What is a Serial Port?

The serial port uses a nine-pin (DE-9) connector or a 25-pin (DB-25) connector. Originally, the standard used 25 pins. Because many of the pins were unused and were quite bulky, the smaller DE-9 connector became popular. Higher speed communication was needed for serial communication, such as external data storage units. In 1998, the Universal ...

Serial.print()

Prints data to the serial port as human-readable ASCII text. This command can take many forms. Numbers are printed using an ASCII character for each digit. Floats are similarly printed as ASCII digits, defaulting to two decimal places. Bytes are sent as a single character. Characters and strings are sent as is.
