It disables interrupts for the entire time that a character is being sent OR received, and it cannot do both at the same time (unlike all the other serial choices). It works on any two pins, but it is very inefficient. It works on any two pins, but only at baud rates 9600, 1920. Only one instance is allowed, and it is must be used on one of the Input Capture pins (pins 8 & 9 for a Nano). The Nano only has Serial.ĪltSoftSerial, the best of the software serial libraries. On some Arduinos, there are extra HardwareSerial ports, called Serial1, Serial2, etc. Simply use the pre-defined Serial variable.
