Thanks for taking the time to present this information.

Useful. Thanks. What helps to understand classes is to treat it mentally as integrated circuits.

[larrybud]

Good basic intro to classes. Then use a real IDE and then you're really cooking!

Thanks for this excellent tutorial! Cheers from Cologne, Germany

Thanks for a clear explanation of the use of constructors and of "this". I wonder if an advantage of using "_" or "m_" before the variable name is that it makes it clear that it is a private variable that we are using, and we should not expect to be able to access it otherwise.

Excellent tutorial! Both the content and the presentation! Thank you very much!

❤Thanks a lot tutor🎉... This is exactly, what I want to learn for improvement in my carrier as Embedd Firmware developer ....! Finally, i found a treasure like channel accidentally. 😊

Your videos are super clear and awesome.

[phmiii]

I think I must enjoy your Arduino OOP class on Udemy!

[gurselturkeri]

Can you share video about Arduino and ROS2 communication?

[BearFulmer]

Im also intetested in learning about using an existing library to make functions to control things, say for instance using a fastled or neopixel library to make some of my own displays and save them, im not sure how to declare libraries inside the cpp and h files. i get multiple definitions sometimes and others its not defined.

[havehalkow]

What if I already have an object created, using an available library, but I need to make some additional methods for it? May I ask for hints on how to do that, please!

[dioutoroo]

Hi, thanks for the lesson. I tried to try it but I always get the no such file or directory error. I had put the header and the cpp files in the same folder. Could you help?

[janedoe]

Should I create class for class, and another class for class creation?

[wsmith]

Why did you not use 'this->pin' rather than just 'pin' in the 'on' and 'off' methods?

[LuckyStriker]

It's very confused.
You used 'pin' and 'pin'. Ok, you use the 'this->', but even that makes it difficult.

[oscareriksson]

Ok just have to say it. So to call 3 different functions, you wrote 2 files, both of which with more lines of code than the example. All to replace 3 lines in the example. Also there is more space allocated with the object. This is the problem with "oop" and it only becomes more difficult to follow the code and takes up more space in real programs. This is bad in embedded programming. I used to be very much into oop and all that Clean Code stuff and it can be kind of good to know it in the beginning, but understanding the hardware is better in the long run if you want to make more complex things. Knowing oop clean code principals will not help you understanding why your arduino stops working because of too many spikes in your circuit, why the timing of some thing is off etc etc..
