This project is a Raspberry Pi-based burglar alarm system developed in C++ that integrates motion detection, temperature-change monitoring, keypad control, LCD status display, and independent alarm outputs.
The system uses a PIR motion sensor to detect movement and a thermistor connected through an ADS7830 IยฒC analog-to-digital converter to monitor environmental temperature changes. A 4x4 keypad allows the user to arm and disarm the system, while a 16x2 IยฒC LCD provides real-time system status feedback.
## Features
* Keypad-controlled arm/disarm operation * PIR motion sensor monitoring * Thermistor-based temperature-change detection * ADS7830 IยฒC ADC integration * 16x2 IยฒC LCD user interface * Independent motion and temperature alarms * Startup reliability improvements for LCD initialization * Makefile-based build system
## Hardware
* Raspberry Pi 4 Model B * PIR Motion Sensor * ADS7830 IยฒC ADC * Thermistor Voltage Divider * 16x2 IยฒC LCD with PCF8574 Backpack * 4x4 Matrix Keypad * Active Buzzer * LED
## Embedded Concepts Demonstrated
* Embedded Linux Development * C++ Programming * GPIO Interfacing * IยฒC Communication * ADC-Based Sensor Monitoring * Hardware/Software Integration * Embedded Debugging and Troubleshooting * Build Automation with Makefiles

Did you know ESP32 already has a built-in temperature sensor? ๐ณ In this video, I showed how to read the internal temperature sensor of ESP32 and monitor the chip temperature in real time. This sensor is mainly used for: Thermal monitoring Overheating detection Power optimization Internal chip temperature analysis I also explained why the readings change when CPU load or WiFi usage increases ๐ฅ Next video โ OLED / IoT dashboard integration ๐
Are you about to shelve your project because your microcontroller ran out of pins? Stop right there! Discover how a simple port expander IC can save your circuit and give you massive I/O capacity in seconds. ๐
In this tech fundamental tutorial, we explore the power of port expanders. Learn how to gain 16 programmable input and output pins using just a serial communication protocol. We cover the straightforward setup: supplying power, connecting data and clock lines, and configuring reset and address pins. For those who want to push the boundaries, we even explain how to connect 8 ICs in parallel for a massive 128-pin setup. Engineering is about overcoming limits, not settling for them.

La Blue Pill STM32F103C8T6 corre a setenta y dos megahertz con arquitectura ARM Cortex-M3 de treinta y dos bits, tiene veinte kilobytes de RAM contra los dos del Arduino Uno, diecisรฉis canales ADC de doce bits, tres UART, dos SPI, dos I2C y CAN bus. Todo eso por dos dรณlares cuando un Arduino Uno oficial cuesta veinte. El problema es que no trae programador incluido, necesitas un ST-Link V2 externo, y si no aprendes a configurar sus registros correctamente no hace absolutamente nada. No es para principiantes, es para quienes ya dominaron el Arduino y quieren subir de nivel en sistemas embebidos reales. โก #electronica #STM32 #BluePill #ingenieria #embebidos
