In the section titled "Scheming schematic" it explains that the LED 's positive pin is connected to the 5V and the negative pin connected to the resistor. In the schematic and the picture the resistor is connected to the positive pin. I know it does not matter since it works both ways, but it may confuse people.

confused about resistors
so, yeah... this did confuse me a bit. my understanding is that the resistor needs to be between the LED and power - is that correct? or does it just need to be in series somewhere?

Re: Tiny insignificant error in Tutrial 3
I think the water analogy works regardless of where the resistor is too...
If you've got a sewer pipe (wire) that shrinks down to a garden hose (resistor), then opens back up to a sewer pipe on the other side (wire)... The current is going to be the same everywhere.
The water pressure (voltage) will change from one side to the other but the current would be identical.
