// Must call listen() on active port regularly if (!gps.isListening()) gps.listen();
The SoftwareSerial.h library is an essential tool in the Arduino ecosystem that allows developers to simulate serial communication on almost any digital pin of a microcontroller. While hardware serial is generally superior in speed and reliability, this library is a "lifesaver" for projects requiring multiple serial devices—like GPS modules, Bluetooth adapters, or MIDI controllers—on boards with limited dedicated hardware ports. softwareserial.h library
