This custom PCB is an interactive hardware simulator of Sofia Metro Line M2. Powered via a 5V USB-C connector, it uses an ATtiny85 microcontroller to drive 12 addressable WS2812B RGB LEDs arranged along the route map. It visually simulates real-time train movement, station stops, and transit flow along the metro line on a compact, custom-routed board.
