EMBEDDED PROJECT 2 - PC COMMAND LED AND ALARM SYSTEM USING STM32.

# STM32 PC Command Controlled LED & Alarm System | UART Serial Communication Project This project demonstrates a real-time embedded system developed using an STM32 Nucleo board and PlatformIO. The system allows users to control an LED and buzzer directly from a PC through UART serial communication using simple keyboard commands. The project was designed to demonstrate embedded C programming, GPIO interfacing, UART communication, and real-time hardware control using STM32 microcontrollers. ## Features ✅ LED ON/OFF Control ✅ Normal Blink Mode ✅ Fast Blink Mode ✅ Slow Blink Mode ✅ SOS Emergency Pattern ✅ Alarm Mode with Buzzer ✅ Real-Time UART Serial Commands ✅ No Board Reset Required ✅ STM32 + PlatformIO Development ## Commands Used 1 → LED ON 2 → LED OFF 3 → Blink Mode 4 → Fast Blink 5 → Slow Blink 6 → SOS Pattern 7 → Alarm Mode ## Hardware Components * STM32 Nucleo Board * LED * Active Buzzer * Resistor * Breadboard * Jumper Wires * USB Cable ## Software Used * Visual Studio Code * PlatformIO * Embedded C * GitHub ## Concepts Covered * Embedded Systems * UART Serial Communication * GPIO Control * Real-Time Embedded Programming * STM32 Programming * Microcontroller Projects ## GitHub Repository Add your GitHub repository link here. ## Author Veeramanikanta Sai Kaja Technological University Dublin Student ID: A00046919 #STM32 #EmbeddedSystems #PlatformIO #UART #Microcontroller #EmbeddedC #IoT #ElectronicsProject #STM32Nucleo #EngineeringProject
