Man finding your channel is like finding the holy grail. Just so you guys know, Paul's got Raspberry Pi videos, and all sorts of other topics for later. Thank you sir, schools would be better if all teachers were like you

[@jakeklic]

I just found his channel and its so great!

[@davidlee9924]

my teachers don’t even teach they just make us watch youtube and learn that way while they sit on their phones

[@roberthead127]

YEAH wish my Teachers where like Paul

[@minipop1138]

I would have got into this hobby much earlier if I had a teacher like you. Well done!

[@sansaningidanbayero6500]

I AGREE 99%. THANK YOU PAUL!

[@gramofonomanek]

His patience and way how he is explaining is great.Plenty teachers lost that gift.You want to listen,old school.

[@RikMeloen]

Tip: at 16:39 where he is changing all the numbers, you can just do Crtl+F and change everything at once.

[@Tryant69]

Very nice tip! thnx

[@jobsanjose1188]

thaaaaaaaaaaaank you so much

[@stuhastie1719]

Hehe, awesome. If you happen to minimise that function, and if you Ctrl+F again, it hides from you till you drag it off the bottom again

same with me im 12 but im just learning arduino for fun, this guy is so easy to listen to.

[@WarenaiSai]

I'm a mechanical eng. grad student just getting into Arduino. Thank you for your dedication to making these great videos Mr. McWhorter!

[@jaws2858]

I’m 58 years old, this is my first time working with programming and I need to tell you this is the best class I’ve ever had! Thank you! I’m stoked.

[@Ewecnt]

After 30 years as an electrical technician I have a solid understanding of the components but your tutorials are still interesting and enjoyable to watch. I’m new to the Arduino platform but not entirely new to programming even though I have never worked in C++. So for me your videos are an extremely good way to absorb these new skills at my own pace. In fact what ever level someone is at you allow them to go at their own pace. Good work! Keep it up. And thank you.

[@senrinakamura4456]

I know how hard is teaching, so I don't criticize my school's teachers. However, every teacher should learn how Paul teaches. You're amazing.

[@billlaird7332]

Outstanding series. Ordered my Arduino starter kit. Will be here tomorrow. A couple of constructive criticisms. 1. SOS was informally initially recognized as meaning "Save Our Ship". As it became more wildly used as a universal distress signal on land, sea, and air it was reinterpreted as "Save Our Souls". An extension of this idea is when aircraft pilots file a flight plan with the FAA, one of the items in the flight plan is the "Number of Souls on Board."" As a HAM, or licensed Amateur Radio Operator, I want to offer the correct timing spacing in Morse code for dots, dashes, and spacing. 1. The length of a dot is one time unit. 2. The length of a dash is three time units. 3. The length between symbols (dots and dashes) of the same letter is 1 time unit. 4. The length between letters is 3 time units. 5. The length between words is 7 time units. The length of the time unit varies with the speed of transmission. The time unit for a transmission speed of 5 words per minute is 4 times the length of the time unit for a transmission speed of 20 words a minute.

[@niggaz4life635]

best teacher i've ever got

[@Enginmann]

me too

[@tothydroponics6733]

I'm a former teacher and I just have to tell you man that I love your style brother! Great Job! You assume the student knows nothing and that they should learn EVERYTHING!

[@paulmcwhorter]

Awesome! Thank you!

[@locutussmith]

Sir as an elderly student (69 years of age) may I wholeheartedly thank you for your clear and precise teaching, many thanks from the UK.

[@xxxalphaeverythingxxx8489]

Nice

[@Enginmann]

this is the best Arduino tutorial series in the world MR Paul, your are an AMAZING! person

[@Randy2747]

For people starting his course just a bit of advice.... After each lesson I print out the script on paper and write noted down on it. Install in a folder that way I won't forget and if I do I can go back to see what Mr. McWhorter has taught me 😉👍

[@lucast3006]

I’ve seen other channels go through Arduino basics and yours is the best by far! Having a lot of fun learning this.

[@paulmcwhorter]

Glad you enjoy it!

[@evolutionsfake]

I must say I am an old fart considering that I am a husband and a father, and I was pleasantly surprised to easily see the transition not just to memorize code, but finally understand why people use variables, and greatly appreciate you purposely giving us a hard time because you know we'd want to learn from it. This is the most pleasant video I have ever followed along with and I can feel myself getting smarter with these videos. I'm not just watching him I'm programming and putting stuff together. Thank you!

