As a retired technology teacher, I am in awe of your ability to make progressive changes in your presentation, while making everything completely understandable. You have a special gift.

I have been a professional software engineer for 30+ years and I have done lots of Arduino programming as well. I watched your video because I am very interested in motor control. The way that you teach is just universally enjoyable and very well structured. Thanks Rachel!

Hello​@@RachelDeBarrosLive

I am a retired Industrial Engineer. I have programmed PLC Controls for decades. I have good learning/Comprehension skills. I've been trying to learn C++ basics and concepts and keep running into "how to" videos from people who have no ability to Teach. Rachel is the first of MANY to break things down and cover EVERYTHING. You write on the screen and explain what "it does" and "why we do this" .......with others, I keep finding myself going out on the Web to find definitions and explanations for terminology and concepts they ignore....so frustrating. Thank you Rachel.

She really makes it fun to learn and putting everything together practically 👏and explaining step by step.

Finally, Someone who talks 'How to do' rather than 'Just a do this' You have opened a few doors previously locked to me.

No doors were opened and youre annoying.

So much fun, I'm a coder and to listen how you explain complex stuff like variable types, program and pulse width modulation that clearly and quickly explains it is refreshing! Keep up the good work!

You explain everything in such a fantastic way. I have been struggling so much with coding because everyone only talks about doing it but you explain it with examples while doing it. Thank you!!!

All I can say is that I wish I had you teaching my first collage course Very interesting and easy to follow. Many or the tutorials on KZread leave so much out of the expiation You are teaching properly.

I like the way you speak in a language most of us can understand. Too many people use the very technical language just assuming we all speak electronics and computer code. Nice job.

Excellent explanation for dummies. You explain like a teacher, very understandable, good job. I am an electronics engineer, I was a teacher a few years before I was retired, I like your style, keep it up.

I could just never get it when it came to programing the Arduino, until now. Thanks a lot for the easy and intuitive teaching style you have that really helped me understand what was going on. Most other people just expect that you already know what your doing. I cant wait to get onto some projects now thanks heaps.

Best Arduino demo I've seen so far. Thanks for the information, great teaching technique.

Wow, been trying to learn Arduino for many years by reading books and watching tutorials. She does such a fantastic job of using analogies and simple terms while starting from the simple and gradually move to the more complex. I finally get the big picture after just watching this ONE video! What a fantastic teacher….thanks for the video!

My mind is completely blown at how easy you make this look! Thank you for your videos.

Hope it helps for your next motorized project!

I randomly came across this video by following the "KZread rabbit hole." I have absolutely zero experience with the Arduino- I've never even seen one in person. I only know of their existence because some people make projects with them in amateur radio (my main hobby). Plus, I'm in my early 50s, so I don't soak up information as well as younger people. However, there wasn't a single thing you presented in this video that I didn't fully understand. Your teaching style is outstanding and you made all the gears click in my brain- and some of those gears are pretty rusty! That's a subscribe for me!

Have been using Arduinos for over a decade now and it's great to see someone who is equally excited about them.

🤣 Arduino has allowed me to do so many cool projects!

Fabulous video. SO MUCH better than books. Your production background shows in the presentation. Much appreciated. I'm just starting to learn Arduino and how to control the pesky motors. The video is a great tutorial. I'll be coming back to this as a refresher. Subscribed.

First, great video and explanation! Let me give a few remarks on coding: 1. as another commentator already stated, using #define constants instead of variables for "never changing" or "magic number" values, like pin associations, or the motor's low speed (magic number 70), is better. 2. inherited from C++ (Arduino language is basically a superset of C++), you can use the shortcut var += increment instead of var = var + increment. Works with all arithmetic operators (-=, *=, /=,...). 3. try to avoid delay(). The processor is literally delaying then, means it does nothing else. You'll get in trouble if you want to do something concurrently then. 4. I'd have the movement of the motor put into a function, like void turn( int direction, int speed ), so you reduce three lines of code into one. Same with stop(). Re my point 3: I've almost nobody seen to address this, albeit this is basic microprocessor programming knowledge I learned almost 40 years ago 😊(Yes I'm an Old White Man, and credits to Professor Reichert of Engineering school Aalen who was a great teacher). I wrote a tiny class that works as a timer and executes code after a specified delay or in specified intervals, or tells you if a delay is over instead of halting the program. Also you can break the granularity down from milliseconds to microseconds, because you can use the micros() function instead of the millis(). The caveat is that this method adds some imponderability to the programs, so you can't predict when exactly which function is executed, because that depends on if some function is busy longer than the time checking interval is. But great explanation of the Arduino's power capabilities! Overloading ports is one reason why newbies fry their Arduinos and then end up frustrated.

Thank You so much Ms. Rachel!! It was worth spending 45min here.

Best arduino Video i have ever seen. I myself attached Joystick to uno R3 , L298n, two yellow motors. Next will be wlan, maybe esp32. Started 3 weeks ago. Thank you so much.

