// converting a constant string into a String object:

// using an int and a base:
stringOne = String(analogRead(A0), DEC);
// prints "453" or whatever the value of analogRead(A0) is
Serial.println(stringOne);
// using an int and a base (hexadecimal):
stringOne = String(45, HEX);
// prints "2d", which is the hexadecimal version of decimal 45:
Serial.println(stringOne);
// using an int and a base (binary)
stringOne = String(255, BIN);
// prints "11111111" which is the binary value of 255

// using a long and a base:
stringOne = String(millis(), DEC);
// prints "123456" or whatever the value of millis() is:
Serial.println(stringOne);
// do nothing while true:
