MISSION-TIMER

This repository contains firmware for a mission timer, designed to showcase state machine implementation using a custom FSM framework. Upon activation, the timer enters a countdown state, during which a red LED blinks to indicate status. The system supports real-time defusal, allowing transition to a safe state at any point before completion. Upon reaching zero, the timer executes a predefined terminal event.
