I'm just picking up Godot, and was wondering if I can connect to and receive data from a serial port?

Desktop and Android, both would be great. But desktop is the most important.

Thanks!

This Youtube video shows it's possible to connect to an Arduino. I'm not sure on reading/writing to and from an Arduino, but there is some code in the comments and it looks like you can at least write to an Arduino.

Hello.. what was the solution for this problem? I am facing the same issue.When I open serial monitor in arduino IDE then only arduino code works. Otherwise I receive the same messages back to RPi. How to make sure code works without opening serial monitor?
