Strings are also useful for storing the user input. For example, the characters that a user types on a keypad connected to the Arduino. There are two types of strings in Arduino programming − Arrays of characters, which are the same as the strings used in C programming. The Arduino String, which lets us use a string object in a sketch.

Arduino and Visual Basic Part 1: Receiving Data From the Arduino. The Arduino Sketch sends the string “1234” over the serial connection once every second. At the same time it blinks the built in LED on pin 13. Since the program uses basic serial communication it should work with all versions of the Arduino and other microprocessors.

String Addition Operator. You can add Strings together in a variety of ways. This is called concatenation and it results in the original String being longer by the length of the String or character array with which you concatenate it. The + operator allows you to combine a String with another String, with a constant character array, an ASCII representation of a constant or variable number, or
