I'm following along in Platt's Make: Electronics and I can't understand something very basic:
"The triangle inside the diode always points from positive to negative."
In the illustrated example prior to this, the resistor is attached to the black wire from the battery pack, which I thought was negative. Therefore, I thought the resistor went between the negative ground wire and the LED. Now he says it attaches to positive.
I'm very confused. Do resistors go between the LED and the ground wire or not?
Also, does it matter which direction they're facing?
