Two serial port communications?

Projects General Guidance
1

Hi all,

I am planning on a project that involves the Unity3D game engine (which runs on PC) and Arduino. What I am envisioning it to work is that I will have 6 IR sensors connected to an Arduino board which would send the sensor values to Unity3D via serial port communication. I am pretty certain that it will work because I've found some useful information on how to do that. What I would like to know is whether it's possible to connect a second Arduino board to the PC, and have two serial port communications going simultaneously between Unity3D and the two Arduino boards? Essentially what I want to achieve is to control the two Arduino boards at the same time by establishing two serial port communications. Would that be possible to do?

Thanks.

The two arduino boards will show up as two different ports.

So if Unity supports reading / writing from/to two ports you should be ok.

Except possibly for the "at the same time" requirement. Nothing happens simultaneously.

What is the second Arduino going to be doing?

Regarding the IR sensors you are reading, what are they sensing? How do you keep them separate?

Are you able to reliably read all 6 and send data the Serial Monitor?
