Operation Flow

Start
  │
  ▼
[Initialize Registers] → Set constants, count = 0
  │
  ▼
[Main Loop]
  │
  ├─► [Display Count] → Show current count on screen
  │
  ├─► [LED Control] → Green (count < 10) / Red (count == 10)
  │
  ├─► [Button A Check] → If pressed and released:
  │       ├─► Not full → count++ → [Gate Action] → open/close gate
  │       └─► Full → [Gate Action] → open/close gate (still allow entry?)
  │
  ├─► [Button B Check] → If pressed and released:
  │       └─► count-- → [Gate Action] → open/close gate
  │
  └─► Loop back to display

Key Features

1. Debounce Handling: Each button waits for release before processing, preventing multiple triggers
2. Capacity Control: Library max capacity is 10 people (R12 = 10)
3. Visual Feedback: LED shows green when space available, red when full
4. Automatic Gate: Servo opens (90°) for 1 second, then closes (0°)
5. Digital Display: Shows current count as 2-digit number

Testing Scenarios

Action	Expected Result
Press Button A (count=0)	Count becomes 1, gate opens then closes, LED green
Press Button A (count=9)	Count becomes 10, gate opens then closes, LED red
Press Button A (count=10)	Gate opens then closes, count remains 10, LED red
Press Button B (count=1)	Count becomes 0, gate opens then closes, LED green
Press Button B (count=0)	Count remains 0, gate opens then closes, LED green
