OK, I've now solved this issue, what I now want to do is send a pulse
over the port.
I assume that I need to use a timer to do this, but I'm not sure how to
go about it.
I want it to do the following:
turn the light on for a specified period, turn it off for a specified

so for example the light would do the following:
0 1 0 1 0 1 0 1 ...
Thanks in advance,
