UE4Duino

Unreal Engine 4 plugin for Arduino (COM port) communication on Windows

How to use

Create a Plugins folder in your project directory. Place the folder UE4Duino (the one that contains Source, Resources etc) in the Plugins folder.

You can use the Open Serial Port function and store the result in a variable Example 1

Or create the Serial object yourself and open the port afterwards Example 2 Either way, never forget to call ClosePort on the Serial instance before quitting the game. EndPlayEvent is a good place for that. If you forget to do it, you'll have to unplug the Arduino (or other COM device) from the PC and plug it back.

You can set the type of line endings used with the WriteLine function. Example 3

There's an example Arduino script in UE4Duino/ArduinoTypesExample. It demonstrates how to send floats, ints and strings to Unreal. Example 4 Example 5