I feel like Neo in The Matrix when he gets plugged in and learns jujitsu. Thank you so much for this. I have been wanting to add motion to my metal sculptures for years. ❤️

This is a fantastic approach to introducing motor controllers, power requirements and coding to folks 👍

I am so glad I came across your channel. I really appreciate your clear and concise instructions and explanations. Subscribed.

I just stumbled upon your channel and even though I don’t know if I’ll ever need this information I liked and subscribed. You’re simply a great teacher and I need those in my life!

Fantastic video! I am an industrial automation programmer (PLC Ladder logic mainly) and have recently been getting into Arduino and Python. Your video is very informative and great to follow. Especially for a novice Arduino user like me. Thank you for your contributions to the community!

I have always been drawn way more to hardware then programming, but this integrates both. The industrial machines i worked on do this on a larger scale, so this is the path to greater machinery starting here.

Awesome video, Im a sophomore Mechanical Engineering student and this video really saved my project.

Hi, Since years I wanted to start with arduino to drive a small wood prototype and your video is so clear and well explained and your positivity makes the video very enjoyable thank you very much !!

I'm taking up Arduino programming because of you. You simplify the jargon.

This is absolutely fantastic info! Where have you been all of my electronics life?! I have done so much research and experimenting with so many motors and controllers over the years for various projects and have always been stuck with using stepper motors which I thought were the only way to achieve some kind of accurate control. As you may know stepper motors are quite limited in variety, (especially when it comes to smaller sizes), and these are also relatively 'under powered' for many applications. This type of control opens up a whole world of possibilities. Thank you so very much for your time and effort. Awesome video.

Just finished watching. great stuff. I know a a lot of people who are going to be your fans. thanks

These videos are just brilliant... Understanding electronics is one level but comprehending it like your videos is another!!!

Just built this and could not have done it without your excellent video!

Awesome! What project are you building with a motor?

Hey! Just discovered your video and am falling in love with you already. You're such a great teacher. Wish I could say the same for my teacher. He sucks!!!! You're sooooooo clear and precise. Guess I'll be coming back for more.

I love how arduino has opened up this kind of work to people without formal technical backgrounds. For a lot of things, if someone can make a spreadsheet, they can use common sense and online examples to do what they need. I love watching your stuff, since you embody that ethos perfectly. Keep it up, and good luck to creative people adding tech to their creations!

Rachel, you are a gem. Explanation is simple.

I’m so happy I found you. I’m just starting to watch your videos, but just in one video I learned a lot. My brain almost exploded just like my motor controllers have 😂

I wish i found this video when i started learning arduino, sensors, and controlers. Great work.

Everybody else on here has already stated it so i wont, oh hell yes i will, absolutely brilliant video/tutorial, the best i have ever seen on coding, thank you

If everyone had this attitude we would have warp drive by now...your awesome thank you for all your effort.

Brilliant. No reason you came to my feed that I know of. But so good that I have this for reference now. Really enjoyed your voluptuous style and clarity as bright as your eyes. If that made sense to anyone you have a better grasp of english than I do of Arduino! After Rachel De barros explained and demonstrated how to make it function for "You"!

Thanks for this fantastic video! It's exactly what I've been wanting to do and you really made it clear and fun. I'm totally new to all this and this all makes clear sense.

Keep me posted on your project and let me know if you'd like me to cover any other topics!

I find your video very useful. Help me a lot to follow. I'm a newbie here and have troble catching up with other videos. I have to pause to find another resource to explain in details and come back to continue. But your video is totally different. Well explained in the video itself. This is amazing! Great stuff. Thank you so much and subscribed!

Thank you super video. Have an arduino for nearly 10 years with post purchase blues. So didn’t get much done with it. Thank you you have energised my imagination hopefully I get a project done now

This looks like so much fun. You're using 12v automotive components, 110v power supply and that little red board is doing all the work. Nice.

This is perfect! I plan on using one of these motors for my gate openers and this is the last part I need to install it.

RACHEL !!! I am so glad I stumbled across your channel. Weird timing: I am teaching myself Arduino programming to control servo motors for some machining projects I'm trying out. Awesome job explaining what you're doing, and how the Arduino works! That helps me learn as a newbie at this stuff. I so miss seeing you on All Girls Garage! Subscribed now, so I can start getting my "Rachel" fix again !

Just found you, and you make it look easy, you are a good teacher, I been hearing this Arduino but kinda intimated, but seeing your video, I feel I can do a simple Arduino project, thanks a lot.😊

You teach very well and your personality makes the videos very easy and fun to watch.

I like the Drok motor controller. That's what I use. It uses FET's, and it doesn't have a heatsink, and from what I've experienced, it doesn't hardly get warm, even with heavy use. I think it has opto-isolation, and that's one reason why it has a separate ground. It seems to be a pretty trouble free controller. Also, the wire receptacles are removable. This makes it very easy to wire, if the board is already mounted in something. You can attach the wires to the receptacle, then plug it back in to the board. It also makes it easy to switch channels, if you want to test the other channel. The power input receptacle is also removable too. If some accident happens to your board, you can easily swap it out, and the project remains wired - aside from the control wires. I like that there are lights for both the control section, and the drive section, so you can tell which sections have power. Also, the positive and negative pins, for the control section are joined, so you can daisy chain & power another board, with the free pins.

