Using Visual Studio (C++)

Using Arduino Interfacing w/ Software on the Computer
1

I'm looking for a way to send software values to the Arduino.

I have an interface app written in C++ that extracts flight data from Microsoft's Flight Simulator. (Think Engine RPM in this case)

Much like a Tach, I want to send the RPM (0-2800) value via a C++ app (Or C#) to the Arduino, which will increase/decrease the on/off freq on a digital output.

Has this been done in other arenas?

Not sure what you mean by "in other arenas", but, yes, plenty of people have written C# applications to talk to the Arduino.
