A fun and interactive 3x3 LED game built with Arduino Nano, where each of the 9 LEDs on the display acts as a button. The game’s objective is simple yet challenging: invert the LEDs in such a way that all of them are turned on simultaneously!
The game features a 3x3 grid of LEDs, each of which can be toggled between ON and OFF states. When a button is pressed (corresponding to a specific LED), it inverts its own state and also inverts the state of nearby LEDs based on its position. The challenge is to strategically press the buttons to turn all the LEDs ON.
The buttons are numbered as follows:
| 0 | 1 | 2 |
|---|
| 3 | 4 | 5 |
|---|
| 6 | 7 | 8 |
|---|
When a button is pressed, the corresponding LEDs are toggled as follows:
- Button 0: Inverts LEDs 0, 1, 3, 4
- Button 1: Inverts LEDs 0, 1, 2
- Button 2: Inverts LEDs 1, 2, 4, 5
- Button 3: Inverts LEDs 0, 3, 6
- Button 4: Inverts LEDs 1, 3, 4, 5, 7
- Button 5: Inverts LEDs 2, 5, 8
- Button 6: Inverts LEDs 3, 4, 6, 7
- Button 7: Inverts LEDs 6, 7, 8
- Button 8: Inverts LEDs 4, 5, 7, 8
- Corner Buttons (0, 2, 6, 8) invert themselves plus all the adjacent buttons.
- Middle-Side Buttons (1, 3, 5, 7) invert themselves plus the adjacent corner buttons.
- Center Button (4) inverts itself, plus the adjacent middle-side buttons.
The goal is to press the buttons in such a way that all 9 LEDs are ON at the same time. When this happens, the game plays a victory sound, and the player can start a new random game.
