Morse Code Decoder Using Arduino

Abstract: Morse code, a communication method based on sequences of dots and dashes, plays an important role in various communication systems, especially in emergency situations and assistive technologies. This paper presents a simple yet effective Morse code decoder system using an Arduino UNO, a 16x2 LCD with an I2C interface, and a laptop for input. The proposed system decodes Morse code signals sent from a laptop and displays the corresponding text on the LCD. The aim of this work is to develop an efficient and cost-effective solution for both communication and assistive purposes.
