In this Project we will make “Bomb Puzzle Game” with Arduino. The “Bomb Puzzle Game” is an interactive game designed using Arduino Uno, a 4×4 keypad, a YX5300 MP3 module, and a TM1637 seven-segment display. The game consists of two sequential puzzles which user have to complete within predefined time limit:

1. Cable Puzzle: The player must insert wires into two holes with the correct configuration. If successful, a success sound is played, and the game progresses to the next puzzle.
2. Password Puzzle: The player must enter a predefined password using the keypad within a set time limit. If successful, a positive sound is played; otherwise, a “blast” sound is triggered.

Success triggers a positive sound, while failure results in a “Bomb Blast” sound effect, enhancing the game’s realism and excitement.

Components used in Bomb Puzzle Game:

1. Arduino Uno: The microcontroller to control the game logic.
2. 4×4 Keypad: Used for user input to enter the password.
3. YX5300 MP3 Module: Plays sound effects (e.g., success, failure and blast sounds).
4. TM1637 Seven-Segment Display: Displays the countdown timer.
5. Cable Puzzle Mechanism: Two input holes and wires for the first puzzle.
6. Speaker: Connected to the MP3 module for audio output.
7. Power Supply: To power the Arduino and peripherals.
8. Connecting Wires: For interfacing the components.
9. Resistors and Breadboard: For prototyping connections.

Project Work Flow:

1. Game Initialization:
   • The system initializes when powered on.
   • The TM1637 seven-segment display shows the countdown timer.
   • The YX5300 MP3 module plays a “game start” sound.
2. Cable Puzzle:
   • The player inserts wires into two designated holes.
   • The Arduino verifies the configuration using digital input pins.
   • If the configuration is correct, a success sound is played, and the game progresses to the password puzzle.
   • If incorrect, the player can retry until successful.
3. Password Puzzle:
   • The player enters a predefined password using the 4×4 keypad.
   • On Each keypress Tick sound is played.
4. Countdown Timer:
   • The timer counts down from a predefined time (e.g., 60 seconds).
   • The TM1637 display updates every second.
5. Password Validation:
   • If the correct password is entered within the time limit:
     • The timer stops.
     • The YX5300 MP3 module plays a success sound (e.g., “Success or defused”).
     • The game resets for another round.
   • If the time limit is exceeded:
     • The YX5300 MP3 module plays a blast sound.
     • The game resets for another round.
