#Arduino - Věda a technologie
Nearly 40 videos in and I haven't *really* said thank you yet, so here's my thank you! You deserve a lot more than this, sir!
WOW! Thanks, really appreciate that. It is a real encouragement.
For anyone that was ever wondering, this is actually why fans, like box fans, oscillating fans, etc, have high as the first speed on the dial. It's to kickstart the motor 🙂
interesting
Interesting for sure
dang man, so cool
Thanks 👍 that makes sense 🙂
Thank you for taking the time to give us this information.
Rose and Ronald. Great tutorials! Everything pedagogically and clearly explained, packaged and delivered in a professional manner. Some things have obviously happened on the electronics front since I studied to become a merchant marine engineer in the 80's. Now I have a lot of catching up to do as it seems ;) Thanks a lot for your tutorials, time and effort!!
I know I'm 3 years late, but this series is as awesome as roses!
Same, but his lessons still hold up.
Why does internet teach me better than the school I'm forced to go so I can find myself a future?
This sir has taught me in under 1h everything I've been trying to learn in a whole week at school
Thanks a lot!
Sir , these lessons are top notch nothing on the internet beats your Arduino content. Excited about your upcoming premieres.
Merry Christmas Paul, Rose and Ronald!
I’ve been watching your Arduino tutorial series from lesson 1 and have been able to follow along up until this lesson, always doing the assignments before watching the video and have been able to successfully do the math and all without much problem. That is because of your most excellent teaching of course. I’ve learned so much since I started watching your Arduino tutorials about a month ago. I literally didn’t even know something like the Arduino existed till the beginning of this year when I started watching videos from Mark Rober, the Hacksmith and Colin Furze and discovered the world of engineering, electronics, machines like 3D Printers and CNCs and CAD. I was blown away and fascinated at the machines and at what these guys were able to design and build and was always hearing them say they used an Arduino for certain parts of the build.
It was until 2 months ago that I finally decided that I wanted to learn how to use the Arduino so I bought it but was overwhelmed and did not know where to begin since i basically knew zero about electronics or programing and the tutorials I watched kind of assumed the person already knew a bit of what they were talking about and so I was beginning to feel a bit discouraged until I found your Arduino tutorial series and with your most excellent way of teaching I began to understand how the Arduino worked.
Your videos and your teaching is amazing because i have not only learned how to build circuits, how to write code and how to troubleshoot but i have also learned Math and Physics and how some components work at a fundamental level.
I am very grateful to you for making these amazing lessons and making them for free and I am very excited to continue learning. I am also planning on watching your Fusion 360 Tutorial Series because I also want to learn CAD and how to 3D Print.
Also for this lesson’s assignment, I decided to challenge myself and see how much I’ve really learned from previous lessons and did the assignment but I tried to incorporate every component we have learned to use so far. I hooked everything up, wrote the code from zero using everything I’ve learned so far and once I uploaded the code and saw everything worked perfectly and exactly as the code was written and based on the math, i was blown away. It was a very rewarding feeling. I was smiling the whole time!
I uploaded the video on my channel and put the code in the description if you would like to see it and maybe grade me on my progress so far XD.
Again, thank you so much for making these amazing lessons and I am pumped to see what we will be learning next.
Merry Christmas!
ever since I got an Arduino I also watched different tutorials on Arduino but after I come across your channel I found all the needed fundamentals on Arduino and I just love your content been 3years since released and still doing wonders
I have run through all 37 lessons and they all work fine. I do listen to the whole lesson. Rose & Ronald
I KEEP WATCHING; GREAT TEACHING; WE NEED MORE TEACHERS LIKE YOU:
yes
@@theminecraftdabberpros3409 you are 100% correct
same
Thanks Paul. I've learned a great deal from your videos. Better series than 30 days lost in Space and much more pleasant to watch!
WOW, Really appreciate that. It means a lot to me, thanks!
