Arduino digitalRead Serial Monitor with Button

Arduino Basic Tutorial digitalRead Serial Monitor with Button. Reads a digital input on pin 2, prints the result to the serial monitor.
When the pushbutton is open (unpressed) there is no connection between the two legs of the pushbutton, so the pin is connected to ground (through the pull-down resistor) and reads as LOW, or 0.
When the button is closed (pressed), it makes a connection between its two legs, connecting the pin to 5 volts, so that the pin reads as HIGH, or 1.

Friend, thank you very much. This video of yours has saved me the semester in school, it has saved me from a fight with classmates and I may even get a girlfriend. You're the best. You have a new subscriber and lifelong admirer.

Bütün gün aradım buldum sende oldugunu daha yeni görüyorum bundan sonra ilk sana bakacağım 😂 ( internette çok karmaşıkları var ve dataylı anlatım yok tebrikler )

[@abhijaypratapsinghtanwar9242]

Great video man total rocking I was inspired by this video dude!!!!!

[@abdelrahmanellithy6499]

I have a question to ask, please How does the pin(2) attached to the third leg realizes that the two legs of the push button are connected when the button is pressed ?!! in another form: How does the 4-legs are connected to each others ? thank you

nice guitar playing

Connections: Switch: left side vertical pins (1 & 2). Connect pin 1 to 5v, pin 2 no connect. Switch: right side vertical pins (3 & 4). Connect pin 3 to R1 (10K). Connect R1's other end to Gnd Connect switch pin 4 to Arduino pin 2 /*Digital Read with Button: Upload sketch then open Serial Monitor (9600): a "0" will appear on each update. If the button is pushed a "1 will appear on each update until the button is released. Close the Serial Monitor & open the Serial Plotter (Tools, Serial Plotter). A trace line will appear indicating "0" level. Push & hold the button. The trace line will now indicate "1" until the button is released */ int pushButton = 2; void setup () { Serial.begin (9600); pinMode (pushButton, INPUT); } void loop () { int buttonState = digitalRead (pushButton); //read input pin Serial.println (buttonState); // print state of button delay (1); }

i LoVe your videos.. & the music u used

[@pccxp]

Hi, I started doing the same on my Arduino, But I'm trying to read if the LED is ON (1) or OFF (2), But i cant make it work :(

how to serial monitor two button? press button 1- monitor 1, if press button 2- monitor 2...

[@taranagnew436]

can you do the same code but with a LCD shield and have the serial monitor read the buttons on a LCD shield?

[@silentsniper9531]

My curve looks very different, unfortunately. When I don't touch it, it draws something similar do a sin-wave. When I press the button, the amplitude is zero. Where did I do something wrong?

[@teamzawafootball1370]

I have the same result, still don't know why

[@chirayuagrawal3317]

Thanks for your help!!

[@qzorn4440]

sweet video, would this be good to test the esp32 port serial2 with a rs485 ttl module? 😊 thank you

[@mightydead7151]

sir why are you add 10k ohm resister with button to ground reply please i want to know

[@Arthurk346]

i tried once grounding 5v directly to GND without resistor and arduino rebooted right when i pressed the button (i guess safety feature). hopefully it survived but i dont want to repeat the process again haha

[@coringavinte5105]

perfect video

[@ahmetberakarasoy2553]

Kralsın allah razı olsun kaç saattir bunu ariyom

[@suloman5845]

merhabalar hocam.bir projem için sizden yardım isticem. motosikletim için arduino üzerine kurulu bir ekran projesi yaptım sonlandırdım ancak button eklemem lazım su geçirmez falan olsun istiyorum aliexpresste görebildiğim kadarıyla on/off durumlu buttonlar var bu arduinoda kulllandığımız gibi çıtçıtlı digital veri alabildiğimiz buttonlardan yok. sizce nasıl bir yol izlemeliyim?

[@engjawad8645]

It is so difficult for those watching ur vedio through the mobile to see the code .

[@rjnmex]

Thanks!!

[@kartiksingh9382]

kindly don't forget the esp8266 robo

[@gijsvanderburgh1556]

Thanks

[@Unkn0wnTimes]

why did you use 10K ohm? reason?

[@matiasfurnes4834]

If you dont, you shorting the Adiono board beween the pluss and minus terminal. And that is bad for the Arduino board.

i wanna get circuit please give me them.

[@saseeka-weerasinghe]

tnx bro

[@bob-ny6kn]

One minute to put a button on a board? F*