[@star_labs_official]

i think the old fart part is true, thats it

[@hibaboubia2930]

​@star_labs_official why so salty dude. The guy just expressed genuine excitement to learn. Please try being more gentle with people. Bless you❤

[@cboyles]

Appreciate these lessons so much and can’t describe the joy it brings me to be able to figure out how to do the homework assignments! The Elegoo “Most Complete Starter Kit Mega 2560 Project” was a 62nd birthday gift last year. Using my university summer break to learn something completely foreign to me. It is amazingly fun to be able to make a light blink! Thank you Paul McWhorter!

[@mikehenry9672]

Damn I did the same thing and bought the same exact kit for my summer break from college. I’m going for electrical technician

[@ALIENMACHINES]

What a great teacher!, I mean he doesnt talk a million miles an hour, explains and explains some more and really gets you interested, I never thought Arduino could be so much fun!

[@awkward_bomb]

Wow this lecture just like on a fundamental level really was impressive. I have more experience with computer science than I do with micro controllers, and your presentation of basic principles like variable types, self referencing variable names, and the importance of camel case and case sensitivity by actually demonstrating common pitfalls is great for someone who is completely new.

[@eleftheriasalpighidis6826]

And I thought I finished school at 17, oh, it's so good to be back at school. Your a legend Paul. Back at school at the age of 59. Never to old to learn. Thanking You gratefully.

[@paulmcwhorter]

Legend!

[@spencerg7967]

You are the man! Just started tonight and this is awesome! Thanks for the great videos! Somebody might have said this before, but to help out with the spacing of flashes in Morse there are a few rules. Dits are 1 unit. Dahs are 3 units. The "off time" or space between dits and dahs is 1 unit. The space between letters/characters is 3 units. The space between words is 7 units. For a repeated code of S.O.S you would just pick a unit of time and use the Morse Code rules. Make sure to make the last "Low" delay 7 units of whatever time you are using to make the space between repeated words of S.O.S. I put my "int"s below for R, W, and B LEDs as well as the time intervals for dits, dahs, and spaces as an example. Hope this helps! int R=13; int W=12; int B=8; int dit=250; int dah=750; int spacedd=250; int spacechar=750; int spaceword=1750;

[@dbower58]

I should have read the comments before I came up with the same exact thing 😀 73 de W2GT

[@DaedalusYoung]

Even better if you declare a variable for just the unit, and build the other variables on that. If you want to change the unit length, you now have to change every single one, where otherwise, you only need to change the one. Something like this: int unit = 250; int pulseShort = unit * 1; int pulseLong = unit * 3; int spacedd = unit * 1; int spacechar = unit * 3; int spaceword = unit * 7;

[@hughvanzyl549]

Hi Paul. I am now 62 and sooo excited to find your youtube videos. Just bought the kit yesterday. You are a fantastic teacher. Thankyou for your videos. Soo amazing. I will be building everything as i go along. Know programming from mainframe years but this is so awesome. Awesome gift to a youngster just playing games. Get so frustrated with people that dont learn how to do things. Keep up the awesome job. God bless you for doing this for us. Blessed day. Cape Town South Africa.

[@danthemancasey]

Excellent example of one use for variables! Thank you for another great video!

[@tegolley]

True

[@josephjackson1567]

I have a lot of experience with PLC programming and decided to get into arduino for building small projects and a hobby. im mighty impressed by the versatility of it and the ease of the syntax. keep up the good work and continue drinking your coffee.

[@andrewd4906]

Many thanks for making an easy to follow series on the arduino. Managed the homework. Thanks to your explanation the bits of the puzzle are starting to fall into place.

[@nicholassummerlee6843]

Had iced coffee this morning, but with almond milk creamer and stevia. Also I achieved this by changing the delays instead of adding more code. This guy is the best teacher for circuitry on youtube.

[@MrMoose233]

14:42 Tip to save some time: You can also use ctrl+f to find and replace all instances of the number with the variable. Then you can just scan your code to ensure the replacements were all correct and then run your code

[@antonalderliesten1421]

so in the variable definitions at the top i highlight the "dah" for an example and then press cntrl F and then it highlights all the "dahs" and then what? i see they are all highlighted but a search bar comes up and cant seem to change them to my new variable definition...am i missing something?

