Task 6.2: Finite-State Machine Model: Setminutesclock Sethoursclock

This document describes a finite-state machine model for a digital clock and alarm system. The system has states for setting the hours and minutes of the clock, setting the hours and minutes of the alarm, and an alarm state. Transitions between states are triggered by buttons on a rotary dial and joystick to increment, decrement, and select the time and alarm values. When the alarm time is reached and the alarm is enabled, it will trigger the alarm state.
