How it works
This project uses flip-flops to display the text TUAN9304 on a 7-segment display. The state table below describes the states, outputs, and next state logic:

How to test
- Reset: Press the reset button to initialize the state machine to state 0 (0000).
- Observation: Monitor the 7-segment display output. You should observe the sequence "Tuan9304" repeating or cycling.
- Verification: Check that each character is formed correctly according to standard 7-segment encoding (e.g., 'T' might be represented by a specific combination of segments, often simplified or stylized for 7-segment displays).
