LESSON 3 - Arduino For Loops and LED Circuit

[@quantumsoftware1424]

I am a hard core programmer and I am trying to learn Arduino. I've watched quite a lot of beginner tutorial. I find yours to be the most educative one because your presentation style is from the intention to teach and not to impress. Really appreciate it. Thank you my dear teacher :)

[@omaxshendy5732]

i am a beginner programmer , and i support this sentence a lot! 2019! :P

[@215alessio]

yes he is way better than mario bros from RS

[@VasilisMathas]

You are the definition of Teacher , thanks

[@Michl234]

You really are a teacher! You can explain the basics clearly. And you know how to control through your own knowledge and still tell the ignorant how the basics work. You have the very right skill to teach! Thank you!

THank you

[@theaeela2590]

Mr Paul, I had not had any experience of Arduino programming before watching your lessons. I appreciate your effort, you are the most respectful and intelligent teacher I have ever seen. Go on!

[@rajeshaer]

My son is in the 8th grade and he is crazy about Arduino. IAM right away recommending your channel to him. Great teaching.

[@Sonu-ye5ux]

I have found it the BEST channel to learn Arduino programming.

[@asressaraia2340]

I bought the Kit and am following your program. I can not thank you enough for this effort and the wonderful results we are all obtaining from your training. I hope some day soon to find a way to express my appreciation. Thanks a Million. Asress Araia

[@koshakprontix5821]

I am a beginner and I like how you explain the material. You are the only person who explains it so that I can understand it. THANK YOU!!!

[@enredao_electronico2737]

I've working with Microchip for 10 years... I wanted to fully understand how arduino works since is a better approach for teaching kids.Unfortunatetly for me my brain only digest data in a Step by step & "Read and do" way. Mr. Paul you are an excellent teacher and fortunately for me I found your channel. Kudos !!

[@eggrute]

OMG, you are an amazing adurino teacher. so easy to understand, I like how you take pace slow. I also like you give us HW at the end of video so that I can review what you have done as well as I can create something else based on what you showed on the video. Thankyou^^. I will go to lesson 4 tomorrow. amazing video!

[@gregroberts6339]

I totally agree, I love the homework

[@flyzoome]

what is your email adress

[@ravikaviya1984]

Sir Iam a Assistant Professor(Computer Science) .What I feel after watching your video that you can teach coding to anyone. Iam learning how to teach, from you sir. You inspired me a lot. Huge respect from my side. Thank You. God bless you.

[@paulmcwhorter]

What a nice compliment, thank you!

[@exitritual]

As a complete beginner, this was super helpful; Thank you. I'm working my way through the course. This evening (using a 170 breadboard), I did a 5-to-3 blink with two white LEDs. I plugged in a 9v, put it in a ziplock (in case of rain) and then into the mesh pocket on the rear side of my backpack. Worked as a flashing safety light for an evening walk to the grocery with my wife. Super simple, but felt like an accomplishment.

[@paulmcwhorter]

@Matthew Miller - Thank you for the comments and kind words, and your suggestions. I know the standard is, as you indicate j++. The thing is I am really targeting these videos for my High School Freshmen who have not programmed before, and am trying to make things as familiar as I can to them. It is a balance . . . I dont want to teach them something that is not the way people do things, but at the same time, initially anyway, I want focus on making it understandable. My hope is to push these classed down to 7th grade in the next few years. I appreciate your comments, and hope you will continue to tune in and continue to give feedback.

[@amikomalania3406]

+Paul McWhorter Hellow, I'm from Georgia and i really enjoing wathcing yout great tutorial videos about Arduino. This really awesome and your teaching skills are also great. Can u give me some moere your videos about Arduino as i said i really find easy learn from ur videos and i want to learn much more.

[@giorgiaptsiauri9928]

Check out Paul's playlist, he's got more series.

