Turn up to 1.75 play back speed if you wanna get moving, leave it as is if you want something soothing ;)

I found this series so clearly explained, with clear, relatable metaphors. Thank you :)

[MrRadbadger]

Your shining LED thumbnail is very appropriate. This video was a light bulb moment for me. Excellent work💎👌

[houalee]

So to summarize --
setup() function sets up the environment for the loop() function (what's going to be used for inputs and outputs, and such...)
loop() functions loops through the code over and over, and sends out instructions to inputs/outputs as instructed (or conditioned).

Hey thanks for the video. I've seen other code that have more than just one loop function on it, could you explain that in another video? again, thank you.

A holy grail video absolutely a core tool

[samup]

This tutorial made me hungry because of the analogy! 😂

[amalelghailani]

Thank you very much for this simple and clear explanation :) please keep going on your intresting coding videos <3

I wish the crash course didn't stop

[hamzaettaleb]

Very good and clear video. Thanks you.

[sherlanmamaril]

Awesome on how he relates coding to real life

[pakistantechnology]

veeery simple veery beautifull, perfect way to explain. thank a loooot

[dejavu]

Nice analogies - thank you for this wonderful series. You explain everything so well.

[tnarch]

Helpful explanation, thx for sharing.

[wilcornejo]

Love your tutorials thank's for your time.

[HyperionBadger]

This is actually a really good video. Thank you.

What if I want to build an array of 10 numbers using a "for loop" when the program begins, but do it only once? Can that be done in setup? Can the array values then be used in "void loop()?"

[adrianTNT]

I am confused about something ... How is setup() different than just writing that code above it (after includes) ? That should also run just once. If so, why the need for setup() ? And can setup() be called again to reset things ? If so, did I just answer my own question ? :)

[taranagnew]

could I do a void setup and not have a void loop if so , how?
