StreamString stream; stream.print("Hello, "); stream.println("world!"); Serial.print(stream);
StreamString stream(Serial); while (stream.available() > 0) { char c = stream.read(); Serial.print(c); }Here, we create a StreamString object using the Serial stream as input, then use the available() and read() methods to read data from the stream and print it to the Serial monitor. Overall, StreamString is a library in the Arduino package that can be used to create and manipulate strings with various input and output streams.
