It's Sunday night here, and I am lying watch Expendables 2 with the boy, kind of half-thinking about work tomorrow.l, and something has just struck me...
There has been a spate of office moves and relocations at work, and a few weeks ago one of my colleagues left an archane VGA splitter box on my desk.
It is one in, two out, but... what if I was to remove one of the outputs and wire it as an additional input and use the master Arduino to switch which port the splitter receives data from???
Answers on a postcard please :)
