Hi Paul You obviously want to "make a difference" and as a Christian since May 1956, I can tell you that you are doing that. Your first lessons were good, these are outstanding. If I had had a teacher like you I would probably not have flunked Maths at school. I have two objectives. I like to make stuff so the first objective is to add some "bells and whistles" to my current project that will probably take until the end of the year to finish. I have already learned enough to be able to do that. So thank you for that. The second objective is to use what you are teaching us to program an arduino to add functionality to a metal lathe I have converted to run using a CNC program. I am actually 10 years older that Paul from Brazil. I am in good health, an optimist and know that while other bits of us deteriorate with age, our brain can continue to function if we are prepared to stimulate it. Thank you Woodie

[@colepdx187]

I haven't written a single line of code in almost 10 years. I can't wait for my super starter kit to arrive. I started programming in 1973 on an HP9000 mainframe using COBOL and BASIC. My last contract was with Intel in 2009 and I was using C++ & MFC. What a long strange trip it's been.

i realize this is way late but if youre still prototyping tinker cad has a free digital board you can use for prototyping and has a digital version of all the components.. though you're probably a seasoned professional by now 4 years later lol.

[@terencebarber4269]

Hi Paul, at 76 I have decided to learn something new (i.e. arduino). Completed the homework but I used 5 led's instead and all worked as expected. Excellent lessons and thank you for the in depth explanations. Keep up the good work.

[@crowant3717]

that's very impressive props to you

[@vwwwvv2383]

I do the same as you when progamming these binary counters, but instead of doing the same command for the LED and only change the necessary, for example: digitalWrite(pin1,LOW); digitalWrite(pin2,LOW); digitalWrite(pin3,HIGH); delay(1000); digitalWrite(pin1,HIGH); digitalWrite(pin2,LOW); digitalWrite(pin3,HIGH); delay(1000); Instead of repeting the same command for the pin 3, I don't add the "digitalWrite(pin3,HIGH);" unless it turns LOW. This is nice to not keep the code too "wordy" but it's easy to lose the track of the counting when you're doing this. For last, I need to thank you so much for your lessons, its really making me learn something from the scratch and understand. Great work, Paul, and sucess!

[@JungleCruiseSkipper]

I did it along with you. I am just starting out and don't even know where to begin with your homework assignments. Your video is over 30 minutes long and you knew what you were going to do, imagine me trying to guess all day long how to go about it. I like the speed at which you teach, I'm able to keep up without having to pause too much.

[@samueltheprogrammer6145]

It is ok if you can't finish the homework on your own. but you need to try to do it and if you can't then watch the solution or if there is no solution then just get help from us in the comments below the video, I am always here to help. When I was starting Arduino I was having trouble too, but I did not give up, I kept pushing, then it started to get easier for me. Samuel

[@davehollingshead3450]

Paul, Thank you for the in depth lesson on the binary system. I appreciate the method of teaching because it helps me understand the content. I followed you first series of lessons up to the distance meter and plan to build a few of these for Christmas gifts this year. Looking forward to your next "new and improved" lesson.

[@stilesmcgraw]

I took the homework and did my best to write the program trying to use integers to do the work for me and also make any changes easier. I actually found this very easy to do and didn't take as long as I thought it would. I looked forward to seeing if you were going to cover the homework so I could compare how you wrote your code. Some people have told me I got it backwards, but I wanted it to match the binary chart you drew out...counting right to left. I agree that we should do the homework on our own. Following along in my opinion, can kind of hamper your confidence and creativity in the future.

[@thomasperusi7854]

I am a retired avionics tech fcc and A/P mechanic for 43 years. I have done bench work and line work with electronics and have always wanted to learn deeper on the workings of the stuff I fixed. I know binary and many of the things your teaching but learning the Arduino and programing side you make it so easy to understand. I bought the mega kit and watching your videos will get me to the point of engineering digital experiments ive always wanted to do. Thanks so much for sharing your knowledge with us.

[@paulmcwhorter]

Great to hear this! Love to hear people are actually learning from these classes.

[@Joe_Parmesan]

Making the 5-bit LED counter helped, as I was able to notice the pattern you described: For the ones column, the 0s and 1s alternate every other move. For the twos column, the 0s and 1s alternate every 2 moves. For the fours, it's every four moves. For the eights column, they alternate every eight moves, and for the sixteens column, it's every 16 moves. Pretty neat to see it laid out!

[@trailerkeller6760]

You explain this so well. It makes me happy that I’m gonna have a new hobby where was this kinda teaching in my robotics class? My High School has a robotics class and all we learned was to play with LEGOS, I feel like my school robbed me of building and being creative. instead we could have learned how to program and make the robots go. I’m so happy I finally found what I love.