@@paulmcwhorter secret code is rose
This was a great tutorial because I actually had a problem with it! Teaching this subject and having studied it in school means that I have a good understanding of the subject matter. However, I couldn't get it to work, so I had to debug it. Using your method of debugging, I went through the possible problems. It turned out to be a faulty wire. I decided to create a project for my students in which there would be a problematic component (a bad wire which would be given to my students without them knowing it) and my students would have to figure out why their circuit wasn't working. I am co-teaching a electronics lab class at a local university next year and was asked to do so because too many students are now too heavily invested in theory rather than practice (building the circuits they design), so they don't have a real world understanding of the many things that can go wrong. Another great video!
I’ve watched every single episode of the new and the old arduino tutorial series, from start to finish, keep up the great videos Paul, Rose and Ronald 👌🏻
me too
@@zainmehmood4808 Were you a beginner in programming, and did this method of learning with Arduino help.
Rose and Ronald in the Garden.!!!
I always follow your video's to the end.
I THINK I CAN GIVE YOU A PARTIAL EXPLANATION OF THE AVERAGE SHORT VIEUW_TIMES:
Many times, i see your videos a second or a third time or more.Most i lookup just little fragments , that i did not understand very well the firtst time,
Sometimes i scroll back or forward to see better some details, to write down some parts of the sketch...or understand things better....
I do that because i am just a beginner, and becoming a litle older and slower (66 y).
I think more people do that.If every short revieuw is counted as a vieuw.....this could make a big number of very short vieuws.
OF course there will be a lot of experienced an clever young arduino-users, and they wil also be curiuos what yo say... but as they know already everything
about arduino and much more, they look and say :"yes i understand this all what he is saying.... and stop the vieuw.
Yes, I too watch the videos all the way through and then go back several times to review specific items to make notes for later. Usually, I will re-watch part of the last video I watched the day before to refresh memory and then move onto the next video Tutorial.
I actually enjoy the CZcams ads and found some great deals because of ads for items I never would have know about without the suggestions.
Same here on your comments, beginner status and age range. I too like to go back and forth for all the same reasons. This is a great resource and when completed I hope Paul considers puling it all together with supporting resources for us to buy
true
Yep, I like to go back after performing the exercises to get my Virtual Breadboard updated to go along in the folder with my saved sketch. And maybe a skim through to add bits to my notes.
I do this too.
I always watch until the end. Thanks to Rose and Ronald for keeping the yard nice and tidy!
Rose. Great Tutorial. I started going through this tutorial 3 days ago and I followed each lesson beginning to end (including homework). I am so glad you pulled this series together Paul. Well done!!!
Rose and Ronald :) Thank you so much for making these videos, they're super helpful and very much appreciated! I'm a university student studying Computer Science and one of our classes is all about embedded systems. We cover a lot of material in class and usually if I'm struggling on something in particular, I come along to your channel because you explain things so well. It's great that you're easy to understand/follow and I also like how you repeat key concepts, making it easier for us to remember.
Your videos have been especially important during the 2020 Coronavirus quarantine period, since us students haven't been able to attend classes - These videos have been a real saving grace for us, and I cannot thank you enough for taking the time to record and upload these videos. God bless you.
Ronald and Rose. Thank you for a brilliant series of tutorials. I suspect I would not be the only one to say how much you are helping me to get through this lockdown ! Thanks again.
Rose and Ronald look like great folks! I'm 57 and brand new to this world of circuitry. This is becoming a hobby that I can carry into retirement. The way you teach is so helpful! Thank You!
Welcome aboard!
Rose And Ronald, Love your videos dont know what id do without you. Thanks!
"Rose&Ronald" gave us this great series of arduino. Best series I have watched so far.
Rose and Ronald
Thank you for the amazing content
Rose and Ronald.. typing with one hand only, other one is actually holding my mug of iced coffee
👍👍👍
You had us in the first half, not gonna lie.😂😂😂
Rose and Ronald!. Another great lesson, thank you. Even 4 years later.
Came back for a review of the content. Learned a lot, again!
Please support Mr.McWhorter! We need him. The world needs him. Think of all the good he has done and will continue to do. Think of all those he has impacted and will continue to impact through these classes.
I've watched all of your tutorials to the end so far. I've even some of them 2 or 3 times by way of reminders.
Rose & Ronald is what you requested.
