Just wanted to say a quick apology for the delay in getting Lesson 13 out! It's been almost 2 months since Lesson 12, and I know many of you were eagerly waiting. Some important works pushed things back a bit. The good news is Lesson 13 is finally here, and we're diving into the exciting world of hardware interrupts! I hope you find it informative and helpful. As always, feel free to leave any questions or comments below. Thank you!

Is there a chance for a video about software interrupts on Uno r4? So far there is nothing in this matter anywhere 😢

I've been binging your videos. They are really nice and informative. May we also have a tutorial about RTOS? Along with interrupts, I think this is also a very good and must see for beginners like us since we are stuck in a somewhat "linear" flow of our programs for our projects. I'm subscribing, hoping to see more content from you especially other micro controllers like STM32 and ESP32 even tackle other peripherals/lines like CAN and DMA. Thanks for the video!

wow this very clear explanation , thanks a lot

Thanks for the video. Note that I think you should have made it clearer that the 'LOW' mode of invoking the ISR blocks completely all the rest of the loop() code during the complete time the button is pressed, which makes it almost useless in real life. Instead of making long example where you merely illustrate by example how the library method works, I think it would be more helpfull, especially to beginner coders out there, if you explained how we should use the ISR in a real-life situation. In other words, we want to learn from your experience more that just what are the library options.

I'm using atmega and stepper driver for nema42. The problème I'm facing is big interférences wich disturbs arduino. Inputs become random even i use an external pullup resistor of 10k. The project works perfectly when the motor is off. How to fix EMI in this case. Note that in my project, i'm using two motors, a stepper nema42 and a 0.5kw 3 phase motor.

I love the video. It works great as long as i don't hold the button down for a bit. If I do, it interrupts when I finally release the button. Trying to find a way to prevent that.

Thanks! Try experimenting with different interrupt modes 😊

@@joedgoh I have tried them all. I’m using a nano, maybe that is the issue. I’ll keep working on it.

nice video sir. Do you also have a hardware and database interaction crash course?

@joedgoh 7 ай бұрын

As of now, this is the only playlist with database interaction. Internet of Things: kzbin.info/aero/PLVTsfY7Kr9qjVkq8aJmTXbiiy5h41ayRL In the future lessons, I will connect this Arduino to a database.
