Arduino Tutorial 17: Understanding Arduino While Loops

[@jasongreen6834]

Just to let you know...Three years on and people are still watching and learning, holding their breath when you compile, banging the arm of the chair and yelling "BOOM!" Wonderful legacy Paul.

[@iloo0oha997]

that booms was of chair?? i thought it was table

[@mertthew6332]

And that is still a fact 👍

[@syedibraheemzeeshan806]

I am watching it today almost 4 years later. Still Valid thanks a lot!

[@999kestas]

just to let you know i started after 4 years :DDDD

[@khalidaziz2196]

i thoght i'm the only one who do it realy, and yelling booom hahahaahhahaha

[@jameshyde6395]

I watch your video's Paul, you have taught me a lot, I am sure you are not just talking to the wall. Thank you.

[@robertlegg8759]

Hi Paul, Thank you. I love your videos. Keep them coming.

[@jarrellestes1793]

Older guys enjoy to.

[@sst8872]

I'm listening intensely! Thank you, Paul.

[@tanphuc2320]

im sure he get some of his students sit in front of him for 20 minutes traight

[@emilbester8771]

Paul's easy style of lecturing is very effective. His teaching logic is easy to follow and, because he sometimes make (deliberate?) mistakes, his lessons also teach program debugging at the same time. Well done, keep it up!

[@LolrSk8rXD]

BOOM!

[@mikecargill5595]

I teach at a small school in western Kansas. I believe that the future belongs to those that understand coding and electronics. With your help, I'm introducing the understanding and application of an Arduino. On behalf of myself and my students thank you so very much.

[@therzook]

and physics, mechanical engineering or any other area of science, electronics and coding is only tool in complex process, solemn understanding of these is pointless, but always advantage.

[@fluffyrobot1569]

I have learned so much thankyou so much for what you do!;

[@architchoudaha374]

I completed 1/4 of the playlist with this video. Clearly, you're one of the best instructors I've ever seen. Thank you, Paul, for this beautiful playlist.

[@TheScissorunner]

This is really getting fun!!! I expanded on this lesson by including a while loop for the counter and a third while loop with second led. Here's my serial monitor output: Testing, pot value is: 615 // reads initial value 1 // countdown to three loop 2 3 Safe zone value: 616 // reads value, turns on "safe" led Warning! over value: 1023 // turn pot up, reads value, turns off "safe" led, turns on "warning" led Warning! over value: 1023 Warning! over value: 283 // turn pot down, reads value, exits loop Resetting! // loop has been exited Testing, pot value is: 282 // returns to top of void setup 1 // countdown repeats 2 3 .....Etc.

[@tomlee47ut]

I am a 75 retire mechanical engineer trying to learning computer coding. I bought the tool kits as recommended by you in your video. I find your lecture to be very helpful and fun to follow. Thank you for your time in teaching us.

[@paulmcwhorter]

Glad to hear it!

[@joematarc5245]

I'm devouring your tutorials like there's no tomorrow, (: thanks so much.

[@marcelomarquesrangel]

Me too. But then, I coded this: int j; int delayT=500; String mes1="Today"; String mes2=" is yesterday's "; String mes3="tomorrow."; void setup(){ Serial.begin(9600); } void loop() { j=1; while(j

[@KenJacobson-v8v]

It didn't work at first; but looked back and found several silly errors like colon instead of semicolon, typed the word "High" instead of "HIGH". The IDE is really amazing how it shows you the area in the program that needs to be fixed -- very impressive. Your teaching is even more impressive - thanks Paul.

[@kadem7jj79]

NO , YOU ARE NOT TALKING TO THE WALL !!!! Really good teacher..great educational talent !... very clear video and sound quality ... I write out the sketches, on the arduino screen, and building the circuits, and try them out. I hold my breath,... there is not always a BOOM, but i i learn from my mistakes, and retry until it's really BOOMING and i UNDERSTAND what i am doing! Thanks for your HIGH QUALITY INPUT! ......Greetings from Belgium !

[@thuongtruong1288]

I am an Arduino Uno R3' s beginner. I like very much your Tutorials. Thanks a lot. Tony Truong

[@clarityautodetails5304]

Yesterday I started this series. Today I know how to do all kinds of things that seemed too complicated a week ago. Everything has been going great as I’m watching these videos, the homework assignments have been challenging and fun, and I feel like I’m getting a solid review on coding that I never realized I needed.

