Arduino Workshop - Chapter Three - FOR Loops

The full Arduino Workshop in step-by-step format can be found here core-electronics.com.au/tutor...
In this section, you'll look at 'for' loops which you can use to control the flow of your program.

I’ve just discovered your channel and really like it, good job.

[@RajaSingh-hs2tb]

You explained very well

[@salc9593]

Thank you for posting this video, it has been a great help in my learning of Arduino coding. I would like to ask if I wanted to have this LED ramp 5 times would I add the first part of the code you show at min: 0:20 around the ramp code by using curly bracket? Thank you again for posting these videos.

[@attalaw36]

nice lesson thank you ...

[@waluxstudio7921]

Thanks for explanation. I like it

[@whitefields5595]

As you only want to count 0-255 would you save memory if you defined i as a BYTE datatype rather than an INT?

[@puvaneswaransivakumar9469]

Can I know how to loop forever the melody example in arduino??

[@johnnagy1575]

I don't want to ramp up and down. Just want to blink the led 5 times. Stop. And wait for a Button push again. Any videos on that??

[@jean_pattat1204]

i had troble with this so i watched other videos and i found the error you must be plugged in with a digital pwd most bords have these and are marked with a ~

[@geneh9210]

What does the statement "for(;;);" do? I've seen it in a couple of example sketches. Thanks.

[@nuwanchathuranga8479]

thanks a lot.....

[@tareksma1]

Thanks for sharing. I finally understood the for loop. Now I kinda feel dump for not being able to understand it sooner 🙃 😕

[@Chriss.lindstrom]

How do I make the code jump out of the 'for' loop? As soon as it counts to 5 for me, it starts over at 0 and jumps straight back into the loop. I want the value of x to stay at 5 until I press a button.

[@d3bbi339]

i believe you would add
break;
inside of the "for" loop. but im just referencing his previous video about "while" loops so i might not be correct. lol

[@Perdonadoooooo]

In case someone else's LED only ramps down and not up, write "for(int i=0; i < 256; i++)" instead of the first _for_ shown in the video. Mine behaved like so and with that correction it now works properly. I'm guessing "int i" doesn´t declare AND set the variable to 0, so that's why it only ramped down. Someone correct me if im wrong

[@jeffturtle3565]

Yeah I'm pretty sure you're right. He had a typo for sure.

[@infatum9]

I think they chose i for for loops because it stands for iterations.

[@Sedokun]

It stands for 𝑖, 𝑗 indexing Index Notation in math. [Aᵢ ⱼ] where 𝑖 - index, 𝑗 - is just the next letter for labeling the next dimension (then goes 𝑘, 𝑙, 𝑚, 𝑛 ...)

[@timwhite7127]

Nice. fyi, 'i' is used for convention in loops to indicate "iterations".

[@-stoner]

I'm trying to make a game where LED's blink back and forth and when you press a button it stops on the LED it's on and gives a certain point value for each LED but the for loop keeps iterating and blinking the LEDs

[@viktortousseyn7698]

How do you do 7 led lampjes burning

[@omtandon2741]

I searched this on youtube for the same thing!!!

[@scopellafranqui]

I've had to change "int i" for "int i = 0" in my first for loop otherwise each loop starts with i having a value of 255. i.e. if I don't add "int i = 0" the LED starts each loop at max brightness then fades instead of ramping up then fading.

[@vinothparker7425]

i'm also facing the same issue right now. i want to know the reason why this is happening like sir. can you help me?

[@vinothparker7425]

void setup()
{
Serial.begin(9600);
}
void loop()
{
int i;
for(i; i

[@mr.m_photographs]

Same thing happened to me. This fixed it.

[@robertaragon8270]

same

[@PAWNB3YOND]

I love you.

[@danieljohnsopardenilla997]

So a 'for' is like a sub loop?

[@Sedokun]

It is. And this is why this code is "blocking" it halts the Loop until For is finished.

[@firealarmswithcolton5169]

my brother told me i need a for loop for a buzzer tone sequence on an if but this video made no sense to me.

[@vinothparker7425]

void setup()
{
Serial.begin(9600);
}
void loop()
{
int i;
for(i; i

[@Core-Electronics]

tricky ! If you can, please post this to our forum coreelec.io/forum - our team can provide better support for coding issues there.

[@pranilshoots9523]

Its becaude the ASCII equivalent of 0is 52. You need to convert it to integer to see correctly in serial monitor

[@ryanbennett8434]

If this doesn't work for you then make sure you are using the digital pins (NOT analog).
