Arduino Tutorial 16: Fun With Arduino For Loops

You guys can help me out over at Patreon, and that will keep this high quality content coming:

In this video lesson we look more at the Arduino For Loop. We will give you examples that allow you to better understand the three parameters used in the for loop.

You can get the following Elegoo kit, to follow these lessons and play along at home

You can also follow these lessons on our WEB site:

Retired engineer. Really enjoy your enthusiasm and frequent deliberate coding errors. Keeps your students alert.

This tutorials series is absolutely invaluable. Looking forward to finishing this series and then starting with the next one. This is what all education should look like!

I always pause the video when you say, "I want you to..." or "What if we wanted x to do y?" and try to do it myself first before proceeding. I think it's helpful to have practice finding my own mistakes. Plus, when you "make a mistake" (quotations because I'm sure most are on purpose to keep us on our toes!) I don't end up copying it into my own code. I'm glad you have a lot of videos here because I plan to watch every single one and do all the exercises so I get lots of practice. Your videos give me hope that soon I'll be able to manipulate LEDs in my work as easily as the wire I weave with. This series is truly an invaluable resource!

I am 69 retired Draughtsman from South Africa. I was given an Arduino Kit for Xmas and I am having fun learning about coding, keeps the old brain active. Thank you sir.

I was able to figure out the different counts on my own. These pop quizzes are helping with my coding confidence.

[JungleCruiseSkipper]

I figured it out right off the bat, but I still ran out of the room crying like a little child... they were tears of joy!

This toturial is AMAZING. Its very effective, special the "BOOOM".

[jackmccarty]

One of the things I appreciate the most is having these videos to where I can pause or re-run. At 82 years old, trying to learn something totally new takes a lot more time then I'd have were I in a classroom. I can go over and over the material until I think I really understand it all. Great job Paul. Loving the clarity of your presentations. See, even at 82 one can still learn in the right environment.

Figured out the countdown in about 20 seconds, before you asked. Wish I had you as a teacher when I was in highschool

[jimmitoraj]

I am a 61 year old carpenter starting arduino as a retirement hobby. I want to thank you for your tutorials you do a great job explaining them. The only computer skills I had was using my smart phone and I am still able to figure it out. Keep up the good work.

11:36 This is what I was always expecting when you hitting the table like that and It happened😂.Thanks for your another interesting lesson sir.

[ZeroQ]

11:21 I use an if statement in it and make it return then it reaches j = 1

int j;
int delayTime = 500 ;

void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
}

void loop() {
// put your main code here, to run repeatedly:
for (j = 10;j <= 10; j = j - 1) {
Serial.println(j);
delay(delayTime);

if (j == 1){
return;
}
}
Serial.println(" ");
}

Figured it out without having to pause! Trying to catch up Paul!

[TheSparrow]

Dropped out of engineering after my freshman year, spent the next 42 years working Avionics on military and commercial aircraft. I'm now back to engineering classes as an old guy and loving it! Love your teaching style!

[charlietrain]

when programming now I catch myself saying "NO NO don't use a constant set a variable"

[kirstinlee]

I really enjoy your videos and the small conversations you hold throughout. I was able to get the numbers to count backwards without folding like a card table.

[zennihilator]

Here's some tips for the peeps when it comes to 'incrementation' in C++:

instead of writing j = j + 1, you can write j += 1, OR j++

All of those commands do the same thing, increment your integer by ONE. Note that if you want to increment by more than one, you can no longer use the ++ command, that's only reserved for incrementing by factor of one. If you want to increment by 2, you can use j += 2 etc.

Same goes for negatives: j = j - 1 is the same as j -= 1 and the same as j-- (two minus symbols)... If you want to increment by negative two, you can write j -=2 etc.

I was able to figure it out!
You are not talking to an empty room, you are a great instructor and I appreciate your lessons.

[BrickBrick]

absolutely love the consistency of this series

[DougBatchko-oiot]

I figured out how to count backwards on my own. I really appreciate your videos and how you teach. I'm older (mid-40's) and going back to school for engineering. Your videos are required for our Systems Engineering class and your videos are easy to follow and very informative!
