So the first test I did when I got my PICAXE chip/project board is the LED test with the LED and 330 ohm resistor on output 4. I just wanted to know exactly why you connect the LED between the V+ and output pin? Just trying to figure this out so I understand it for hooking up 4 LEDs in parallel to output 4. If it were a simple circuit (battery, LEDs, and resistors), the current would flow from the battery, to the resistors, through the LEDs, and then to the 0V of the battery. But it seems that with the chip in the project board, it is the oposite. So do I just attach the LEDs to the V+ and then add a resistor to each of the LEDs, and then the other end of the resistors to the output 4?