[@pjiri961]

Literally the best way to teach (if you dont know how to teach your knowledge in simple terms you do not know NOTHING,,,Albert E.) i am 40yrs old,, and you are probably the best teacher ive met so far in coding...... For begesus sake this is the first time i feel i have learned some coding!!!! THANKS SO MUCH

[@TAIMURZAMAN]

Paul, you are doing great. I bought arduino 3 months before and couldn't used, but soon after watching your videos, i am now able to do lot of stuff

[@shorsoonjoe8329]

Paul McWhorter ,thank you. Arduino is a very good easy tool.but I wondered if we can make it more easier .dont need to care the capital,auto delay ,int or float ,I just input...everyone can do it,no need to learn.

[@10krishnadas]

A real Teacher who really wants to upgrade people, who are interested to know something more in the subject. Love you for your sincerity and broad mind. All the goodness to you Sir.

[@romikotchan]

you are one of the best teachers of Arduino on the internet, cheers from Argentina!!!

[@kyledebruyn703]

By far the best arduino tutor. Very informative, slow paced and challenging

[@nickwhelan2743]

I"m a reasonably old boy and so far without doubt iv"e found your tutorials really easy to understand and actually enjoy how you go about these lessons, i believe i have learnt more in one night than a week of trying, i will be following you as much as i can learning as many things as i can, having a background in electro mechanical i can see so many possibilities opening already,, a big thankyou to you, cheers from Nick

[@johnzudans7724]

Paul great stuff, I remember the old days writing fortran and basic programs , the diagnostics would only come out after punching out the cards and running through the mainframe. This real time capability is great tells you where your error is much better. Wish I was a kid again. I am 70 and will be one of your students. Thanks

[@paulmcwhorter]

I remember those days as well.

[@dbiswas]

You are just awesome teacher !!!!! You are not only knowledgeable, but you know how to teach. I love all your lesson and I am learning so much. Thank you so much for putting such wonderful videos.

[@jemshahe-learning]

sure

[@bhuvananambi8340]

You are the best teacher for Arduino. Eventhrough your video is log,it is very much worth watching. Thank you very much. You are the best. If I learn Arduino completely,I owe it all to you

[@EpicSpence]

I really like your teaching style. Your tutorials are like lectures, very comprehensive and detailed with emphasis on every point even if it's minor. Excellent work thank you.

[@RealReelzz]

Hey Mr. McWhorter. My name is Devin I'm 24 years old I have no education besides basic high school education. I'm in the construction field and honestly I can already see the toll its taking on my body, so about 3 months ago I decided to educate myself (I cant afford school). I first taught myself electricity which then sparked my interest in circuitry. which has now brought me to Arduino programming and I just want to let you know that you are doing such a service for people like me I wish I would have found you earlier! I'm not sure that you will even see this, but I just want to tell you thank you for what your doing I love everything you talk about on your channel. when I finish the programming I'm going to start the engininering or maybe the 3d printer ones. since I have a printer and I would love to just hear what you say but I don't want to drag this out I just wanted to tell you. Thank you and GOD bless you!

[@paulmcwhorter]

Thank you for the kind words and encouraging message. It is a real encouragment to hear that people are watching these and benefiting. Keep Learning!

[@RealReelzz]

Yes sir. keep uploading videos lol.

[@davidbgood2801]

I really have had a hard time learning the coding but I have really been able to follow you and under stand what you are doing better than anyone else I have seen so far on the internet thanks for these videos I am learning a lot.

[@visitcanada5885]

I wish my instructors watched your tutorials to get better at their job. Thank you for sharing your knowledge with us dear teacher.

[@paulmcwhorter]

Wow, thank you

[@daveboxwell3151]

Awesome teaching Paul. I am just starting in Arduino and have absolutely no experience in coding or computer languages. Following your tutorial I think I have compiled a program to blink an SOS signal in a red LED and to flash a green LED at the end of the SOS sequence. My ultimate aim is to program my electric start petrol bushfire pump to start and run by SMS signals. I haven't even got my Arduino kit yet but I have compiled the program with no errors based on your excellent tutorial. I have a long way to go in learning and your tutorials are an excellent resource. I love the way you intentionally put in errors so that we can them up and learn from them. Keep up the excellent work. Micah 6:8

[@gurpreetdol6511]

I love working with electronics, but watching this world engage itself into robotics, learning Arduino became an interest. presenty I live in Philippines and no one here teaches Arduino(neither in schools or institutions), so I was kinda discouraged, but when I saw your videos, I saw a great improvement in me, and you inspired me to pursue my interest in learning Arduino. the way you teach doesn't stress me out, and I don't get lost, you teach slow enough for a beginner to follow, but fast enough for him to be able to create several good projects within weeks. I really appreciate the way you teach and your hard work

[@sergiosilvaTuga]

Finally someone who actually teach me something!! thank you very much for sharing your knowledge.

[@basharalassad4589]

Paul keep going I’m almost finished

[@NR5P]

Thank you! This is the best tutorial I've found!!!! You are such a great teacher!! I'm just learning code and the arduino. I've looked at books and at other videos. I've came away with a lot of unanswered questions. Your video fills in those gaps and you actually tell people why and how these things are done rather than just "this is how it's done'

[@sohailmohammedpathan1194]

I am Sohail Mohammed from India. I teach Computer Science in High School. I am learning not only Arduino, but teaching skills as well from you. You are simply awesome. I am planning to do PhD in Security measures to secure data of IoT. Thanking you.

[@alankilgore1132]

Just trying out an Arduino project kit for the first time. These kits are a very good value. You commented about using "I" and "J" for loop variables. We are probably from the same generation of programming, age-wise, so I'm surprised that you don't know that tidbit of programming trivia. It came from FORTRAN programming. FORTRAN (from the 70s) had very strict rules for certain things, and one of them was that variables starting with the letters "I" through "M" were forced to be integers. Since loop variables had to be integers, programmers, myself included, started to use the letters "I", then"J", then "K", etc as our loop variable names. Remember that then (ya I'm old), we "wrote" programs on punch cards, so it was far easier to type an "I" than some long variable name that started with "I". I still use that technique, though it does date me! LOL

[@ClaudioBettinelli]

You are the best teacher on the net, Paul ! I learn Arduino code and English with you ;-)

[@dianaal-qassim3348]

Your videos are really very helpful, and easy to understand! I try to follow you at first then I try to continue on my own to see if I actually understood and then compiling and seeing that the circuit actually works brings me so much excitement. Thank you so much!

[@taokodr]

If I had a dollar for every time I encountered capitalization issues in my variables, I could probably retire! :D Kudos to you for keeping that in the video and teaching an important side lesson; it's the little bugs that get you. Loving this series! :)

[@trevh8662]

really interested in constructing and coding. So far your lessons are top notch on talking people with no idea how to start! thanks

[@erygion]

Thank you Mr. Mcwhorter, I didn't think I could learn anything new from a basics video and boy was I wrong! You're a great teacher sir, I'll be doing your whole course. Thank you again.

[@ElementofWorship]

Thanks for the great videos!! I may not be able to afford formal schooling right now, but I'm so thankful that I can still learn all sorts of things thanks to great teaching videos like these. :)

[@yajurphullera9396]

Thank you Sir. Your lessons are amazing. I m a Student and want I find your lessons very helpful. Keep doing the good work.

[@krakadoros8605]

Hello, my TEACHER.( Allow me to call you like this). You have, what ancient Greeks said "ΔΑΙΜΩΝ" (in teaching). I mean you have pure talent inside you, and a divine spark. Now, here is 4.49 am, and i am still standing for watch your 3rd lesson. I am very happy to found your videos. (Thank you )^ 100

[@paulmcwhorter]

Thank you for the kind words, and words of encouragement!

[@mattamiller]

I really enjoy your videos Mr.Mcwhorter. You teach in a very thorough and easy to understand manner. I hope you continue to produce these videos, I'm sure they will become a hit in time. The only comment I can make is on the for loop. Most of the time an increment statement is done via "j++", but it all works the same.

[@intechdoacademy8487]

Paul, you are an amazing instructor...Love your conversational style to share your expertise on Arduino.

[@joemusicman64]

I just bought one of these kits and have completed your first three lessons. Very cool. I have been a PLC programmer for automated machines and robots for years. I really find it enjoying to build these little circuits and write the programs. Reminds me of my microprocessor class in college but this is much more user friendly. I don't have to program in hexadecimal (Z80).

[@paulmcwhorter]

Very cool!

[@amongussussy9542]

Thank you for the helpful tutorial! Very informative!

[@rajeshshejale2710]

Sir, Thank you so much for teaching so better, before this I tried some paid training's but even that did not help me out , But this definately taught me a lot , and is helping me for my project.

[@MaheshSharma-yp6wr]

Sir,you are awesome..your speed is excellent for a new programmer or an experienced programmer to learn the basic in arduino. Thank you for your lectures sir..

[@blueprinttblueprintt9704]

I can't Thank you enough for taking the time to educate us. I love the way you teach....

[@randywetzler5976]

Thanks for the lessons Paul, great job. I also ran into issue of the "for" loop clause not turning orange. Surprisingly after declaring the integer variables as shown by Paul in the video the code worked even though "for" stayed gray in color. I used the letter "c" (i associated it with "c" in the word count) for the variable. I am running version 1.6.5. This stumped me for a good while until I went ahead and declared the variables and tried it anyway. Maybe someone from the Arduino community can explain whats going on. I'm in my 50's and having fun learning this stuff.

[@MrHydyr]

@Paul McWhorter , Hello Sir, I'm super fresh to programming and your tutorials are awesome! Thank you for sharing them with us. By the way. By the end of the second lesson, I've did the same, just, instead of doing extra loops, I've just adjusted the time for each LED and it worked fine.

[@shoaibmazhar6859]

Thank you so much Sir Paul. I took 3 lessons and done all as taught by you. Even did assignment too :) Stay blessed

I put on 6 instead of 2 LEDs, and it WORKS!!

[@stephenadams1714]

This guy breaks it down very good explanation of Arduino.

[@md.kumrulhasan1044]

Two LEDs (Red and Yellow) blinking with a time gap is quite easy. It would be helpful for many if you make another video to " Blink two different LEDs at the same time with different blinking rate". That'll make people understand executing two loops at the same time.

[@johnl.khawbung2056]

[@fransdullemeijer143]

Very good and I learned the internal loop. And making the pre setting list of integers. Very handy to write and work properly. The only cosmetic thing was the red coloured breadboard rail you used as GND. I often use 2e hands LEDs out of my component box. Recognizing the minus of LEDs is also possible determining the plat part of the LED housing. I prefer that because of the 2e hand status. But this are not important things. Your lesson was excellent! greetings from Holland. Frans Dullemeijer

[@chickendude1695]

is it just a different colour

[@chestercwright6070]

What is the answer why the "for" doesn't change color, because my for stays black.

[@verhuur2012]

Best teachter all times, Thank you

[@broderp]

FIGURED IT OUT: LOL, I forgot the ";" after declaring the int "numYellowBlink=3 below. This fixed it. Can someone explain why it halted and highlighted the "void setup()" line? Debugging can be tough I see!! So far it makes no sense given the error. This is the BEST tutorial on learning the basics of the Arduino. I feel like I'm actually in a class room. I love your teaching style and your on purpose mistakes to reinforce best practices. THANK YOU!! ORIGINAL QUESTION: Did they change something? Creating the first "for" statement works. When I add the second one to control the number of flashes for the second LED, it will not upload. It halts on the "void setup()" line below and states "expected ',' or ';' before 'void'" . My curvy brackets all seem to be in the right place and I do not know why the failure is in the line that it is. Here is the code: int blueLED=7; //Declare blue LED as int and set to pin 7 int yellowLED=8; //Declsre yellow LED as int and set to pin 8 int blueOnTime=250; //Blue LED on time int blueOffTime=250; //Blue LED off time int yellowOnTime=250; //Yellow LED on time int yellowOffTime=250; //Yellow LED off time int numBlueBlink=3; int numYellowBlink=3 void setup() { pinMode(blueLED,HIGH); //Sets Arduino pin 7 (blueLED) to High pinMode(yellowLED,HIGH); //Sets Arduino pin 8 (yellowLED) to High } void loop(){ for(int j=1; j

I wound up watching 8 in a row, but then realized I had reached a saturation point and needed one in front of me to start working with, so I ordered the kit. Should be here any day now and will then continue. Another fun adventure. Can't wait to start incorporating this into my woodworking. Starting to get an idea for an LED grandfather clock.
