Hi there;

I'm working on a project that requires 3 to 5 volts of voltage to be sent to one of the GPIO pins when sound is heard on a virtual sound card when sound is heard on that virtual device (as sound is not always present).

All tutorials I've researched demonstrate how to do this using a sound sensor module but not a virtual sound card.

I need something that detects sound on that virtual card/device in Windows, and then activates 3-5 volts to a GPIO pin (using Latte Panda which has Windows with integrated Arduino).

Any assistance or guidance would be much appreciated

Thanks in advanced.