Hello Paul, Being a professor my own self, I am even more relishing the way of your teaching :-). The pace is just fine, and my long-long mission of doing logics myself is taking its shape. Thanks. Yes, I could do the homework well before.

[@jusko2092]

Everything is great. Honestly. When I bought my Arduino kit the other day, I was super overwhelmed with other tutorials. A lot of them operate on the pretense that we already have an understanding on how everything operates: a picture of the circuit is shown and the libraries/code are just imported and copy-pasted in. I love the way you've broken things down into simple, easy to understand (and easy to work with) information. I'm having so much fun experimenting with the homework concepts and applying what I know and what I've learnt from your lessons. Thank you.

[@paulmcwhorter]

And keep going . . . lets see you make it all the way through lesson 68

I did it during "homework" and got it first try, only difference is I ended up spreading the LEDs on the entire breadboard so it's a bit messier but it doesn't matter as long as it works. Thank you Paul!!

[@rodrigooballe]

I have not encountered many individuals like you in my journey of learning. I must express my gratitude for your unmatched and invaluable teaching methods. Your videos have been of great help to me, and I recently discovered the ease of understanding things when approached with critical and logical thinking. With the aid of your videos and some Arduino and C manuals, I was able to solve the problem of adding an additional LED to my board and modifying what I had already done, which included the digits of 0 at 31. Thank you once again for your guidance and support. Although these videos are 4 years old, I have decided to watch them all and learn everything that's taught here.

I'm watching these videos even though I'm very comfortable with these concepts, but I have found you go further in depth on some subjects that most tutorials just graze over. I am finding these very helpful in knowing how things are working "under the hood" as you said. Thanks for these videos.

[@elloco99999]

Hi Paul, first I'd like to thank you for doing these tutorials! I've been a professional developer for almost 2 decades now so the programming is way too easy for me, but I'm following the tutorials to help me get a better understanding of the Arduino and what it can do. I did do the assignment before coming to this lesson and had no problems with it. I used a couple of for loops to spare me a load of copy-pasting :-) I do always like it when I'm learning something I get assignments to try and figure out for myself. You learn much more when you have to think about it instead of just following along with the video. A little tip about variable names, naming a variable pin2 (etc) might not be so useful. If you decide to switch to a different pin later, you have an incorrectly names variable that might be confusing. Better to name the variable for what the pin is used for.

I watched and took notes on the first 5 lessons without any hardware set up or software running. Today I decided to go for it. My version of the IDE is a bit different from the one on screen. I get no happy orange and blue if enter correct key words and proper syntax, but just get error messages when I try to compile if I fat-fingered something. Coding is not so drastically different from the BASIC that I taught myself 35 years ago. I haven't coded in 30 years. Feels good to exercise that portion of my brain again. Thanks very much. I'm a retired Mechatronics engineer that needs to keep my mind active, or I feel dead.

Hello there again, Chief! This is the code that I had written after you gave us the assignment last week, even before you uploaded this video. I intentionally kept the sets of the four commands in one line, using a full screen IDE, so that I has a visual impression of the binary counting. I hope it meets your approval. int oneLED = 7; int twoLED = 9; int threeLED = 11; int fourLED = 13; int wait = 1000; void setup() { pinMode(oneLED, OUTPUT); pinMode(twoLED, OUTPUT); pinMode(threeLED, OUTPUT); pinMode(fourLED, OUTPUT); } void loop() { digitalWrite(fourLED, LOW); digitalWrite(threeLED, LOW); digitalWrite(twoLED, LOW); digitalWrite(oneLED, LOW); // this is digit 0 delay(wait); digitalWrite(fourLED, LOW); digitalWrite(threeLED, LOW); digitalWrite(twoLED, LOW); digitalWrite(oneLED, HIGH); // this is digit 1 delay(wait); digitalWrite(fourLED, LOW); digitalWrite(threeLED, LOW); digitalWrite(twoLED, HIGH); digitalWrite(oneLED, LOW); // this is digit 2 delay(wait); digitalWrite(fourLED, LOW); digitalWrite(threeLED, LOW); digitalWrite(twoLED, HIGH); digitalWrite(oneLED, HIGH); // this is digit 3 delay(wait); digitalWrite(fourLED, LOW); digitalWrite(threeLED, HIGH); digitalWrite(twoLED, LOW); digitalWrite(oneLED, LOW); // this is digit 4 delay(wait); digitalWrite(fourLED, LOW); digitalWrite(threeLED, HIGH); digitalWrite(twoLED, LOW); digitalWrite(oneLED, HIGH); // this is digit 5 delay(wait); digitalWrite(fourLED, LOW); digitalWrite(threeLED, HIGH); digitalWrite(twoLED, HIGH); digitalWrite(oneLED, LOW); // this is digit 6 delay(wait); digitalWrite(fourLED, LOW); digitalWrite(threeLED, HIGH); digitalWrite(twoLED, HIGH); digitalWrite(oneLED, HIGH); // this is digit 7 delay(wait); digitalWrite(fourLED, HIGH); digitalWrite(threeLED, LOW); digitalWrite(twoLED, LOW); digitalWrite(oneLED, LOW); // this is digit 8 delay(wait); digitalWrite(fourLED, HIGH); digitalWrite(threeLED, LOW); digitalWrite(twoLED, LOW); digitalWrite(oneLED, HIGH); // this is digit 9 delay(wait); digitalWrite(fourLED, HIGH); digitalWrite(threeLED, LOW); digitalWrite(twoLED, HIGH); digitalWrite(oneLED, LOW); // this is digit 10 delay(wait); digitalWrite(fourLED, HIGH); digitalWrite(threeLED, LOW); digitalWrite(twoLED, HIGH); digitalWrite(oneLED, HIGH); // this is digit 11 delay(wait); digitalWrite(fourLED, HIGH); digitalWrite(threeLED, HIGH); digitalWrite(twoLED, LOW); digitalWrite(oneLED, LOW); // this is digit 12 delay(wait); digitalWrite(fourLED, HIGH); digitalWrite(threeLED, HIGH); digitalWrite(twoLED, LOW); digitalWrite(oneLED, HIGH); // this is digit 13 delay(wait); digitalWrite(fourLED, HIGH); digitalWrite(threeLED, HIGH); digitalWrite(twoLED, HIGH); digitalWrite(oneLED, LOW); // this is digit 14 delay(wait); digitalWrite(fourLED, HIGH); digitalWrite(threeLED, HIGH); digitalWrite(twoLED, HIGH); digitalWrite(oneLED, HIGH); // this is digit 15 delay(wait); }

