Hardware-Based Password Generator using BBC micro:bit and Python | Project Idea

Описание: In this video I demonstrate a complete hardware + software cybersecurity project where a BBC micro:bit is transformed into a hardware-assisted password generator using real sensor data and a Python desktop application. The micro:bit uses timing and accelerometer motion as entropy sources to generate strong random passwords, and streams live sensor telemetry and generation events to a Windows PC over USB serial. On the PC side, a custom Python GUI visualizes the system with a virtual micro:bit, live accelerometer graphs, generation state animation, and a slow cinematic password reveal with automatic strength analysis and clipboard copy. This project demonstrates important cybersecurity concepts such as entropy, randomness, human-in-the-loop security, hardware-assisted key generation, and secure password design in an educational and visual way. The full system is built using MicroPython on the micro:bit and Python with Tkinter and PySerial on Windows. This makes it ideal as a university project, final year project, cybersecurity lab demo, or embedded systems + software integration showcase. In this video I explain the hardware, the embedded code, the desktop software architecture, the serial protocol, and show the system working live. This is a prototype and learning tool, not a production cryptographic device, but it clearly demonstrates how hardware sensors can contribute to randomness and how security concepts can be visualized in real time.
