Morse Code Beeper

Wireless communication system using Arduino microcontrollers with SPI-based transceiver modules for peer-to-peer messaging.

ArduinoC++SPI ProtocolRF Transceivers

Overview

A complete embedded systems project enabling wireless peer-to-peer communication between multiple Arduino microcontrollers using Morse code as the communication medium.

Key Features

  • Wireless SPI Communication: Robust wireless communication using SPI protocol with RF transceiver modules.

  • Multi-Device Network: Support for multiple Arduino devices communicating within the same network, each with unique identifiers.

  • UID-Based Addressing: Phone number-like addressing system where each Arduino has a unique identifier (UID), allowing targeted message delivery to specific devices.

  • Morse Code Interface: Intuitive input/output using Morse code patterns, bridging classic communication methods with modern embedded systems.

Technical Implementation

The system architecture includes:

  • Hardware: Arduino microcontrollers paired with nRF24L01 transceiver modules
  • Protocol: Custom SPI-based communication protocol for reliable data transfer
  • Addressing: Unique identifier system for device targeting similar to phone numbers
  • Software: C++ firmware with interrupt-driven I/O for responsive performance

Learning Outcomes

This project provided hands-on experience with:

  • Embedded systems programming in C++
  • Wireless communication protocols
  • SPI interface implementation
  • Multi-device network architecture
  • Real-time signal processing
