Waits for the transmission of outgoing serial data to complete. (Prior to Arduino 1.0, this instead removed any buffered incoming serial data.)
flush() inherits from the Stream utility class.
- Serial: serial port object. See the list of available serial ports for each board on the Serial main page.
※ NOTES AND WARNINGS:
Serial functions are not only used for the communication between an Arduino board and Serial Monitor of Arduino IDE but also used for the communication between:
- An Arduino board and other Arduino board
- An Arduino board and other sensors/devices
- An Arduino board and computer (any Serial software on computer)
