Arduino Tutorials: Control a LED with a Button

[@francescomendola]

int ButtonValue = 0; int Button = 3; int LED = 2; void setup(){ pinMode(Button, INPUT); pinMode(LED, OUTPUT); } void loop(){ ButtonValue = digitalRead(Button); if(ButtonValue != 0){ digitalWrite(LED, HIGH); }else{ digitalWrite(LED, LOW); } }

thanks bro

[@domonkosimrik8051]

Thx man this works well

[@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.

[@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

[@MarkSMays]

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

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!

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!

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!

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🙂

[@johnslick8940]

you are definetly not a smart one lol

[@thepanda3757]

the music is not helping to focus

[@chanakyashukla5820]

firstly it is never called "le'-ed" it is an abbreviation and is always pronounced as L.E.D. (light-emitting diode), so never call it again "Le-d" because it is something else. Lead is an element with the scientific name Plumbum and symbol "Pb"; Atomic number: 82 Atomic weight: 207.19 Diodes are semiconductors not metal like the lead. Secondly, using a push switch to turn on or off the LED is so lame. I mean what else is the purpose of a "push switch" or be it any switch that exists. The switch simply cuts or completes the circuit. You can simply power 5V or 3V to an LED and if you add a switch to the circuit it will glow when pushed and will turn off when not pushed. What is the point of using a microcontroller then where is the automation? There should be at least different patterns of LED turning on or off when the button is pushed. make something challenging and use proper scientific language else a little confusion can create blunder mistakes.

[@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

[@ThatOneRobloxDev]

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

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?

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.

[@anokhautomation4453]

The LED must stay ON even you release the button. Then the second press,LED should go OFF.

Why in blazes do people who post instruction videos feel the need for all that stupid distratiing music. Lose the music then we can consentrate on what you're saying. Imagine the Almigjty God giving Moses the 10 Commandments with ACDC or the STONES blaring in the background.

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?

i dont even have any pullup / pull down resistors, i do have normal resistors from 10 resistance to 5 million tho

Good video. By the way, it's "an LED," pronounced "an el ee dee." LED is an initialism, read aloud as three separate letters.

[@krishaykondapalli9693]

My issue is that I have an attachable power supply rather than an arduino board. Could you still use the attachable power supply?

[@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.

[@Alex-fk2ie]

I wonder that i've read some code and they said differntly about the LOW HIGH state of the button.Some said that when we pressed , the state of the button == LOW, some said the opposite.Can you explain it clearly :'(

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.
