Yep, he doesn't seem to have any idea of how a breadboard works. In fact, he's got it completely backwards (LEDs on the power rails and power rails in the component rows). It probably won't blow the ports with the resistors there, but it definitely won't work the way he says it does. Also, the Arduino IDE already has a serial terminal built in, so all of the Processing terminal handling stuff is moot. Final point is that running motors from the same supply as the Arduino tends to break down if you put a decent load on them - you'll get brown outs and weird resets. On the plus side, he does include his bibliography on the last page, so you can check out the original tutorials. That's a pretty decent set of links and books.
