    Lightbulb USB Powered Light Bulb

    I'm trying to power a light bulb on my fish tank so I can turn it on and off remotely.

    I believe powering the light bulb is as simple as connecting the USB's black and red cables to the matching cables on the bulb connector.

    However, how would I turn the bulb off from my computer without unplugging the USB. I think I need to use the bus but what is the missing component I need between the computer and bulb? Or is it as simple as umount?

    I think if it's unmounted, it's still getting power, otherwise unmounted devices would not be detected.

    I can't solve the problem, but I can assure you this
    When I find myself burried in errors, Windows Help appears to me; speaking words of wisdom, Reboot!
