This is my first post. The context of the problem I am facing is that I am an experimental psychologist and I am attempting to learn Unreal so I can develop immersive environments so I can run psychological experiments in them. The issue I am currently facing is that I want to pair an Arduino board that controls voltage output to a thermal pain stimulator. The stimulator will also have an input back to the board that reads its surface temperature. The issue I am faced with is how to control the input and read the output of the Arduino so that I can control the stimulator. The idea is that events in the game will trigger the thermal pain stimulator. I have done some looking online and in this forum and it definitely seems possible (perhaps through a windows thread) through the serial port. Does anyone have any input on how to get this project working or specific resources that I can check out? I have some moderate programming skills, unfortunately not in C or C++. So imagine there is going to be a learning curve here but I am cool with that. I just need to figure out where to start.
