This is a piece of gold!!
Very thoroughly explanation of Interrupts. Probably the best video on this topic on TH-cam yet! Thank you.
Sir content is outstanding and not lesser than a professional 👍👍👍👍I liked the idea 👍🖐️👍
Thank you very much!
Hello, sir I wanted to thank you, I got placed into my core job at MaxLinear Technologies, your project and informational videos were helpful for me in the interview and also the smartwatch project which I made was lucky part to get me the job.
One of the best pin change videos, excellent video clear and concise, AND IN FOCUS - what a bonus
9:49 Found an error!
It was confusing me for quite a while why you had set "D4_state" variable to LOW at first and then to HIGH in the very next line.
It's actually "D5_state" in line 11.
Best arduino lesson I ve ever seen!
This series of videos of Arduino 101 are great! Keep them coming please!!! Best regards from Argentina
These are really great videos, finnaly something that isn't just the basic c coding things 😅
Learned something today :)
So nicely presented. More videos like this please! Arduino 101 all the way!!! Thanks for your efforts!
One of the best Tutorials i have ever seen. Thanks brother
At last i able to understand what Interrupt is. Thanx. It will help in troubleshooting mt existing project.. thanx again❤️
Best description... thanks for all your videos....
loving these more advanced arduino videos! thanks!
Very good and deep explanation 👍 Thank you ❤
Great graphics and explanation, thanks for your time making this
We (I) would love to see a series of tutorials on the various timer modes. Input capture, phase correct PWM, fast PWM etc. Your other tutorials have helped me immensely, so big thanks!!
absolutely excellent video instruction! now let's see if i can execute!

Another thank you for a great video. Including the cool graphics where the pin diagram floats with the chip you are holding! One thing though, in English, at least in the United States, they are called an "interrupt" or "interrupts" not "interruption" or "interruptions". I suppose you could say that an interrupt can cause an interruption to the flow of your code, but an interruption would be an action, where an interrupt describes a "thing" or noun, just like a pin or a timer. We wouldn't call a pin a "pinning". :)
Loved this playlist!!!!! 😯😯😯 🤓
Best reference video series ever
So happy you like it!
@@ELECTRONOOBS I really do. Good job!
Great Videos! Thank you for you effort
Thanks a lot you explained clearly and solved my problem
Thank you! A fantastic tutorial with excellent visual examples. I have a question - does the PCINT interruption only occurs when you are in the main void loop() function? Or can it occur in a while loop in the void setup() function too?
Nice animation , thank you guru 🙏
I'm thankful for your efforts it really helped me greatly.
Excellent video! Brilliant series! Thanks
Awesome, this will help me in my menu selection function of my reflow oven project.
Are you going to explore software interrupts like timer1?
I want to update the temperature on my display graph every 2-seconds, no matter what function it is performing. I think using millis to trigger the interrupt is the best approach.
Expecting video on how to make an smps🤗
Thank you for this amazing series of videos. Maybe they dont have a lot of views but it is highly appreciated. I hope you continue publishing this type of videos and in the end make a stream or a long video where you make a full project using interrupts, timers , registers...
Thank you. That's the idea.
Hello, loved the video, but I wanted to ask , is their any way through which I can use interrupts with analog input sensor which is giving me voltages as input and my loop function directly depends on it?
A legendary video , thanks !
Awesome tutorial 🔥💥💥
Great tutorial, thanks for sharing your work
Extremely valuable information
Thank you so much ⚘😊
Thanks 👍👍
We need teachers like you in university
Well, that was extremely good. Thank you!
Great lesson, amazing content thank u well done man.
Thank you sir, very interesting and valuable information.
As usual amazing 😍. However,
I couldn't find anything regarding how to do Arduino bootload Atmega 32A anywhere. You are my last hope. It's very important for me! Would you please make a video regarding how to do Arduino bootload Atmega 32A?
Thanks in advance!
Very good ! But all variables should be declared with “volatile” that are changed in an ISR. For example (at 9:47 ) code: volatile bool D4_state = LOW
These are the great stuff ❤️
Excellent explanation!
hi thank you for your video. Can I ask you the name of software that you used for making the edit of the video. Thank you .
Great tutorial! Thank you. Is it really bad idea to make some processing in the ISR? Many times you'd like to ignore other interrupts before current interrupt is processed.
Great video as usual 👍👍
Thx for excellent tuts.
If wanting to return the clock cykle value instead of the micros() for better accuracy. Say one want to use the PCI for triggering two mics to get the angle of arrival, whats the maximum resoultion on an UNO? Lots of my students namely want to do "robots" that can get the angle of arrival of sound to stear them... :) im stuck there..
Excellent video. I liked it
Nice explanation 👍🏻
Thanks for helping out!
Whoa I think you have complete knowledge about Arduino programming.... Thanks for such wonderful contents.
Sir there are many other development boards like pyboard, teensy, stm32 etc are available, please make s video on them....
Thank you. I'm preparing some videos foe STM32 to start. Then we can see other boards...
