✨⚙️ Features
- A peer-to-peer wireless communication system using Arduino Uno,
- This project demonstrates encoding text into Morse code,
- Transmitting it wirelessly, and decoding it back into human-readable form.
- NRF24L01 transceiver modules to transmit and receive Morse code messages.
- It uses 2.4GHz global open ISM band, license-free in India.
- Range upto 1500 meters in line of sight with SMA Antenna.
- Display messages on a 16×2 LCD screen
- Option to build circuit with or without I2C module
📖 Introduction
Morse code is a communication method that uses short and long signals
- Different combination and sequence of dots
·and dashes–to encode text in morse code.
(space too for switching between words.) - This project implements a wireless Morse code communication system using NRF24L01 modules for transmission and reception, and a 16×2 LCD to display messages.
