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