In india the cost of elego kit is more than 150 dollars , nearly my father's income per month
But I feel happy that at least this courses are free , thank you MR. Paul from bottom of my heart
"Rose and Ronald"
Rose and Ronald look like they have a great life.
Managed the homework by removing the low speed running / boost on startup so all delays were removed from the void loop.
Most sincere thanks for the great lessons.
Rose and Ronald.
Hope they are doing well and still taking care of your yard.
Excellent lesson, thank you 🙏🏻
Rose and Ronald. Excellent video, as always. You know, Paul, this is probably a minority opinion, but I'd really love it if you'd do another series of Arduino videos, but with more "behind the curtain" explanation of how the magic behind the sensors, components and ICs work, similar to your explanation of semiconductors and diodes in #2. I found that super helpful. I realize that this potential series wouldn't be as popular as some of your others, but I'm pretty sure there are quite a few of us (who tend to be silent) that would watch, learn from and appreciate them.
"Rose and Ronald"... Thanks for this very interesting tutorial!
Man I love your stuff! Despite being a complete noob at all this Arduino stuff I was still able to successfully control a simple DC Motor with my arudino in the very first attempt! My heart goes out to you! Thank you so so much for this beautiful, simple and highly instructive video. God Bless You Sir !
3 years later..... the rose s are still blooming. Thx for your videos and input. greetings from GER
I've watched till the end... love the yard rose and Ron...
“Rose and Ronald”. Thank you very much for the great lesson and channel.
Had to slow down over the last couple of days. My L293D chip was bad. Learned a lot about troubleshooting and finally figured out my chip was likely bad. Ordered some more and now I am in business. Everything works. Great lesson! Rose and Ronald.
Great to hear!
How do you know your chip is bad please ?
Rose and Ronald, very nice lesson. Will continually play with this one for a few days, tilt + red led for tilt, potentiometer for speed control button for reversing...etc. Thank you!!
Rose and Ronald 😄😄
I really would like to do this project, but I have another starter kit, and unfortunately I don't have a DC motor, so I just wrote the code with you. Thank you for this lesson 😊😊
Rose and Ronald! Thanks for starting this series, playing around with Arduino has made me deeply interested in electronics engineering and coding. I have tons of gadget ideas now that I'm learning my way with electronics, and it's thanks to you! Keep it up man
Hi, if you have knowledge about it, can you please explain what is the role of the power supply? I do not see anything wired to it, and in any case the power is coming through the Arduino. Unable to understand it.
ROSE!!!! I was able to get the fan working with the tilt switch. I always watch from the start to the end because you never know when the gems of knowledge are going to pop up.
Rose and Ronald
I started on video 1 and still going strong on 37, every video start to finish and all the homework. Im having more success with the homework as time goes on, I guess that means it starting to make sense with every video. Thanks.
Well done!
Hello Sir!! I’m a Mechanical Engineer in the aerospace industry, I have “very” recently gotten into Arduino, and your videos, so far are the best ones for me. I like this one in particular because of a project I am working on. I have a 9gram, continues rotating servo, I’m trying to get it to rotate in one direction for a certain amount of time, then shut off, then when activated again have it rotate in the opposite direction for the same amount of time. Can you help?
“Rose&Ronald”.nice video and I did the homework .
Rose and Ronald. I have followed many other tutorials from other teachers on Arduino and did not learn much.
But your videos are the best and I am following each and every lessons on your Arduino channel.
Thanks a lot.
I always watch the whole video, and always watch more than once. I am a silver learner ( recently retired teacher on the England/Scotland border ). I did some programming in the 80s/90s using BASIC but computers got way to complicated for amateurs to mess with and life got in the way, as it does. So I lost the habit of coding until the arduino came along. So now I am working my way through your videos , enjoying learning a new skill. Thanks so much for posting all these . All the best for 2022, Peter.
Something really magical about BASIC. I worked in the 80's doing instrument control with HP BASIC. You could control test and measurement equipment using simple BASIC programs. Really a magical time for me.