[@gdpower456]

i'm a retired engineer and my son introduced me to the fun of this series. Keep up the good work. I am learning more with every tutorial. best regards

[@autocrosser10]

Another great lesson Paul. After todays demonstration I added another variable so the serial print would output a 0-5V number. Then added a second LED (yellow not blue or green). The yellow LED turned on between 0 and 2V. The yellow LED would also blink from 2.0 and 2.5V. The red LED would turn on between 2.5 and 5V. Thoroughly enjoy your lessons. You sir, can teach!

[@thomashoffmann5603]

Best Arduino lectures I've found on KZbin! I love em, I love the way you teach wish I could have had you doing my engineering degree. Anyone found a advanced C++ course to take after this? I love this way of learning!

[@PriestGx]

I bought my first Arduino 10 years ago. If only I had access to your videos back then... I bought a new starter kit now and learning so much from you. Thank you so much

[@paulmcwhorter]

Glad I could help

[@simontopley4771]

Just revisited this one, yes, getting the hang of this more now.

[@Pinchington]

I love how you integrate software development along side hardware design. You make it easy to understand while showing practical applications. Thanks bud!

[@paulmcwhorter]

Great to hear!

[@Obonyogt]

Your the best lecture of Arduino much greetings from Dar Es Salaam, Tanzania welcome!!

[@320mb]

Paul, there are Many out here who are just starting to Learn Arduino including Myself. Just for My benefit I added 2 extra LED to this While(loop) if the potVal is lower than 400 a Clear LED lights, if the potVal is between 400-800 an Amber LED lights up... Red LED lights up if potVal is over 800. Your Teaching style is Fantastic and makes People want to Learn and Experiment....

[@denniswinden3895]

Paul... Thank you very much for your videos...I'm 60 years old and always wanted to learn about electronics....Bought my eelego kit and have made it this far! I was racking my brain trying to figure out why my light would come on at 1001 but wouldnt go off less than 1000.... finally saw my error....digitalWrite (potPin,LOW)....oops should have been (redPin,LOW).... I'm Learning! Thank you again!

[@kevernet]

Discovered Arduino many years ago and not being a programmer, mostly just cut and paste. Now retired and taking this from episode 1, through to the end, fantastic teacher, so thanks again.

[@BirdYoumans]

I have learned a LOT from you my friend. Thank you!! Tho I have a decent little workshop, I just found the circuits part of tinkercad. It will actually simulate these circuits using the arduino. So for those that don't have any bucks, find tinkercad and click on circuits and you can practice coding and see the results there. Free! My use for arduinos is for some projects I am making using LED's to outline things such as animals or hearts or whatever and then make them blink in artful ways. I have to use a Maga arduino for most of the projects because of the large number of LED's in the projects, but for simpler ones you can use the uno. But I can practice coding in the simulator and get proof of concept even if I don't light up 80 LED's in the simulator. You can practice for loops, while loops and all sorts of things. They only have the Uno in the simulator. Wish they had the Mega. But just thought I'd mention that.

[@chidiukoha62]

Youre students are so lucky to have you as their teacher you are truly talented thank you for the lessons

[@bernardo6119]

I just wanted to express my appreciation for your excellent teaching in electronics with Arduino. Your enthusiasm and depth of knowledge make learning engaging and inspiring. I truly value how you dive into the details, helping us understand the concepts thoroughly. Thank you for your dedication!

[@paulmcwhorter]

You're very welcome!

[@FernandoRodriguez-uo2fk]

I started to feel programming Arduino “all natural” thanks to you. Ive been using arduino for about 6 years now (every now and then), but whenever I needed to do something I just look over the internet for sketches just about what I tried to do and copy, paste, copy, paste. Some things I understood, most not. Now Im finishing a project about a C3P0 face that based on a pir sensor, turns the head, turn on the eyes, says something, looks back front, says something more, then finally shuts its eyed down fading and waits. Yesterday I wrote the sketch understanding what I needed and how to do it. Know what? I done it. Now I can tweak it as much as I want, because I UNDERSTAND. Im very very thankful to you and all the effort you made on making this videos, I know it must be hard and time consuming so a big thank you! Now almost every afternoon I sit down with my computer, iPad (there you give the class), notepad and pens, sit and listen while learning, writing all down to get it better. Here now is winter so hot coffee or tea, no sugar. THANKS again from Buenos Aires!!!!