It worked great. Anyway I thought I would get back into Arduino as something as a hobby but I forgot most of it so I started watching your videos from the start and I have learnt so much already in these first six videos, I surprised myself when I noticed that you hadn't put the delay as an (int) :) as I had already done the homework and I had put it in as a (int). This proves your teaching method is working. Thank you so much for your time to make these videos, Great job !!

Thank you, Paul - I have a model railroad I am trying to add crossing gates with lights using the Arduino, IR sensors, and relays. I am only on Tutorial 6 but I know this has already given me so much confidence. Can't wait to see more.

Hi Paul, now retired (67)and come from a mechanical Engineering and IT training and installation background. So during Covid lockdown here in the UK to keep me mentally active i have just started looking at the Arduino world. I find your videos easy to follow and enjoyable to watch. Typical of retired Techies i did your lesson 5 home work and failed miserably 😫 . Poor connections and short cutting the cut and paste, using find and replace. ooops lesson learned engage grey matter and stop being lazy. now off to do the 8 bit coding. many thanks Bill.

Programmed and built it! Some minor syntax snags but got it working in an hour. Thank you!!! I spent decades as a PCB layout designer, but you don't learn this stuff doing that. What I do have is immense familiarity with the discreet components. So much fun! I feel like a kid! LOL

[@jakedomoto6802]

Hey Paul! First of all thank you so much for the work you put into these tutorials. I found you on KZbin through a quick search and after watching your first tutorial I ordered my kit and jumped right in. Today is my second day and I just finished my LED binary counter. (I actually did mine as homework so I wired it differently on the breadboard and only did 1-10) but it turned out fantastic and worked perfectly the first time. I was so proud I posted it on facebook and snapchat ha ha. I can't wait to see what else you have in store for me to learn. PS: I always get a hot coffee when you say to grab an iced coffee. Hope you don't mind!

[@ethmanolboy6816]

Hi Paul, I also did the homework from lesson 5 and pretty much did all the same stuff you did by accident, with the only exception being the naming of the 'int' and the lay out of the LEDs. These lessons are very helpful, easy to follow and are just a great way to wind down after a long day, thank you.

[@epic_kenobi_gamer6971]

I did do this as my homework and I laid mine out in series in the one row rather than across the board and in the column in which I had my first LED and under that the ground I connected the rest of the LED's too that column and it worked fine, so it was nice to watch the different way in which u have done. Loving these tutorials.

Hi Paul, I was looking for a basic electronics kit for my grandson and stumbled onto your tutorials. I have always been fascinated by electronics but never had the time or resorce to look into the subject. I have now watched the first 6 of your tutorials and am getting really hooked. Ive not purchased a kit as yet, so have not been doing my homework either. (sorry) I am 7 years younger than Roberto from Brazil, so feel I am never too old to learn new stuff! I'm 68 and from Leicester England. My grandson is 5 so I shall wait a couple of years befor I introduce him to your very thorough and easy to understand tutorials. Thank you.

