I will use an Adruino in my livingroom. To connect with my computer (Apple) I found Eventghost. But that don't work on a Macosx without Windows on bootcamp. Is there a similar program like Eventghost that will run on Macosx?
While parts of the core of EG are generic, quite a bit of the messaging infrastructure is Windows specific. There is also all of the Sound/Monitor/Registry stuff that is Windows specific. So EG will not work on Mac/Linux. I've never looked for a Mac comparable product.
Eventghost is built to directly interface with the underlying system infrastucture in windows, thus it will not work in any other OS despite the fact that its in python (which does work on all OS's). Never tried it in wine though... could be interesting to see what does work.
