Arduino Workshop - Chapter 5 - Interrupts 

(1) Excellent video (2) All information relevant to the subject was covered (3) An example code was provided.

1. Thanks for NOT adding loud music instead Soft && short . The instructions are very good. thanks

You are by far my favorite IT nerd

Game changer! Well explained. Thank you

Very helpful video. Thank you!

Instant sub - great teacher, please don’t change a thing.

Thanks for the video, it was really useful!

Very helpful video. Thanks for sharing.

thanks for your quality video. keep up the work

Respect for your quality work. Great videos. Thank you!

Well done. Clear and comprehensive.

Sweet, thanks! Exactly what I need for a project I'm working on :) Finally understand what I need to do ^^

Thanks for useful information

Great video.. best on using interrupts

Would an interrupt be the best method to have an output to energize a relay every hour.?

great Video thanks

Yes I likes it too. Must be the fourth tut I’ve watched and I reckon this was about the clearest. Better go and do some coding. Thanks

So an interrupt vector is the address of the machine code to run when an interrupt is detected or called. It is not the same as an Interrupt Service Routine, which is the code to be run on the interrupt, but is an address to an Interrupt Service Routine, operating system code running on metal. The interrupt vectors can be put in a table that allows for the updating of the interrupt routine without changing the calling routines code.

Nice explanation. I’m using a Nano that limits me to pins 2 & 3, as you said, but I’ve heard about PCINT that allows you to assign a software interrupt to other sets of pins. This true?

Oh man...a big huge 'Thanks' (and a sub!) for this incredibly informative and well presented Vid. You have been a great help to this Arduino noob!

What seems goofy to me is the loop is going to run all that code for the setup of that interrupt each time around when I could reduce all that with a two line of code button branch loop.. 🤔 ,,but then again in a heavy complex code it might be beneficial as you stated.

Great teacher you are :) insta sub, thank you

Really nice explanation of interrupts

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

Hi i built my own flux capacitor from back to the future, with my friends help. We have written a large sketch with 9 sequences. we have the y centre leds (3 strips of 10) and door leds (4 x3) working simutaneously. we are using arduino mega. everything works fine but we are having the problem of the IR remote changing the sequences. i tried incorporating your code, it uploaded fine but didnt make a real difference. happy to show you the code if you could help. thanks

If I try to use ISR method for measuring the rotation speed of a DC motor with Hall sensor, I can't use PWM control (it's a rotation speed control system). Somehow the PWM signal wich I try to send to the PWM to DC converter is not constant and stops every time I calculate the speed. The interrupt method should be the most precise in measuring rotation speed. Any idea what is the problem?

Good content, thanks your tutorial

How I do interrupt when signal low and interrupt break when signal is come to high

2 things: 1) if you write async code and/or use state machines you don't need to use interrupts 2) on x86-64 you can easily corrupt your own data if you use linux signals which are similar to interrupts, because reads/writes are not atomic and you can get an interrupt in the middle of a variable assignment. not sure if it's the same on arduino

The wisdom within this content is remarkable. A book with akin insights influenced my personal evolution significantly. "A Life Unplugged: Reclaiming Reality in a Digital Age" by Theodore Blaze

Please, if possible, I would like to run several LEDs using a number of swings in the Arduino program

im woking on a project which i use a couple of sensors. i have a problem which i use 2 encoders to messure rotation speed (using interrupts); and i have another IMU sensors (for messuring acceleration). how can i read all the data from all those sensors?? i have a problems which im using interrupts for encoders and by that i cant read the IMU sensor thanks

Thanks

thank you for the video great...if i want to creat a sketch that do something but if the is no changes for 2 sec donc do this sketch do you have an exemple please any one help thanks guys

Thanks again bro. In the workshop page there is a chapter 6 which talk about IOT. But the videos are not related. I wish if u can add the videos. 👍

Thanks!

Is it ok to use more than three interrupt digital pins?

Can the ISR run a function to exit out the loop that was running before the interrupt?

I want to read 8 rotary encoders simultaneously. Each encoder is a quadrature encoder with 2400 counts per revolution. Two interrupt pins are required to read the direction and position of each encoder. In total, I require 16 interrupt pins. But Arduino mega has only 6 interrupt pins. Should I use 2 Arduino mega as a slave and 1 Arduino as Master in I2C communication? Will this alternative work? Is there any easy alternative to this problem

How to concatenate two Integer values into one? Given two integers n1 and n2, the task is to concatenate these two integers into one integer. Example: Input: n1 = 12, n2 = 34 Output: 1234 Input: n1 = 1, n2 = 93 Output: 193

Thanks a million!!!

Hi, I want data from the sensor once. But since the arduino is constantly powered and therefore operates, data is constantly coming from the sensor. How can I do this with an interrupt or anything? Thank you

So lets say I have arduino and whenever I write a 1 to it it sends me data over serial. If I now add an interrupt for a separate sensor(say a flow meter)...will this effect my attempts to get data from arduino when I write to it to get data?

great...Thanks for charing...subt

I can not understand

how to provide priority to the interrupt

I am working on a FASTLED project in which i so many modes. I am controlling the modes of the leds with IR Remote. My problem is when the arduino executing a function is doesn't receive the value from my remote. So can i use Ir remote and receiver led as intrrupt. So that when i pressed a button from my remote the arduino receive the value and after executing the funtion the mode will change. If it is possible then tell me how can i do this. I tried so many programs and i searched it on google too, but i didn't find it anywhere. Thanks in advance.

do I change the pin (2) to buttonpin if I want to press the select button to roll the dice, heres the code include LiquidCrystal lcd(8, 9, 4, 5, 6, 7); void setup() { lcd.begin(16, 2); lcd.setCursor (5, 0); lcd.println ("catan" ); attachInterrupt(digitalPinToInterrupt(2), btnselect_button, CHANGE); } void loop() { randNumber = random(1, 7); Serial.println(randNumber); randNumber = random(1, 7); Serial.println(randNumber); if(digitalRead(buttonPin) == 0 && lastButtonState == 1) //if button is pressed and was released last change else if(digitalRead(buttonPin) == 1 && lastButtonState == 0) //if button is not pressed, and was pressed last change { lastButtonState = 1; //record the lastButtonState } }

Did he say chicken or check in?

reference height arduino I want to know my room floor level how much height from other room in which video solution

integers as booleans *hurt*

why audio is to far?

I am still a noob but subscribed anyway :))

10 minutes well spent understanding interrupts than reading all the crappy documentation which doesn't give a clear picture.

O.o

Your example is not clear

It says ISR_button not declared. I dont think you know what youre doing
