Hello, I know this is a somewhat subjective question but I am looking for the best all around tutorial series on arduino. Ideally this would cover basic electronics (what is ground, what is a circuit etc.) and also explain things like i2c, (which I still don't understand), clock rate, baud rate etc.
I know adafruit's are good, but it doesn't seem to be as much of a full course as I hoped. I just came across tronixstuff's http://tronixstuff.com/tutorials/ and they seem pretty good. I just want to know because I am going to buy all the accompanying sensors and I want to be sure I head down the right path.
Does anybody have experience with tronixstuff or any other great "class-styled' tutorials? I am looking to avoid a book as I like pictures and having it be online.