[@omsingharjit]

24:40 will 3 separate RGB led work with arduino at same time ?

[@2006death2006]

learning step by step this way is one of the best i have with your codeing help so far made a police car led light flashing with leds blue and red i will share my code here might not be the best but i only been doing this for 30 mins int RedLed=13; int BlueLed=12; int flash=50; int timeoff=2000; void setup() { // put your setup code here, to run once: pinMode(13,OUTPUT); pinMode(12,OUTPUT); } void loop() { // put your main code here, to run repeatedly: digitalWrite(RedLed,HIGH); delay(flash); digitalWrite(RedLed,LOW); delay(flash); digitalWrite(BlueLed,HIGH); delay(flash); digitalWrite(BlueLed,LOW); delay(flash); digitalWrite(RedLed,HIGH); delay(flash); digitalWrite(RedLed,LOW); delay(flash); digitalWrite(BlueLed,HIGH); delay(flash); digitalWrite(BlueLed,LOW); delay(flash); digitalWrite(RedLed,HIGH); delay(flash); digitalWrite(RedLed,LOW); delay(flash); digitalWrite(BlueLed,HIGH); delay(flash); digitalWrite(BlueLed,LOW); delay(flash); delay(timeoff); }

[@Enginmann]

great ,keep going

[@gabrielceolato2]

Im a programmer and now going into arduino, checkout how to do ``C ++ FOR LOOP`` so your code will be much more cleaner

[@imho2278]

Is that with the same wiring setup?

[@tonyflow6244]

in case anyone reads Vapor Wave's response and wonders how to implement the for loop I'll leave a sample here // LED pin numbers int redPin = 8; int bluePin = 6; int greenPin = 4; // delay times(ms) int longDelay = 500; int medDelay = 300; int shortDelay = 100; void setup() { // put your setup code here, to run once: pinMode(redPin,OUTPUT); pinMode(bluePin,OUTPUT); pinMode(greenPin,OUTPUT); } void loop() { // put your main code here, to run repeatedly: // loop red 3 times with longDelay for(int i = 0; i < 3; i++) { digitalWrite(redPin,HIGH); delay(longDelay); digitalWrite(redPin,LOW); delay(longDelay); } // loop blue 5 times with medDelay for(int i = 0; i < 5; i++) { digitalWrite(bluePin,HIGH); delay(medDelay); digitalWrite(bluePin,LOW); delay(medDelay); } // loop green 8 times with shortDelay for(int i = 0; i < 8; i++) { digitalWrite(greenPin,HIGH); delay(shortDelay); digitalWrite(greenPin,LOW); delay(shortDelay); } }

Once again, EXTREMELY helpful. I am managing to trace out faults in the code... after 4 lessons! The sign of a great teacher. Thank you again

[@jassimjaved3309]

Very nice tutorials ! Thank you so much for making these! One feature my friend told me is that if we want to replace any word which is being repeated many times we can select that word and press ctr+f then we can replace that word anywhere it appears. Just a very nice tip I've learned. Keep up the amazing content!

[@imho2278]

Yes, saves me from typing everything as a word doc and then using find!!!

[@pfv3462]

What a great teacher!, one important thing is to put a good description in the code, so someone else can fix a bug faster! I also think it's very special that you give assignments on what you have just learned!

im in my 3rd year in computer science and im having difficulties in learning or understanding the programming languages, the logic. but when i got here... i dont want to leave my laptop and im craving to learn more because u make it easy for me to understand things im having trouble with! You're the best grand dad!

[@Richardj410]

Got my kit and I'm moving along. Thanks for all your hard work and it is helping me.

[@RobVollmar]

Paul, Eleanor and I successfully completed our homework. We made two minor errors in our code, misplacing the closing curly bracket and a semi-colon at the end of one of our delays, but we corrected them. We also added in a fourth delay variable for the transition from one LED to the next, which we think made the final product a little nicer. Using variables instead of numbers in the loop code makes a huge difference in being able to make adjustments to our program. Thank you for being such a patient and fun teacher!

