So, I raided Radio Shack's still warm body and picked up a couple Arduinos to mess around with.
I've owned them in the past and have written sketches so I'm familiar with that aspect of this.
I'm just doing the little master caution light walk through and I've got my light lighting just fine, however my button isn't changing in the game. The Serial connector is registering my presses in the window, but it doesn't have any effect in the game.
Any idea what to trouble shoot? We're definitely getting exports from the game, but not sure it's writing back to it.
