    I'm completely new to hardware in general. I just got a raspberry pi and was messing around trying to get an LED to light up.

    I have everything wired like the picture below. I am using a 330ohm resister, which I believe is bigger therefore ok then what is required.
    also (sorry this is my first time using any program to draw a circuit)
    The program runs successfully, but no light comes on. I know the LED is good as I've tested it on the arduino. Anybody care to explain my wiring fault?

    import RPi.GPIO as GPIO
    GPIO.setup(11, GPIO.OUT)
    GPIO.output(11, True)
    Changing to GPIO pin 0 results
    Traceback (most recent call last):
      File "", line 5, in <module>
        GPIO.setup(0, GPIO.OUT)
    RPi.GPIO.InvalidChannelException: The channel sent is invalid on a Raspberry Pi

    Are you sure the led is connected the right way?

    Check if the two pins you connect actually gives a voltage output on your voltmeter when you run your program.

    Try 'GPIO.setmode(GPIO.BCM)' or when using GPIO.BOARD use pin #23.
