Meet Micro Albert, a pocket-sized quadruped robot powered by an ESP32-C3, four SG90 servos, and a tiny OLED display. It can walk, sit, wave, shake hands, display the time and weather, and even show my live YouTube subscriber count over Wi-Fi. In this video I show: โข How I redesigned my full-size Albert robot into a miniature version โข The ESP32-C3 electronics and custom shield โข A simple USB-C rechargeable battery hack using a recycled power bank โข 3D printing and assembly steps โข Servo calibration and firmware upload โข Live data features and serial commands Everything is completely open source: โ Firmware โ STL files โ Wiring diagrams โ Bill of Materials โ Assembly instructions ๐ GitHub repository: link here If you build your own Micro Albert, post a picture in the commentsโIโd love to see your version.

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
