Hello. I'm a video game developer that has started to experiment with Arduino. I have an idea and I'm wondering if it's feasible.
Basically, I want to have a PC video game or digital interface send output signals to an Arduino to control something. For example, you hit a block in Mario and it sends a signal to turn a light on in a physical room. I know there's a lot about making Arduino controllers, but those are input devices.
I know you can draw graphics with a .ino program, but making a video game that way might be too difficult. I'm most familiar with C#/XNA.
Any ideas on how this might be possible? Or another way to accomplish it?
