How to implement arduino serial communication with ue5

Arduino is a popular open source hardware platform developed by a team in Italy to provide makers, artists, hobbyists, and makers with easy-to-use IoT development solutions. UE5 (Unreal Engine 5) is a leading game engine mainly used for making video games and virtual reality applications. In this article, we will explore how to use Arduino to communicate with UE5 in order to interact the Arduino's input and output with a virtual reality environment.

First, we need to clarify some basic concepts. Arduino's input and output are usually performed through the serial port, while UE5 usually uses C++ to write game logic and interaction code. Therefore, we need to understand how to set up serial communication on Arduino and how to write C++ code in UE5 to read serial port data.

On Arduino, we can use the Serial library to configure and manage serial communication. The Serial library contains some simple and easy-to-use functions that can help us easily set the parameters of the serial port, such as baud rate, data bits, parity bits, etc. Here is a simple example code that demonstrates how to configure and open a serial port on an Arduino:

void setup() {
  // 初始化串口通信
  Serial.begin(9600);
}

void loop() {
  // 向串口发送数据
  Serial.println("Hello, UE5!");

  // 从串口接收数据
  if (Serial.available()) {
    char c = Serial.read();
    Serial.print("Received data: ");
    Serial.println(c);
  }
}

In UE5, we can use the UE4Duino plug-in to implement serial communication. This plug-in provides a set of simple and easy-to-use functions that can help us open, read and write serial port data. Here is a simple example code that demonstrates how to read data sent by Arduino in UE5:

#include "UE4Duino.h"

void ReadSerialData() {
  TSharedPtr<FSerialPort> Port = FSerialPort::Create(TEXT("COM3"), 9600, 8, EBaudRate::BR_9600, EParity::None, EStopBits::One);
  FString Data;
  
  if (Port.IsValid()) {
    Port->Open();
    
    if (Port->IsOpened()) {
      Port->Read(Data);
      UE_LOG(LogTemp, Warning, TEXT("Received data: %s"), *Data);
    }
    
    Port->Close();
  }
}

It should be noted that when using the UE4Duino plug-in, we need to import the plug-in into the UE5 project and enable the plug-in in the project settings. In addition, we also need to include the header file of the plug-in in the project code and call related functions where serial communication is needed.

Finally, it is worth mentioning that when conducting serial communication between Arduino and UE5, we need to ensure that the communication protocol between the two is consistent. For example, when sending data, we need to agree on which encoding method and data format to use so that the data can be correctly parsed and processed at the receiving end. Therefore, it is recommended to carry out necessary protocol design and testing before implementing serial port communication to ensure the stability and reliability of communication.

In short, through the above steps, we can achieve serial communication between Arduino and UE5 relatively simply. This provides the possibility for us to control physical devices in a virtual reality environment or transfer physical environment data to virtual reality applications.
