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!

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

[davidgorman]

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.

[jiveian]

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

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.

Too late video. your videos are good for students

"Thank you for your effort! Sir! I've sent you an email about mt project and I'm eagerly awaiting your response. ✨
