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.

Step 1: Circuit Diagram

Lets do it!

Step 2: Arduino Serial Communication Sketch Code
