The Whack-a-Mole game simulates a carnival-style game where players score points by hitting randomly flashing moles (represented by LEDs) using push buttons. The game includes:
- A scoring system
- A timer
- Sound effects to enhance user interaction
The following components were used to build the circuit:
| Component | Quantity |
|---|---|
| 555 Timer IC | 2 |
| Resistors (10kΩ, 1kΩ, 100kΩ) | 6 total |
| Capacitors (1nF, 100mF, 80mF) | 3 total |
| NAND-based D-Latch | 1 |
| 4013 D-Flip Flop | 2 |
| Up/Down Counter IC (4510) | 4 |
| BCD to 7-Segment Display | 4 |
| Decoder/Display Driver (7447) | 1 |
| Logic Gates (NOT, AND, NOR, OR, XNOR) | Multiple |
| Push Buttons | 12 |
| LEDs | 11 |
| 74LS112 JK-Flip Flop | 3 |
| Decoder IC (74HC238) | 1 |
| Battery (5V output) | 1 |
| Buzzer | 1 |
| Breadboards | 5 |
The circuit design integrates various digital logic components to create the core functionality of the game.
- LEDs represent the moles
- Push buttons allow scoring
- 555 timer and flip-flops control mole activation and scoring logic
- A display driver shows the player's score

The implementation follows these steps:
- Assembling the circuit on a breadboard.
- Connecting all components as per the schematic.
- Programming the logic for:
- Mole activation (random LED flashes)
- Scoring mechanism (hit detection)
- Game timing (30-second countdown)
- End-of-game buzzer activation
Rigorous testing was conducted to ensure:
- LEDs flashed randomly as expected.
- Scoring system correctly registered hits and misses.
- Timer functioned properly, ending the game after 30 seconds.
- The buzzer activated at the end of the game.
Debugging was performed iteratively during lab sessions to refine the circuit.
The Whack-a-Mole project successfully demonstrates Digital Logic Design principles through an engaging and interactive game. It provided an insightful learning experience in:
- Circuit design
- Flip-flop operations
- Counter logic
- Real-world implementation of logic gates
