Functions won’t eat arrays whole - Do this simple thing instead!

[@robertobrenes5283]

This channel is one of those gemstones you find on the internet, thank you for your great work!

[@programmingelectronics]

Thank you Roberto!

[@naboulsikhalid7763]

Grateful you add this topic to Arduino tutorials, but I found it very important when dealing with multiple identical elements and you want to apply the function to those elements. thank you

[@programmingelectronics]

Thanks for watching!

[@ediekimo9110]

Man! I love how you explain the concepts. All of the sudden a confusing idea becomes so familiar

[@programmingelectronics]

Thanks Edie - I hope these are helping!

I was trying to pass an int array from function to function but could not get it to work, the end result would be random numbers. I guess it’s because once that function is executed, the values are erased. Is there a way to do this without initialization a global array variable?

[@icarossavvides2641]

Watch the video again, it's explained quite clearly. You cannot pass anything from one function to another because they are different Scopes, Once you exit a function all the local variables disappear. Whats your problem with global arrays, I wonder?

Excellent, simply put.

Glad you liked it Flashback!

what is the difference between your youtube lessons and your accadamy course?

[@programmingelectronics]

Great question! Our academy has in-depth structured courses as well as a private forum. If you like our KZbin channel content, thank you would enjoy our training program.

I have just started working with Arduino a few weeks ago. I'm using buttons and the Adafruit NeoPixel library to set a certain pixel to a certain color. This is working, but obviously when I reset the Arduino, the pixels reset as well. I am trying to use micro SD card to store the specific pixels and the color I've set them to. But I can't figure out how to store the info and then read it back, so that when the Arduino starts up, the pixels light up with the correct color. I need to be able to set pixels one at a time, to red, green, or blue. Any help would be greatly appreciated.

Super appreciate these great tutorials. Got a question: Since the BUFFER array is being used to store the multiplication results does this imply that the two original arrays are left intact?

[@programmingelectronics]

Great question Frank! You are correct.

"Yay, functions will make my code cleaner." *tries to return an array in his first function* "malloc(), free(), pointers, return by reference... well, this is BS..." I just wanted to have a few elements neatly sorted in an array. Everything works fine with no stinky functions. Idk what's so problematic about arrays like holy fck... they might weight a bit more, but that's it. If they work everywhere but in functions, then what's the point of using those? I hope this wonderful video will fix this without wasting precious memory that people on the forums were freaking about. EDIT: Hmm... so basically, since memory-wise arrays don't store their elements, but rather pointers to those elements, we can just forget about sending an array out of a function, because the manipulations we do, we do on the actual original elements themselfes, so everything is "already sent" so to speak. (It's as if instead of writing a letter to somebody, we write in their diary. lol) Thanks a lot, man, finally got it.

May I request people learn to write more clearly and moderate their language please?

array funtions?

Thanks executive! Updated

@@programmingelectronics Hey I am really glad that you're making these programming concept videos on Arduino. Just want to let you know, you're making a lot more of positive impact than you may notice. I learned programming using Arduino, not the best path but was stuck in there but I am really happy that you helped me get out. Keep up the great work!

@@programmingelectronics hi sir informative video on arrays concept . Can you pls do a video on how to return function pointer . And how to use understand the usage typedef with function pointer .

[@programmingelectronics]

Thanks so much @yashaswi! It means a lot!

[@programmingelectronics]

I'll see what we can do - thanks so much for the recommendation!
