Arduino Workshop - Chapter 5 - Interrupts

In this section, we'll look at how to use interrupts. You may have heard of them before, and they're a great way to increase your program's efficiency when dealing with hardware inputs.

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

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

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

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

Great video.. best on using interrupts

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

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

[chuckthebull]

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.

thanks for your quality video. keep up the work

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

[hubercats]

Very helpful video. Thanks for sharing.

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

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

[cosimoferreri]

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

Great teacher you are :) insta sub, thank you
