How to execute code only on hardware?

This extension has a cpp file simply to avoid strobing a simulator pin
https://github.com/KitronikLtd/pxt-kitronik-Craft-and-Code/blob/master/customPinControl.cpp

I suggested using control.deviceName(). Is there a better way?

@martinwork that seems good way to me. Other hardware specific API are deviceSerialNumber, hardwareVersion etc. But harder to parse on what is for hardware and what is not.
