Hello! I would like to share with you my custom build DIY Train Sim World 2 Controller. It is based on Arduino and works to a computer as standard keyboard. Throttle and brake leavers do use potenciometers and some clever mathematical algoritems to translate the changes to button presses on the keyboard so that the game can accemt the inputs. As External Controller Suport is on the Road Map, I am prepearing a software update, so that throtlle and brakes will works as yosticks (on condition that the game will suport that after added suport for External Controllers). Right now there is some small delay if you change the leaver too fast, but that should be fixed with External Controller support. If you have any guestions regarding the controller feel fre to ask! You can see short video of it working here: FAQ: 1 Is it for sale? Sorry, it is not. 2 Can I get your Arduino code? Sorry, no.
