Or use your parallel port. Oh, wait, it's 2011 now. Never mind :( USB is not the easiest beast to tame the way you are hoping to. The 5v line is typically always on, though additional power can be requested by the device. An Arduino is a good idea if you don't mind learning to write code. There is also the k8055 board which can connect to your computer via USB and has a number of inputs and outputs that you can use without much risk of frying your laptop's USB controller: http://www.maplin.co.uk/usb-experiment-interface-board-42857 Here is one of the first things I did with mine: http://matthewstechnologyblog.blogspot.com/2008/06/im-barking.html Regards, Matthew -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.ubuntu.com/UKTeam/