[@daveharkin4731]

Paul I'm a little late to the party, but rest assured people are still watching and you're not talking to a wall. honestly these are the best programming tutorials I've seen on the net. at last somebody that can really teach. Thank you very much for these videos.

[@ianrice9403]

Love these videos. I'm pretty proficient at maths and engineering and physics and coding SEPERATELY - but I had huge gaps when trying to work out how they can fit together in this way. I have always been in awe at those guys who can just "build stuff" and make it work - it always looked like black magic to me! Problem now solved with Paul's videos. My knowledge has leapt forward in just one day and 4 coffees! So within 1 day of discovering this channel, I've ordered the Elegoo kit - nobody tell my wife please !!!

[@aubindejongh3913]

I have gone through a lot of coding tutorials and I must say yours are easy to follow and understand. I also tend to change my integer descriptions as I code and not just copying everything just to keep the focus up. I have my Arduino for more than 5 years now and since I found your tutorials I am again excited to build and program again.

[@kriskokko809]

Its 2020. There is a pandemic. I am a 20+ years engineer working from home. I love these videos. Yes, I watch these videos and do all the home works assignments like they are candy. MORE CANDY... please.

I admit I've been using the blue and green and even the white LED, but each time it was a special occasion, it is when I learn something new. BOOM!!

@@paulmcwhorter OH NOOOOOOO!!!!!! Pretty excited you replied I didn't even think you read these comments any more, ban me if you will lol I'll just use my buddies account to continue learning from you, thank you again for all that you do

[@gileskomm]

Hey Paul, I bought an Arduino after wanted to monitor various things in the garden and after finding your series, I have resisted the temptation to skip ahead and I'm going through the process and learning as I do. I've worked in the IT industry for close to 30 years and finally I (almost) understand binary. Trust me people are watching and learning.... BOOM!

[@tautvydas3364]

So I bought "The Most Complete Starter Kit UNO R3 Project" from ELEGOO. Then I decided to to find tutorials to learn how to use this kit and I came up with your videos. Now I am doing these daily after work(one or two tutorials a day). I watch the video then play some music in the background and try to do everything myself. This "teaching" method seems to be working well. Everything that I believe that might come up important (list of variables, IF, Dimmable LED etc.) I copy to the notepad and save them in the "arduino" folder. So the baggage of knowledge keeps growing everyday and nothing is missed :) THANKS ! P.S. The sad thing is that in the beginning the first videos had around 621k views and now lesson 17 has only 53k :(

[@liamboland2307]

Hi Paul I learned my electronics in the 70's. No micro controllers. I have many times to master Arduino and failed. You teach the basics very well. I am on lesson 16 in two weeks and keeping up. Confidence growing. Liam in Ireland

Glad to hear it!

[@thefierceninja2557]

the second I started this episode I got an ad that said "what would you do if you got 2 more hours?". The first thing that came to mind was "I would spend it on this series". Amazing teaching skills Paul!

[@MardinBodley]

I like the way you deliberately make errors . It is a great way to teach.

[@paulmcwhorter]

Yes, deliberate errors . . . thats it, I never make mistakes in real life.

[@louderone6042]

You are most definitely being watched. I like your videos and learning quite a bit. Your structure going from the simplest concept and gradually going upwards in difficulty, is a great thing, in my opinion. I love your homework assignments, as well. Having an old electronics background, the lessons with the homework I always expand farther than your assignments. For example, I turned your blinking LED assignment, into a set of working railroad signals. I wish you could see them. I will now reduce the amount of code with your FOR and WHILE loops. You do great work and are much appreciated by your followers. Keep up the great work and have a blessed day!

[@clementerosauro9127]

the little dot-connecting at the very end has been more usefull than some semesters in college!

[@ianrickard9480]

The example you gave at the end of the video re a thermometer and fan is exactly one of the projects I'll be adding to my system.

[@stevencureton2232]

Paul, just wanted to give you a shout out. I viewed your video series several years ago and loved them. The only problem was I didn’t follow your advice totally. I gave up Arduino and decided to get back into it. This time around I’m following everything you do to a tee and find myself really learning how to code. The number one “pearl” was to create variables for everything. I thought that you were being redundant but now realize the only way to learn Arduino is by following your recommendations and do your homework assignments. You won’t be able to code more complex sketches unless you have a platform from which to start. You have provided that platform for me and I appreciate it. Thanks for the great videos. I love them!

