Arduino for beginners

This was a big experiment to introduce people to Arduino and the capabilities.
It was a gigantic failure. I am lucky that I don't have a dozen people saying I spent $3 and you owe me to get this to work.

I can see how you might see it that way but the view from the other side is different.
I appreciate what you have done even if it was over my head. One day I hope to get to where I can understand enough to make several of the things you have posted and I'm sure the people that are already above moron level are more appreciative still.
It is a fine line and sometimes intentions and comments are misconstrued. You don't owe anything to anyone so everything you do is 100% x 10 to your credit and good will. I have tried to teach different people different things and felt the same but even if it has taken years later, I have then bumped into people who have said I learned this from you or you were the one that motivated me. The good Karma may not be apparent for some time or at all but not to say it is not there and your efforts are not appreciated even if it does not sound like it.

George,
Maybe the rest of us were just lucky enough to be introduced to electronics at an impressionable age, or spared the shock and awe somehow.
I do appreciate your humility on the matter, so if you're determined to learn, then this is it:

It was one of the most important books I ever read. I still have my copy, though now I only look at it to enjoy the illustrations of course!
The link above is the revised edition. I think my copy is from 1985 or so. The new edition is still in print.
Just consider how much electronics have changed in 30 years, so any electronics book still in print this long must be good!

The Forest Mims books are invaluable. I still have my op amp and 555 timer cookbooks and still use circuits from them!
OperaHouse:
The ground plane is an homage to a long lost post called something like FET DESTROYER. The OP had blown way more than $100 woth of high powered FET and IGBT on a UNO windmill water heater dump. Understandably he was beginning to believe it wasn't possible to get working. Everyone had him hanging unbelievable amounts of crap on the FET for spike protection. That solution didn't make sense to me, there had to be another reason. When I finally got time I did some old fashioned circuit sleuthing. I found the problem elsewhere in the electronics. The OP then got it working. A little technical nuance stopped what was otherwise an exemplary execution of hardware and code.
Arduino may be a lot like the guy who says he hasn't liked the women he has been going out with. And you tell him he should date super models. Not necessarily bad advice.
All electronics is the assembly of basic building blocks like voltage dividers and output devices. Understanding the operation of these allows you to build anything. I understand the desire to have a turnkey laid out system. That just doesn't get you very far. Deciphering pins from code is just a matter of finding the analog read and digital write statements. That tells you the pin number. Unlike on other microprocessor chips the pins are directly labeled A1 for analog and D6 for digital. Just saying You don't understand gives me no way to answer. Asking why is this resistor here or how does the signal get out gives me something to work with. There are relatively few basic circuits which will allow you to do everything. This is the building block approach I have used. Perhaps a series of hardware posts would be helpful.
Since this is the scary month of October, it is time to post some frighting photos. I needed an 80V buck converter of just a couple amps. A block of wood, NANO and an old TV cut up. The ground planers won't sleep tonight! Just tell me you can't make something look as good as this.
DamonHD:
I have a wood 'ground plane' just like that at my feet! B^>
Just like the original breadboards, before all this fancy conductive stuff...
