📝 Description
This project transforms your Arduino board into a minimalist handheld console. By leveraging the Arduino_LED_Matrix library, the game manages ball physics, collision detection with walls and paddles, and a scoring system displayed via the Serial Monitor.
Key Features:
- Integrated Display: No external modules required; it uses the native 12×8 LED matrix.
- Local Multiplayer: Two-player support using 4 external pushbuttons.
- Dynamic Difficulty: The ball speed periodically increases to keep the gameplay challenging.
- Real-time Scoring: Points are tracked and sent via Serial (9600 baud).
🛠️ Hardware Requirements
- Board: Arduino UNO R4 WiFi.
- Buttons: 4x Momentary Pushbuttons.
- Resistors: Not required (uses internal INPUT_PULLUP).
- Breadboard & Jumper wires.
🖮 Pinout Configuration
Component Arduino Pin Function
- P1 Button Up D13 Moves Left Paddle Up
- P1 Button Down D12 Moves Left Paddle Down
- P2 Button Up D11 Moves Right Paddle Up
- P2 Button Down D10 Moves Right Paddle Down
- Common GND GND Ground for all buttons
🕹️ Game Logic
- Bouncing: When the ball hits a paddle, the X direction is reversed and the hits counter increases.
- Speed Scaling: Every 6 successful hits (hits >= 6), the loop_delay decreases by 20ms, speeding up the action until a minimum limit of 80ms is reached.
- Scoring: If a player misses the ball, the opponent scores a point. The ball then resets to the center with a randomized direction.
🛠️ Development
This project includes a Makefile to automate the workflow using arduino-cli.
Prerequisites
- Arduino CLI installed.
- Arduino UNO R4 core installed:
arduino-cli core install arduino:renesas_uno