Please make a video about analog port manipulation. Thanks!
very very very gooooood, just I"ll want to need, good explanation,from Brazil
learnt a lot thanxx...
Really useful😍please do a video on timer interrupt.
Nice explanation
It's a very good lesson. I wondered what program did you create this video with? The animations and movements are very nice.
perfect !!!
I love your videos. Also, I understand debounce conceptually, but can you provide an example of button debouncing
Sometime?
Excellent
Hello boss, I have some problem. I am using two pin for button, both are at same PCINT0. I am using input_pullup for button press.. pls let me know how to do both ISR. I have checked ur tutorial in ur blog, but could not figureed out. pls let me know here
My thanks. waiting for stm32f4 video tutorials
Hi brother which SW are you using for video editing... Good presentation every time...
By the way I am making DIY AND ARDUINO projects please take a look at it 😅
I use After Effects
@@ELECTRONOOBS thanks dear...
Teşekkürler...
Hi, I don't know if you reply to comments on old videos but here goes. Could you use interrupts to run both InfraRed Transmit -> InfraRed Receiver on a single Arduino nano (IRremote.hpp)? Normally you would be stuck in IrSender until you have sent a complete code (e.g. IrSender.sendNEC(sAddress, sCommand, sRepeats);) and if you are receiving you would be stuck in IrReceiver until you receive the IR code. You couldn't transmit and receive at the same time. I was easily able to do this with two arduino's (one Tx and one Rx) but could it be done with one? So just to be clear...I'm trying to transmit an IR code and simultaneously receive the same code. Maybe what I'm asking for is true multi-tasking which much more than an ISR.
amazing! wow bro
Hi sir I have a small doubt how to denounce the interrupt please help me
what does the EIMFR and PCIFR register do
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
Great
2:34 these are not instructions but statements. A statement can result in multiple instructions in the compiled output.
I'm waiting for nixie watch part 2.
Please upload the video soon..
Normally interrupts have priority levels and lower priority interrupts are left pending until the higher priority interrupts are completed.
Also higher priority interrupts can interrupt lower priority interrupts.
Is this also true on the Atmega or are all other interrupts really blocked when an interrupt is called?
With PCINT on the ARduino UNO only has one level of interrupt. Also, as I say in the video, interrupts are turned off during an ISR. If the ISR for interrupt 0 is executing and interrupt 1 occurs, it will be held until interrupts are turned on again after I0 has finished.
Ta bien 👍
cool tutorials,ive been trying to make demonstration videos with animations like this can you please can you please give me a guide of software's i should buy
Can i use PCINT with SoftwareSerial?
Actually i have a question if 2 pins of port d are used for pcint then is we can use other pins of port d as output pins?
Yes you can. You can define PCINT for some pins and use the rest of the port as OUTPUT and set them LOW/HIGH.
Programming interrupts was my daily bread.
good video!
Thank you!
Sir. Plz do a video on long range wired sensors and long range LED PWM control and power supply. Plz sir..
hallo ;I think the arduino UNO have Atmega328P. This uc doesn't have any PCINT. arduino NANO has 3 PCINT. thanks
very good video
Thanks!
hi sir i want your help in my project i am new to arduino and i want to control a led brightness using one pushbutton and if long press it will increase or decrease the brightness of the led can you please give me the code i searched on google and youtube but i didnt find what i needed pls can you give the code for it
Where does he get the papers
need more on AVR C and at328 advanced functionality
Will You move to AVR studio? I think that ones a pretty good IDE as well. I would love to see You teach us coding with AVR studio.
maybe in the future... never used that yet....
@HalfSpeedMastering man, u know alot man. Maybe u can teach some trade of ur resources? I'd love to continue tinkering with AVRs but got stuck with ADC - its so complicated:
tienes el mismo video en castellano?
continue making Arduino 101 Tutorial
Can you please make a walkie-talkie
With nrf24L01 transceiver and with Arduino 👍🏻👍🏻👍🏻
Amazing video Sir .Please dont move the text in the video it makes it a little hard to read.
You said that PCINT works not only for RISING OR FALLING but also for LOW or HIGH. I was looking for such case with LOW or HIGH, but I did not found. Are you sure you are correct?
Hi. No, what I've said is that PCINT only works with low or high. It could not detect edges. So you have to detect the edges by storing the previous state and compare with the new stare and by that you know if it went from low to high or from high to low.
Please make a video on arduino bit banging ...
Buna electronoobs ai putea sa imi răspunzi si mie la o intrebare legata de arduino
good
These is code error in ur site. See step 6 in pin vhange interrupt
Bro I had a question about your personal life.....I know that youtube is your full time career and you have done engineering.....so what is you detailed educational qualification???
I'm an electronic engineer.
@@ELECTRONOOBS ohh ok so you learnt coding in your regular education or you took some extra coaching??
In English technical jargon the word "Interrupts" is proper ...and "Interruptions" - is not.
This is more like Arduino 301; 101 is usually a beginners course.
Please make an arduino key logger please Love from India
👌
