Smart, low-power sensor hub for STM32F446RE with modular sensor APIs, dynamic power-mode sampling, cooperative scheduler, UART CLI, and full documentation.

This project demonstrates a Digital Stopwatch using the LPC2148 ARM7 Microcontroller. It uses a 4x4 keypad for start/stop/reset operations and displays elapsed time on a 16x2 LCD. It’s ideal for learning ARM timers, interrupt handling, and embedded application design

A rotating POV (Persistence of Vision) display built with ESP32 and APA102 LED strips, supporting image animations from flash or UDP streaming.
