Communicating data is important - your Arduino might be used as a sensor, or to control some hardware, and therefore needs to either send data to another computer, or to receive commands from another computer. The core necessity is sending and receiving data. This video is an in-depth look at how to implement NRZ (Non-Return-To-Zero) data communications using a single pin on the Arduino. Also in the video is a look at connecting a certain LCD panel to an Arduino.
