🧩 Mini Projects Collection

This repository contains a curated set of small-scale projects and academic experiments developed as part of my learning journey in computer science. Each subproject demonstrates a specific concept — from basic I/O and GUI design to digital logic, data structures, embedded systems, and low-level assembly programming.

These projects span multiple languages including C, Python, Verilog, Solidity, ARM Assembly, and Arduino, and are organized for easy exploration and reuse.
