SerialEvent

This example demonstrates use of the serialEvent() function. This function is automatically called at the end of loop() when there is serial data available in the buffer. In this case, each character found is added to a string until a newline is found. Then the string is printed and set back to null.

Hardware Required

• Arduino Board

Circuit

None, but the board has to be connected to the computer; the Arduino Software (IDE) serial monitor may be used to communicate the single or multiple characters and receive the string back.
