Arduino Tutorials: Control a LED with a Button

Our second arduino tutorial! Here you can learn more about the INPUT/OUTPUT and how to use it.

Don't forget to check out fritzing! An awesome software that was used in some clips in this video.

A new video will be posted next week on Serial communication! Thanks for watching

You saved a project for which I worked for hours on - thank you so much!
The fact that this video includes EVERY SINGLE LITTLE DETAIL that a lot of Youtubers miss out is amazing, and that's what saved me hours of work!
THANK YOU!

Remarkable Video! Will be showing this to my son who is currently using Embedded Learner Board by Moonshot Jr. Never thought that understanding Arduino and related coding can be made so easy. Thank you for this video.

Thanks for the video. Others I've watched had a different way to wire the button and my LED would come on randomly. Your connections fixed that!

[DarlingbroughModelRailway]

Thank you!
I've been struggling with the if function, but this video has explained it to me in a way I understand!
Subbed!

Thank you so much. This is the easiest and understandable demonstration video here in Youtube.❤

Thank you very very very very very much!
I've been struggling with the button controlling function! But this video has explained it to me in a way I understand!
Liked!

What tool are you using to draw wires between the processor and the breadboard? It’s very nice. Nice demo also.

[robertmarkham]

Very good at explaining things, I've spent the last week trying to write a script and it all fell together then i saw you Showing how it works, Thanks!! Subed!!

[aminebenjalel]

Thank you a lot !! You're saving me I have a project about it and this video is exactly what I searched !!! Thank you !!

[playlistmaster-thebestplay]

what can I say, man, HELPED ME OUT, thanks so much man, I needed to watch this fantastic video so I could control my Piezzo element

[nickjames]

Thanks, its working but I'm confused. Why do we don't need a connection from from anode of LED to +5V?

[pimentomori]

thank you so much, im just starting out with coding and my computer teacher is useless, taught me more here than half the semester has

[salc]

Thank you for posting this video I found it informative. I would like to ask IF the code you wrote can be used to begin a Sketch?

[russellbloomfield-Luck]

The advice about the step down resistor was really helpful

[HamzaKhan-bgfh]

The virtual sketch differs completely from the actual setup you had. Additionally, the virtual sketch does not work, and it is also the one you went by step by step, so people copied it in their own boards and that it why so many people have problems.

You should have at least addressed why the sketch was different from the setup...I spent a while on this video and it ended up not amounting to much.

Mine worked fine. Now, I need to figure out how to put 3 LEDs in there and control them with 3 different buttons. I'm trying to work on a cool little game where I put in a random pattern of 3 flashing LEDs and you have to remember the pattern and press buttons of that pattern. Just a little personal project.

[MAquaJJ]

For me, you have the best arduino tutorials, keep making please

[fergspan]

Now latch it by only when the button is pressed once the light stays on and when pressed again it turns off ?

[firewater]

i appreciate the graphics and the explanations!

[rinopro]

Thank you so much, you explained it in such an easy way!