[@paulmcwhorter]

And how special your daughter must feel that you spend such time with her. This is so valuable yet so rare these days. Your daughter is truly blessed to have a father that spends time with her.

[@RobVollmar]

@@paulmcwhorter That's very generous of you to say. I was just thinking yesterday about how quickly these first six years have gone by and, in the same amount of time, she'll probably be turning to me a lot less for care and company. We only have so long to be the most important person in their life. My dad wasn't around for me as a kid so I'm trying to make the most of the time we have.

One thing I like about these tutorials is i'm also learning how to code and coding with a purpose. I watched several python tutorials but I did not see a purpose of the code i'm learning. This tutorial is not only teaching you how to code but also giving the code a purpose which is towards the arduino computer.

Hello Paul I wrote integers like that: int redLED=4; int greenLED=8; int blueLED=13; float pi=3.14; int redBlink1=250; int redBlink2=700; int greenBlink1=500; int greenBlink2=900; int blueBlink1=750; int blueBlink2=1100; int longW=2000; and it worked for me. In void setup three pinMode for each pin and in void loop repeated three times changing the variables only. Thank you for your teaching.

[@juney3666]

This is the first tech teacher and I think I don't need to take online classes on this.

[@Reckonart]

I live in a country where public schools don't have the resources to teach us Arduino or any form of useful programming. Books to learn tech aren't available here, and e-books are too expensive for me. I felt discouraged for a long time thinking i would never have the resources to learn and apply to a competitive university with the same skill sets as kids in better countries. This course helped me understand the basic things to propel me into making a project for my exams, and earn excellent grades. It also exposed kids of lower grades in my school to microcontrollers and encouraged them to learn it as well. We hope to make a big collaborative project and hopefully get the attention of the ministry of education for funding and reforms. Thank you so much for this comprehensive and generously free course, sir.

[@paulmcwhorter]

Angela, thank you for the kind words and encouraging comment. Really glad to hear these lessons are helping people. God bless.

[@richardstewart4135]

As a ham radio operator, I got a bit of a chuckle out of this particular lesson. I had kept my homework lesson from the previous lesson in place through this one, and it made this one rather easy. Looking forward to the next lesson.

I have been following over 30+ of your Arduino classes now during the quarantine, relearning a lot of stuff I forgot, so on this day I would like to say THANK YOU and wish you a HAPPY TEACHERS DAY!

[@souljr.]

Again with another absolute banger of a lesson! I never would have thought to do Morse Code experiments with an LED! Lots of fun, and loved learning how to declare and use variables! Massive time saver for changing the parameters of the whole program. Using what I learned through the last lesson and reading comments talking about how better to optimize the program, I was able to get the homework for this lesson to run with only 53 lines of code!! There was some referring back to my notes I've been taking, but I did it mostly off of memory!

I always love when you say something like "DelayTime is equal to 500... NO NO NO, use variables!" That really helps me remember too... "Use Variables"! ;) Thanks Paul!

[@Turtlehands]

250, 500 works ok too for Morse code.. And I used 250, 500, 1000 for the homework. There's nothing like typing it in, and then using find/replace. Huge time saver! You get some errors(at least I did), but it saves time. This course is GREAT! Keep up the excellent lessons!

Hey Paul! Your videos are great and very helpful for a beginning Arduinist like myself. These are the most helpful, straight forward Arduino instruction videos I have seen so far. I am fluent in other programming languages, so I was able to answer all the questions that you were asking the audience. I hope you heard me. Anyway, I was watching this video and kept asking myself if it's possible to create functions in Arduino (I looked it up, and sure enough you can). This might be a helpful topic to cover for the sake of others and would go along the same lines of this video here. Thanks so much for these videos!

[@collectorsinfo]

Just what i needed & is really helping. Would be real nice to have some video's on some viewers projects & requests on items they are trying to make, but cant quite make it work & you step in to help & suggest a better alternative. Fault finding is a great teacher. Depending on costs, i would happily pay for this & hope myself & others would appreciate even more lesson. Loving it so far. Keep it up.

[@roberthead127]

Watching for the fourth time, I know how important the fundamentals are. Most of my problems come from incorrect usage of the keyboard, maybe a few episodes on keyboard use, and relevant shortcuts. It would be especially good for the elderly student like myself who don`t know how to use the keyboard properly.Rob xx
