Serial Communication With Arduino

Source: http://www.theorycircuit.com/serial-communication-with-arduino/

Here this project shows how to communicate with arduino serial terminal? For an application we have chosen four LEDs to indicate direction.
In a bread board four LEDs are placed in different direction and the Arduino sketch composed to control those LEDs with computer numeric key by pressing particular key we can get output.
