This project echoes back any text sent to the Arduino board through serial communication.
The device listens for incoming data on the serial port. When it receives a character, it immediately sends that same character back to the sender. This creates a mirror effect where anything typed into the serial monitor appears again as if the Arduino is repeating it back.
