Can unity send an output to an external device?
Hi I wonder if it is possible to send a signal to an external device vai USB. For example if my player took damage could an output send a signal to the usb device, even say if it was a usb light that flashed evreytime a player was shot.
I really want to hook up my electric shock quazzar gun to the game so when you take damage you get a shock.
Any ideas? Thanks ..
You could try messing with the ideas outlined at the following URL:

It goes over how to interact with a USB device by treating it as a file stream and reading and writing raw data to it. It may not work, but you could give it a shot.
DISCLAI$$anonymous$$ER: I've never worked with this particular set up and it is entirely possible that you could cause damage to the device by writing incorrect data to it.
You could use the C# SerialPort class to communicate with serial devices, like a FTDI USB module or an Arduino board. A simple and useful FTDI module is the DLP-IOR4: it connects to USB but appears to the system as a serial port; this module has four relays that can be controlled by sending single characters to the serial port:
Another alternative is the DLP-IO8-G module: 8 channels that can be individually used as digital outputs, analog or digital inputs.
Anyway, you would have to use the SerialPort class; take a look at this answer, where Unity communicates with an Arduino board (microcontrolled USB board) - once the COM port is open, sending single character commands is an easy task.

That should be totally possible.
You can basically do anything that .Net allows you to do, so google away and enjoy!
Here's what I get by googling c# usb communication:
