'm 16, from the UK and a friend recommended me to watch your vids. Now I'm hooked!
recently unemployed i bought an arduino kit to tinker with in the meantime. i watch every video to completion and am aghast at how clear these these explanations are, so thanks again!
Excellent!
i actually studied computer engineering 30 years ago but never practiced it. your series are simply awesome, good refresher, at least for me.
I was developing software for the DOD (USAF) in 1961 and have been in various Information System Engineering and Management positions ever since, at least until my retirement a few year ago. I'm an octogenarian with a physics and math education, so it is the Arduino I'm learning here. Appreciate your efforts, even if a few things seem old hat - heck I'm probably considered old hat. Thanks.
4 years late but really enjoying your tutorials. Tthank you.
I listen to every word and do everything you do on the screen. It's tedious at times but I like the careful way that catches all the problems. Great teaching style.
We are un 2022 , new set of Arduino tutorials ? You are an amazing teacher
Paul, you are talking to me, not a wall, terrific presentation, learning a lot, making notes and saving sketch pgms...Keep up the great work!!
Yes someone is listening and yes someone is following along. I have a Dr. Duino kit from a HAM radio friend. Thank you.
Thank you Paul, I have been watching your tutorials for years, after a break I went back to study them once again as people always go back to reading their favorite books. I always enjoy your tutorials and find them very, very useful for my work. Thank you once again for sharing your knowledge with us.
Excellent
These lectures are so helpful. I do the homework, follow along. I'm a 20 year old nuclear engineering student at MIT and I'm trying to learn programming and Arduino. This is like baby's first electrical engineering and I love it. Thank you!
No, you're definitely NOT talking to a wall but with lots and lots of us over here. These tutorials are actually exceptionally instructional and very well-conceived.
I honestly wish you were my lecturer in college, when you teach something it makes so much sense. Keep up the great work.
Wow, thanks!
Yes, I am playing along at home and having a great time. Two weeks ago I didn't know anything about Arduino. Now I can write programs and make projects.
Thanks very much for your time and effort.
Dear Paul.... I am elect.eng (75 years old) with 40 years in South Africa, and that is the first time a lecture touch my hearth. I try before many lecturers , but the way you produce the modules is fantastic. Your english (I come from Argentina) is excellent and you talk slowly and clear. I am drinking ice coffe all day!!!!... I follow you to the end!!!!... Buena Suerte!!!. Jorge in Mandeland (land of Nelson Mandela)
Your videos are very helpfull and remind me of the my technical school 45 years ago. The kit is a usefull help for creating these circuits and code, keep on the good work!
Greetings from the Netherlands ...
thank you so much Paul. I am really enjoying you videos and yes i do watch them all the way through and also build
every project with you . Keep up this most excellent series I'm 63 and loving it
I listen to the whole video. I code along in real time and I do the homework before moving on to the next video. So rest assured you're not just talking to a wall! All your knowledge is being absorbed and I am immensely thankful for the time you take and the high level of production. 😸
Now that you are drinking black coffee, it seems you are binge watching the videos. Wasnt it just earlier you were on lesson 12? Also, I certainly hope you are holding your breath while you compile your code.
Mr. McWhortor, I wrote a program of my own to dim three led's that I am using on my temperature/humidly meter, using the DHT-11. As I rotated the pot, it would reach full brightness and the go out and then as I continued to turn the pot, it would keep doing this. I couldn't figure out why. I opened the serial Monitor and saw that I was writing from 0 to 1023, just as you said not to do! I forgot to find the slope of the line and write the equation! Man, you are good. I spent a lot of time trying to figure this out then, I remembered your lesson 14 and, boom! The circuit is working. All I have to do now is incorporate it into my program for my temp/humidity meter. I did work it out myself but, I admit I didn't remember how to write the equation into the Arduino sketch. Thanks sir for all your lessons. I'm a bit slow at 76 years young but, I eventually get it! Ha ha!
I’m watching and working through every lesson. Spending a lot of time around the house these days so this has definitely helped.
I am just on a marathon to learn Arduino.. And I began last night. I felt so satisfied with my first project. Many thanks for your help, sir!
You are not talking to a wall professor! Seriously, this is the best series/book/university course Ive come across in 20 years as an engineer. I cant thank you enough.
My name is Welvaert Eddy from Belgium.
The lessons are very educational and clearly explained.
Also afterwards for the assignments to do with great success if I say so myself. One thing don't constantly tinker with your Arduino to see if it is straight, usually it is straight.
This project was so easy to do and a great refresh on linear equations, thanks again Paul. You are a rare breed that can produce a full length video without re-takes, also good to see when things don't go right, you solve on screen.
One of the things I enjoy the most, is Paul gets excited at the exact same time as I do when something works. I think no matter the complexity, when you are making something and it finally works as intended, that is one of the best feelings.
I have not come across such detailed and hands on tuition, am ripening day by day, Regards from Nairobi
What a great way to spend my Summer! Usually, I am not that motivated to watch series’s, but these videos are hooking me. Have done all the hw’s so far. Thank you Mr. McWhorter.
Have fun!
I'm following you and learning a lot. Thanks Mr. Paul! I am very happy with the style and the speed of your lessons!
I'm 59 years old and when you said linear equation I was going to quit too...but I agree with Suhaan, you explain well, I continue to learn! Thank you.
