Writing serial data on a pin on Arduino I want to write some data (GPS) to a digital port on Arduino.  As far as I understand sending data via a pin as if it were USB is possible. But I don't know what function to use. digital.Write doesn't expect any data or strings. How do I write serial data on to a digital pin
Using the arduino library "software Serial" (https://www.arduino.cc/en/Reference/SoftwareSerial) you can use any pin to write/read serial data.