I'm about a year after you posted this, but since you asked, I do try to do the homework assignments. I'm starting from scratch with your video series being the full extent of what I know about wiring, breadboards, and arduinos. That being the case, so you know, I have been able to do all the coding with what you've taught, but I was not able to fully do the wiring from Tutorials 3 (using 3 LEDs) or 5 (using 4 LEDs) as I did not know until this lesson how to connect multiple lines to the single ground on the arduino using the (-) row on the breadboard. These lessons are fantastic, and are perfectly paced and have the exact right amount of explanation. Very well done, and very much appreciated. Now excuse me while I go get some more iced coffee and prepare for Tutorial 7.

[@user-hv2pw1fi9v]

Hi Paul, your teaching is amazing! Ive just completed the homework for the LED clock 0-31, so clear and precise, taking the time to understand how things are actually working has made it so much easier, also the laying out of circuits, the use of the whole breadboard, the copy and paste tips. These are just so helpful!

[@cboyles]

Hi Paul! Your Lesson 5 was so excellent that I was able to do the homework on my own. I then “cleaned” it up as I followed along with you in Lesson 6. Still amazed at how exciting it is it turn a light on! Thank you for the great lessons.

[@tomroberts3851]

I completed the homework with no support, there's no way I could have done this a few days ago, thanks so much, I'm loving these tutorials!!!!

[@thomasperry772]

A friend of mine recommended watching your instruction videos to learn to code/program arduino. Best decision ever. Your teaching style is impeccable. I completed my homework from the last video a little differently. I have a 500 ms pause between each number and my LEDs come on for 500 ms. I never thought I would even be as far as I am right now and you have made that possible. Thank you so much!

[@golanoski1]

I was able to complete the assignment before watching this video (I even remembered to declare a variable for the delay :-)). My ground was done less efficiently but it still worked. This review is extremely valuable as a tool to learn where we may have gone wrong and what could have been done better, so many valuable tips (such as using the long ground row), I got an Arduino for Christmas from my wife so I could learn to teach our young daughters about electronic prototyping, programming and S.T.E.M in general when they get a little older (currently 4 & 1y.o). this has been tremendously helpful. thank you again Mr. McWhorter.

[@TheSelfUnemployed]

Did the homework on my own and i am super grateful for the lessons you provide us! Production value is top quality in 2022!

[@thomasgalligan5662]

Done this on my own but still watched this video to verify my work. Love your teaching style I have picked up more from this video series so far than I have picked up on my own. Thank you

[@nathantshava4921]

Hi Paul, I completed it before watching this video. I had it all working exactly the way you had. I am absolutely enjoying the sessions. Thanks so much.

[@gene328]

I've been trying to program an Arduino for a long time, and I just didn't get it for some reason. After watching you a couple of times I started getting it. I'm 75 years old and it's getting a little harder to remember and understand things. Now I know it's not my age it's that I just didn't understand. It has something to do with you being a really good teacher. I did the homework for lessons 5 and 6 and was able to write the sketch on the homework for lesson 6. I didn't quite understand what you wanted and I made a few mistakes but was able to find what was wrong and fix it. It didn't take long and I got it working. I am really happy about this now. Thank you for being there. Gene

Замечательные уроки. Спасибо Paul McWhorter за ваш труд. Я пересмотрел много уроков других авторов по ардуино. но остановился на ваших уроках и изучаю их. пересматриваю по несколько раз. Все очень доходчиво и интересно.

[@paulmcwhorter]

Я очень рад, что они вам понравились. Спасибо за комментарий. Да благословит Вас Господь!

[@57beanyboy]

As an experienced teacher myself and as a Principal that has managed many probationary teachers, I can say with some authority that your lesson plan is well set out, your speed of deivery is just at the right pace, your tone of voice is reassuring, your knowledge level is obviously very high and the video presentation is outstanding. I am really enjoying being part of your class, thank you Paul.

[@PrivateEvans]

Was able to write it myself between videos thanks to the first lessons. Then watched and compared your method. Really enjoying your clarity of explanations and building of understanding rather than just what to do.

[@paulmcwhorter]

Fantastic!

[@user-xo2on4ru1c]

Hi Paul from Scotland just started with ardunio trying to learn for my flight sim the way you teach i think is wonderful so easy to follow you thank you

[@dcrickerson7611]

I'm enjoying these and yes I do my homework. I'm 72 years old and have been retired for ten years. You're a great teacher Paul.

[@paulmcwhorter]

Wonderful!

[@user-hm3ft7cr3d]

Love the work you do Paul. very simple and very clear. it could seem boring at times but going through all steps and making sure we understand is great and so important. thank you for your work 😊