[@080396001006]

i have only watched the first 16 (well 16 and a half) of these lessons and i got the circuit and explanation to connect a dc motor to arduino from a book included in my kit. i combined it with what i learned from you on potentiometer and made a speed control for the dc motor. to anyone reading this comment, continue watching and learning and i promise it will pay off :D

[@aidanhanlon6290]

Video series is great! Going through all the basics in an easy to follow lesson format that is a good length has been super helpful for me. I will say that the "accidental" missed semi colons and variables get a little redundant after awhile but I understand the point of it; I would hope 17 videos in those of us following along aren't needing to be reminded of this every video. All in all really appreciate the uploads, thanks!

[@justinwhite2910]

Mr. Miyagi with the wax on wax off method of teaching is really cementing this all into memory. THANK YOU PAUL.

[@TheFalconJetDriver]

After I built and coded this project with a red LED and it worked, I changed the LED to Blue because it was so special because the project Worked🎉 This lesson came just in time for me because I am building a automated blast gate dust control system. The “while” statement is more user friendly to me.

[@chrisingram7277]

What is a blast gate? You've got me thinking about some automation in my workshop.

Hello! I really appreciate your excellent tutorials! They are priceless!!! After I completed the "while" loop assignment, I rewrote the program using "for" loop and "if" statement. It gave me better sense of these three function. I just bought the kit a week ago for my son who is in middle school. He is also really enjoy to learn it from your lessons, and he completed lesson 15 last night. we are both addicted to it 😁. My husband is learning it well, but he is at a slower pace. Thank you again! I hope we will finish all your arduio lessons!

[@longdongsilver4719]

Don't worry. We are watching and we are learning. A lot. In fact, I must admit that you changed my life. Since years I thought Arduino is too complicated for me and you made it so simple that I changed my opinion and bought the kit to follow you. Thank you for your time and for your refreshing way of teaching.

[@EthanElkorr]

Love your videos Paul McWhorter!!!

[@keithbrown162]

Just finished tutorial 17. Once again well done! I’m just blasting through these lessons. A thought, sometimes as I am following along, I can’t see how you wired things up and your comments on left leg of a LED can be confusing instead of short or long leg. So maybe if you drew an engineering diagram of the circuit, then I could pause the video on the circuit, build it on my breadboard, then restart the video. This has the added advantage of teaching your followers about circuit diagrams and symbols. This far into the lessons, you shouldn’t have to keep showing us how to plug things together. If you do, then we probably aren’t absorbing your instruction. Also, thank you for your reply about Patreon that I had questioned about earlier. I plan on helping you out there.

[@Win52D]

Paul, I agree with your assessment of While loops over For loops. I have programming experience using both and generally prefer while loops and sometimes switch functions. I admit is cheated on the earlier assignments that called for redundant code copying for blinking lights; I used While loops. Keep up the good work, I am enjoying the series.

[@Mrgasman1978]

Such great tutorials..i am enjoying them so much. I recently made a small project based on this lesson where i had a light sensor and a motor. Whenever the light sensor was detecting dark, the motor was turning on and vice versa, if the light sensor was detecting brightness above a certain number, the motor was turning off...this example helped me so much!!

[@stilesmcgraw]

This one was tougher than most. There's actually quite a bit here. Some of it is repetitive and I had to take some extra time to try to understand why. The best way was to make several attempts to rewrite the program from scratch over and over again until I understood exactly what the commands were doing and when it needed to be done. All in all, I think you are the best teacher I have ever had.

[@lewisencompos205]

Hi Paul. While I agree the While loop has its unique set of powers, I think we need a better example of the while loop for this example. Since the Arduino uniquely loops in its natural execution it becomes a bit muddled to use it where an IF is much more efficient and much less (more readable) code. BTW, I love your tutorials... I'm 55 and love the connected science and math. See My replacement example for tutorial 17. int potVal; int delayTime=100; int potPin=A1; int redPin=5; void setup() { // put your setup code here, to run once: Serial.begin(9600); pinMode(potPin, INPUT); pinMode(redPin, OUTPUT); } void loop() { potVal=analogRead(potPin); Serial.println(potVal); if (potVal>=1000) { digitalWrite(redPin, HIGH); } if (potVal