I was a controls engineer for 45+ years and also taught industrial controls and PLC's at the local community college. You have a very nice teaching style, good job. I just found your channel so what I'm about to say you might have already addressed in another video, but when using Arduino, I tell people to never use the delay() function because the delay() function literally stops the program from executing code. So...if you set a delay(3000) 3-seconds and there is code below the delay(3000) that needs to be serviced during that 3-sec. delay, it will not get serviced. I recommend using the millis() or micros() function and setting a duty cycle with a bit of math for current time and previous time. That way the program keeps "scanning' the loop() function even during the delay.

You're absolutely right! 👍 Except for simple programs, I usually stick with millis(). I do have a video dedicated to using millis and another one for using interrupts. But I can't deny that delay is an easy concept for beginners that have little to no coding experience to understand, so that's why you see them in all my beginner videos like this one. I have another millis video coming out using a PIR sensor to orchestrate LEDs, servos, motors and mp3 players in March! Stay tuned!

@@RachelDeBarrosLive Thanks for the reply Rachel. I found your millis() video and your interrupt video. Very well done. I'll be very interested in the mp3 player. I'm doing the research for animating a Moebius 1:6 scale Lost in Space robot and already have sound files so I'll be interested in how [you] do the mp3 player. I'm looking for one that I can chose what sound track I want to play. My plan is to have everything RC controlled. That's all new ground for me, but it's so much fun!!!! I'll be watching. Great job!!! I'm so glad I found your channel. 😀😀

That was really fun to look. Good job. Vary clear explanation to understand in detail.

Excellent true explanation of the workings between the motor to arduino. Spot on!

I love your accent. I need to get back to my arduino and raspberry pie projects. Thanks for the motivation.

You have a great way of putting the information over I'm new to coding.

You explain it simple. Make it easy to understand.

Beautiful! Finally explaining it all! Thank you!

Hi-eee. Newbie to Arduino (obviously why I'm here) your channel. Was watching on my own, then my 8-year-old came to see why I was chuckling. She sat on the floor and I wanted to if she grasped any of this or was even interested. So she watched you because I was laughing at how you make some expressions to get the point across. A child being a child, she watched for the 1st.15 min, 12 minutes longer than I expected. So I think I'll show her more of your video in small doses. You know Baby steps. It's how we learn.

Thank you for providing such a great video, you were a pleasure to watch and so very good at teaching!

Outstanding tutorial. Turning that motor on or off with a button or sensor would be a dream come true for me.

Great idea for a future workshop! In the meantime, I have an upcoming one about how to control a motor with a motion sensor later this month.

I've been learning C script for making video games inside of vrchat and I recently decided to start learning about programming Arduino boards I can't believe it's all the same kind of code! Thank you for this!

Great pedagogy Rachel! Thank you! You earn a new sub!

Hi Rachel and thanks for a great video 🫡 I really like how your explained all the functions of the arduino so now i feel like starting to use mine that's been in my drawer for 5years 😂 Keep up the good work and you've got yourself a new subscriber from Sweden 👍😁

absolute amazing video!

Its fun listening to you and you're telling it as a story, and my brain thinks "oh, now its actually easy to understand". Thanks for this!

Great video with superb step by step explanation. I am new to coding with arduino and have a complicted machine to program. This has help no end to help understand the environment , instruction set and the logic too. Huge thanks for doing these vidoes.

that was the best explanation of code on the arduino ive seen.

Great video+explanation+presentation! Thank you for sharing well done mate - NEW SUB 🙏🏻

I'm in love, Glad I found this channel..

Love the way you describe it in my language not all scientifical. And your HOTT!

2:57 - you're definitely not the only one! (I'm embarrassed to even say how long ago some of my not-yet-completed, but-still-being-worked-on projects got their first starts...... 😲) Nice tutorial!

Just sub's I have been interested in this for a long time just never found anything that at least explains it and was very helpful, you instructions made this really doable for the newbie. Great video

Great tutorial, Especially as i was looking to build my own motion sensor for a sim racing rig using Simhub, Subscribed!!!!

Love your style of teaching, well done.❤

i sat and watched your video last night in bed and though this video is gunna be a right bag of u know what, but bugger me turned out really good i actually learned summet that is going 2 be bloody usefull to me so big thumbs up and iv subscribed

Like your. passion and simplicity explanation, with visualization of real working materials ,that represented, very good!!!

Thank you for a clear explanation of pwm motor control.

Great job very informative for a old man like me, thanks.

Basically this would be a good video if you show how to control the wiper motor at delay various speeds between low and high and then you have the shut-off circuits that make sure the wiper blades shut off and the blades are in the right position. This should be super great video with just with simple things like this, especially the time delay on an older wiper motor.

Great tutorial - thank you for this!

Great job. Thank you so much.

Good job, well done. Explained very well.
