Arduino Tutorials: Control a LED with a Button

[@glebdubs]

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 KZbinrs miss out is amazing, and that's what saved me hours of work! THANK YOU!

[@pimentomori259]

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

[@Ali_Alhakeem]

Ok this was really helpful , figured out i didn't use resistor and it works now thank you !

[@catacutanroselynb.5632]

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

[@electronix6898]

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.

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!

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.

[@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!

[@patstarks]

It looks like there is an extra wire in the animation. Nevertheless, I was still able to follow along and get the LED to light up! Great Content!

[@HamzaKhan-bg9fh]

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.

[@cccp9661]

Agree

[@rinopro5556]

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

[@MarkSMays]

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

i appreciate the graphics and the explanations!

thanks bro

[@domonkosimrik8051]

Thx man this works well

[@bullet_7717]

Really nice! But i have a question, if i want to do the opposit? Namely, with the button not pressed the led must be on, with the button pressed led must be off. In other words, I would like the button to be as normally closed.

[@kmhooibg7577]

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 resistors should I use?

[@virathiyam5401]

Well done my bro.. liked & supported.. I want to ask.. what is the technical name of the 4 leg switch when you push once-led glows dim, push twice-led glows bright, push thrice-led shuts off? The push button on my led lamp stopped woking and I need the name to search and order it in Amazon. I'm not an electrical engeneer so I don't know the name.. plz help out.

[@Hektowa]

If my button is a little too big can I use a connector to do it?

[@x-x1329]

Thanks. I would like to know how many ohms of the resistor 3:19.

220ohm

i tested it with a Leonardo and a (3rd party ELEGOO) uno rev3, it works both ways, the leonardo is the original, its cpu is all rusted a bit, i think it's from 2013 or 2014, and its a leonardo, made in italy

guys be careful when you plug in your 5v and gnd pins cause ive been trying to do this for 2 hours and i relised i didnt plug the 5v and gnd pins to the breadboard🙂

I challenge you, make it so if you click it, it blinks multiple times, or when u click it, it stays on for 3 secs, OR even HARDER, make it fade when u click and stop fading when u release

Next Time can you please give a link for the code

[@Dasgath]

the diagram and the connection you did are different. Switched ground and pin in the connection for the led... and still works?

[@Dasgath]

Anyways eems like it doesnt matter where you put the resistor, since it is in series it shares the load with the led. Thanks for the tutorial, finally managed to make mine work, i had a bad wire and spent 2 hours trying to figure out what the fuck was going on. Guess i need to learn how to do the serial monitor.

[@omarrashads7888]

Can i get the b design simulation program?

[@deva8496]

how does your board do nothing when you are connected to pc? my aurdiono keeps running old code that is uploaded. what is the trick here?

[@freethepotato]

Well, probably I had a blank or default Arduino project running. But the behavior you described is expected. The current Arduino code starts running when you power it on.

[@RiyaSharma-wn2nc]

Will it work if we remove the Arduino cable?

[@ScitiveX]

Yes but you'll to provide external power.

[@fergspan5727]

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

Wow, that's actually awesome. I've always wanted to participate in something related to that. There's a lot of things you can apply like telemetry, remote control, wireless comunication, etc. If you need help with something just say the word!

[@finn3721]

Nice, its working :))

[@soumyajit5202]

Hey how do you choose the resistors???? I mean according to which context is it LED?

[@freethepotato]

Hey! The resistor is there because if not, there would be a short circuit due to the led's resistance being so small. For that, any value from 300 to 1k (even more) should do. The thing is that the leds brightness increase with the current so you cannot put a very small resistor (more current, more light) neither a huge resistor ( less current ). When a short circuit happens, the current in your systems increases to infinite and that will burn the led. If you want to learn more about this you should see a tutorial about the ohms law. Check this out (about leds): learn.sparkfun.com/tutorials/light-emitting-diodes-leds