@@paulmcwhorter I'm pleased to have reminded you of a happy time. It was surprising what you could do with just a few Kilobytes of memory.
anyone that doesnt like this channel will have to fight me
Don't forgot to plug your 9V into your power supply! Otherwise the motor won't spin. This wasn't mentioned in the video and I forgot to do it, hopefully I didn't harm anything lol
Rose & Ronald - Well I, for one, watch your excellent videos right to the end every time.
Rose and Ronald - just to say I have always followed the tutorials from start to finish.
Paul: today's secret word is "Rose."
People who made to the end of the lesson but barely missed the secret word part: ....
Rose and Ronald probably noticed the excessive baud rate of 96000. They would ask you if you meant 9600.
Rose and Ronald! The yard is looking great. I am blow away whenever you share pictures of how beautiful Africa is. Did the homework and got it working nice with the tilt switch by removing the delays and boosting the speed to 255. Thanks for all you do for us! Blessing to you and yours!
Rose and Ronald! Of cause Paul's Arduino lessons are worth 100% watching. Shorter-time watching is only for searching or refreshing specific sequences in previous lessons. Assignments are occationally difficult, but stimulating, with a success rate of 50% so far for me. Thank You for all teaching!
ROSE AND RONALD
Rose and Ronald. Before I start on the homework, I need to enter notes in my course notebook. Whether I am the instructor or the student, I have always kept notes. I am 80 years old and have many notebooks. Since 1979, with my TRS-80 for a start, these notebooks are in files. I was a graduate student at Dartmouth in 1965 when the time sharing computer first became operational. I have, to this day, kept my first BASIC programs.
On a related topic, before you can use the simulation TinkerCAD, you have to build the 5v. power supply. I will do this later.
Rose and Ronald. Some of us are still learning from these incredible lessons 2 years later. Thank you so much.
Great to hear!
Rose and Ronald! Amazing lesson :) did the homework and incoperated a green and red LED combined with the tilt switch to indicate the tilt state!
Rose and Ronald for Paul. Everything I know about Arduino, I learned from your CZcams Channel. Love it! Thank you so much.
To Rose and Ronald, this is the most fun on CZcams. I put the initial kickstart in the void setup(). I figured it would only get run once and leave the rest of the code cleaner.
ROSE AND RONALD, PAUL!!!! I can't believe that the average time is 3 minutes. I don't think that I've watched a video of yours just once, what's left to watch it just for 3 minutes. So informative content! I have no idea what most people learn for 3 minutes.
Rose and Ronald, 2022 here. it's never too late to learn something new. Thanks sir Paul McWhorter, i've been following your video since tutorial # 1
Excellent!
Rose and Ronald.
Thank you for another excellent tutorial. I have done every one of them in sequence, and to the end. BTW, my motor will run at 73, but stops at 72.
Rose and Ronald!!! This video was awesome!!! Thanks for keeping this free on youtube!!!
I started knowing nothing about programming, now I'm making robots and various other cools things with Arduinos. Thankyou.
Rose and Ronald are doing a fine job
Paul you lessons are brilliant👏
I gotta say at first I couldn't get my motor turning and tried all sorts of debugging which you've taught Paul. Found the motor started to make a beeping sound and went back through the video to realise you had a 5V battery plugged into the power supply module. Got it to work eventually. Cheers for the lesson!
Rose and Ronald cheers for video I'm a beginner with all this stuff and I'm learning slowly I want to make my own motor controllers in bulk and install as a package with ebike
This was very hepful! Thank you!! Excited to follow along with more. Beautiful yard with Rose and Ronald!
This was a great introduction for L2930 chip, Thank you. Rose and Ronald!
Rose and Ronald. Brilliant Tutorial! Thank you, Paul.
Rose and Ronald - We always go all the way through your most excellent videos! Thanks for your teaching!
Rose & Ronald. I'm new to Arduino and programming and this course is good to follow. I am able to do some parts of the projects without just copying, but still struggle to remember some of the language when programming.
Rose & Ronald I've watched every video completely up to this one and enjoyed them all. Looking forward to watching the rest of them. Thanks
Awesome, thank you!
Rose & Ronald - I did the homework and made it work - I trick I did with the tilt sensor instead of tipping the board I unplugged the ground wire to simulate the tipping
Rose and Ronald! And now off to do my homework...thanks for your time and effort, Paul!
Rose & Ronald. Very educational. I am South African and I find your way of teaching very helpful. I did not have the L293D chip, but I did the code anyway just to practice on my coding skills. Thank you.
Another winner. when I get my tilt switches in I'll complete the Home work. In the mean time I'll substitute a pushbutton switch so I can verify my code. Rose and Ronald have given me the go ahead.
I watch your videos to the end. I did the homework and also added a pot to control the speed of the motor. Great tutorials!
Cool, thanks!
I watched all of his videos until the end. They are very good and have helped me a lot. I saw Mrs. Rose in the yard. Many congratulations.
These videos are from 4 years ago but I watch them to the end. And over again.
Rose and Ronald, I always watch to the end Paul, and also pause and re-watch taking notes as I go along. Thanks again for a cracking lesson!
Rose and Roland. I did it with Texas Instruments SN754410 and it needs an additional VCC to pin 16 to get the motor started.
Thank you, Paul McWhorter, Rose and Ronald!
I have got up to Lesson 7 and find them very easy to understand and informative. I will be doing the complete course even though I'm retired you never stop learning and I thought programming and figuring out how to program to an outcome was so interesting. As a plumber your explanation tells me how a automatic devices work!
Nice work Rose & Ronald! Another awesome lesson!
For some reason I couldn't find my my L293 in my adruino kit (not an elegoo) but luckily there is an electronics supply store across from work....I call it my toy store!
Rose & Ronald. You have helped me learn such a valuable tool for so many projects!
IF your motor doesn't turn like mine - you probably havn't connected a DC supply to the PSU - the battery that came in the box was inadequate to power the motor, i found a 6v-9volt old charger in my house where i cut the end parts to expose the black and red wires, then simply removed the battery and connected the wires to the battery port (electrical taped). Be sure to check the push switch is on and your fan should run perfectly. Wish it was mentioned in the video to connect it otherwise perfect video tutorial.
Rose && Ronald.
Yes watched to the end, managed to get this one working myself. Really pleased with myself.
Rose & Ronald. I am waiting for my kit and I already watched 5 full videos at the start and a few more advanced videos for motivation.
Rose is my favorite flower. Love you, Mr McWhorter!
Ahhhh . . .
Rose and Ronald! Keeping the lawn in tip-top shape!
Rose and Ronald. My motor actually runs only at 255 and I need to twist it to start. Have ordered different motors and will try again tomorrow when they come in. Thanks for all the great videos, learning a lot.
I always enjoy your classes and I take them with great enthusiasm! Rose and Donald.
Rose and Ronald. sir, I am still with you from Bangladesh. Your tutorial is really great. it is helping me in my engineering. it's so deep and knowledgeable. I really appreciate your work on the Arduino and other projects you are working on.
Rose and Ronald!!!who wouldn't stay till the end?Thank you for the videos
Yes sir I stay till the last. Its always good to watch your videos till the last. THANKS SIR
I appreciate that
Rose and Ronald, yes i am here, I love your video's they are great i had trouble with the motor turning pulling my hair what there was anyway, but went slowly through the clip and found you switching the jumper wire on the power supply, it was hard to see but figured it out and boom it went.
Rose & Ronald. Thank you Paul, I always watch till the end.
I have watched every video in the series so far and have done every hardware project. I intend to finish the series. Thanks for taking the time to do this.
Great to hear!
I saw where at least one future session involved reversing the motor. SInce I was using a 2n2222 transistor to do this project I realized that I needed to acquire the IC. While reversing a motor with transistors is certainly doable, I'd rather not spend the time building my own H-bridge. I picked up a L293d and redid the session with the IC. Thanks for your help. It looks like I've got an issue with the homework though. My tilt circuit isn't working. We'll see what I missed in #38. Thanks again, Chief!
After watching this lesson I was able to make my own project which I've been wanting to make ever since I got this kit, I was able to work with a dc motor which was attached to a potentiometer which would in result control a servo motor. Thank you so much.
