Verbindung Arduino / Unity - Research Diary
Work in Process - I am nut sure how this works myself jet, but I am documenting the process.
I am working with ARDUINO UNO and UNITY 2018.4.8f
No Assets (haven't got it to work yet):
 --> the setup in Arduino works perfectly fine, but I have trouble to implement the port (it's minute 10:06 in the tutorial). I could not implement the name space SerialPort, because I can't find the "resolve" option if I right click. So I can't assign it to the new library.
- Unity versions differ to much 2012/2018)?
--> trying to find a different way to implement the SerialCommunication
Using Ardity Custom Package (free)
you can download the package on github 
Next I am going to have a look at this tutorial:
