Arduino Unity 2D/3D Interaction

This Unity project seamlessly integrates Arduino hardware with both 2D and 3D environments to create an interactive gaming experience. By using an Arduino Uno, a few jumper wires, and a membrane keyboard as a touch button, this project enables you to control in-game actions using real-world inputs. When a key is pressed on the membrane keyboard, a corresponding serial message is sent to the Unity console, allowing for direct interaction with Arduino-controlled devices.

The successful connection between Arduino and Unity is achieved through the Ardity asset, which can be downloaded from the provided link.

Features

• Arduino Integration: Use Arduino Uno and a membrane keyboard as a touch button to trigger in-game events.

• Serial Communication: Receive serial messages in Unity, enabling real-time interaction with Arduino-controlled hardware.

• 2D and 3D Environments: This project offers compatibility with both 2D and 3D Unity environments, providing flexibility for different types of games and simulations.

• Gameplay Element: The project includes a 2D scene with a falling game object (square) that responds to keyboard inputs from the Arduino. When the designated key is pressed, the game logic executes a series of if statements to determine if the object should be destroyedThe Scrip, awarding points to the player. If the player fails to act in time, the object is automatically removed from the game at a specific y-axis location.

Getting Started

To get started with this project, follow these steps:

1. Hardware Setup: Connect your Arduino Uno and the membrane keyboard to your computer using USB cables and jumper wires as per your specific hardware requirements.

2. Ardity Installation: Download and import the Ardity asset into your Unity project from this link. Follow the installation instructions provided on the Ardity website to establish a successful connection between Arduino and Unity.

3. Open the Project: Open the Unity project included in this repository.

4. Scene Setup: Examine the 2D scene provided, which contains a falling game object (square). Customize this scene or replace it with your own game elements as needed.

5. Arduino Configuration: Modify the Arduino code to map key presses on the membrane keyboard to specific serial messages that Unity can understand and act upon.

6. Unity Interaction: Implement and customize the Unity scripts responsible for detecting serial messages and executing game logic based on user input from the Arduino.

7. Testing: Run the Unity project and test the interaction between the Arduino hardware and the game object. Ensure that pressing the designated key on the membrane keyboard triggers the desired in-game actions.

Usage

This project serves as a foundation for creating interactive Unity experiences that incorporate Arduino hardware. You can extend and customize it to suit your specific gaming or simulation needs. #Code for MyListener.cs
