Arduino Interrupts Button Tutorial Example - Pin 2 Hardware Easy Guide

Arduino Interrupts are powerful. In this tutorial, I will be showcasing an example on how to tie Pin 2 of the Arduino to a hardware interrupt with the use of a button. This simple guide illustrates the functions of an interrupt, how it triggers different software states as well as the configurations you need to make.

We will also take a deeper dive into the intricacies of interrupts, where they may be needed and how the configuration works in the software.

Dear viewers, I'd like to hear back from you about the next topics for my videos! I've re-vamped my list of things to cover. What kind of projects are you currently working on? Where are you having the most trouble? What do you believe I should cover?

It would mean the world to me to hear your feedback!

Cheers,
Vlad

Vlad, this is the best in-dept interrupt video on YT. Just the right time and thoroughly explained. For me, so good to see that you are still doing Arduino tutorials. I think you are a born teacher. Thanks for posting.

Thank you for this super useful video which is particular relevant to a project I am working on where when ever random data occurs it should wake up up a processor record that an event has happened & then go back to sleep. I was particular taken by how well the interrupt works in the little robotic car that you showed, much more demanding than my particular project giving me confidence that I can get satisfactory performance. Thank you for sharing!

The way you explain everthing, its awesome... please also make video on SPI communication but without library using... we need to see the communication.. thanks

First of all congratulations: you are e very good teacher. Even if I am italian I can understan almost everything (and I am sure I will understand everything when I will see the video again).
I would like to learn in depth how to control motors (not stepper or servo, but simply motor) with Arduino Uno or Arduino Nano (power shields, wirings, sketches). Thank you.

[gabrielcross]

this is very helpful. How would I do the opposite? I want to set the interrupt so that it is always stopping the program, then pressing the button will allow the program to run.

As you said using interrupt, something can be nightmare
In ISR, I am Switching OFF a 220V 5RPM motor in ISR . interrupt trigger on FALLING edge through a npn proximity sensor.
Motor is connected to a RELAY.
Software part is switching ON motor after every two minutes.

I found random behavior, something motor gets ON after 2 minutes, something its not.
May be interrupt is triggering due to RELAY EMI/NOISE ?

What is the safe way to use interrupt ?

Hi sir, I am getting this error, what might be the problem, thanks

'InterruptFunction' was not declared in this scope

Could you also make a video on programming stm32 m4 cortex or any arm processor and also highlight the differences between arduino and arm and their uses. Thanks!

I made an ultrasonic height and weight measuring device. I wrote the codes with Arduino and arduino UNO. Normally everything works fine. But sometimes after waiting for an hour or two, I take a measurement, the device is measuring, it shows the numbers on the screen, but it does not print the result to the thermal printer. The numbers stay on the screen, then the device is reset with whatchdog. This is starting to get annoying. can you help me with this

[aimansam]

hello sir, what if make the led wont stop working after button pressed?

[artemmelnyk]

Thank you for your video. Is it possible to use both pins (pin 3 and pin 2) to call two different ISR ?

[SK-wety]

thinx ... it is very useful
but i have a question about MPU 6050, i used your code (that you provided in previous video ) .... but i failed to get rotation angle about Z- axis.
is that possible by MPU 6050 or should i use MPU 9265

[eduardocastillo]

Thanks for your video (y), you are magazine.
I have a question, when you push the button, the funtion "interrumpFuntion" should do and turn the leds on but when you push the button, all the LEDs are on, why?

[LemonTreeNOTfree]

Because I do not have experience in it. The function "while" as similar as interrupt.
Nevertheless if this exist, this of course practical.
