@feitingschatten1 3 жыл бұрын

I've been programming for 25 years. I still get scared when things work perfectly the first time. Side note: Defensive programming is great but you gotta be experienced to gain an intuition, along with knowing if you should put the defensive code at the top (where the input happens) or bottom (where processing happens). There's no right answer, it depends on how you choose to architect it. But some things, like displaying an LED on a board that only take Int values, with defined maximums and minimums... don't really need a defense against too big/wrong type. However, when user input is free, or other things can happen, definitely write defensively.

Today's comment Paul . I just realized how much difference there is in your videos when compared to the ones I used to watch. Other video presenters are either a: proving how much they know by zipping through each item thinking that speech speed indicates a vast subject knowledge or b: they expect the average newbie to remember everything that has been on screen minutes before. Both useless to me as I have a condition which affects short term memory. The fact that all info is on screen at the same time helps me an awful lot. I simply have to rewatch 2 -3 times before the subject matter sinks in. Thank you Paul for your efforts. They are very much appreciated.

Since it is almost 1/4 of this course playlist I would like to share my results! I did these 15 videos in 2 days because the explanation and the video format are just on another level therefore it was very easy to learn. I really enjoyed every second of this course. In fact, I tried Arduino courses before but they were not as great as this course is. I treated Arduino as just a piece of hardware but I never understood the depth of its work. I never thought deeply about physics behind this. Maybe that is why I never felt confident in my Arduino skills. Now I feel much more confident and I have so much motivation! Thank you, Mr Paul McWhorter! Much love from Kazakhstan

Thank you for today's lesson. I really liked how you put the curly clause symbols first, then you put the for with the two parenthesis, and then you declared the variable j, and then you populated the parenthesis's to tell it how to act by putting the declared value of j in the parenthesis, and the you put the condition, and then you incremented j by 1. By doing that you for the first time allowed me to understand the syntax of a for loop! Thank you!

My goal is to try to get grips with modern electronics and get back to a design technician role which is probably very difficult at the current economic situation, but I do like a good challenge. Furthermore, I would like to assure you that you ARE doing a great job with your teaching method. I also find myself doing the assignments that you set at the end of some tutorials (and experiment with some tweaking of the code ... and like you I get immense pleasure when I see my attempt successful. I bought my kit some years back and went on a very thorough and complete course for Arduino (no names mentioned!) but lost interest some time down the road. I thank you from the bottom of my heart for rekindling my passion for modern electronics and programming combination. Please continue the great work. 5/5 *
