# LARA - Arduino Domotic Assistant



This project is a **Smart Domotic Assistant** that uses **Arduino** and a **Bluetooth module** to control a domotic house. As part of this project, the house was entirely **3D printed**, and the Arduino connections were **hand-wired**. The application provides speech-based control of various home appliances using an **Android application**.



---



## Features



- **Speech Control**: The assistant responds to spoken commands to control home appliances.

- **Bluetooth Communication**: Connects to an Arduino via Bluetooth for seamless operation.

- **Customizable Responses**: Predefined commands trigger specific actions and verbal acknowledgments.

- **3D Printed Model**: A miniature representation of a smart home for demonstration purposes.

- **Real-Time Feedback**: Provides real-time responses, including gas detection and temperature updates.

## Project Structure



### Android Application

- **Speech-to-Text**: Converts user speech into text to interpret commands.

- **Text-to-Speech**: Provides voice feedback based on system actions.

- **Bluetooth Communication**:

  - Establishes a connection with the Arduino using the **Bluetooth MAC address**.

  - Sends commands to control appliances.

  - Receives data (e.g., temperature or gas levels).



### Arduino Setup

- **Bluetooth Module**: HC-05/HC-06 or compatible module for wireless communication.

- **Hand-Wired Connections**: Manual wiring to interface the Arduino with LEDs, fans, or other appliances.

- **Command Handling**: Receives predefined commands (e.g., `salottoOn`) and triggers the respective relays or modules.

## Commands Overview



### Lights

- **Kitchen**:  

  - `Accendi la luce in cucina` → Turns on the kitchen light.  

  - `Spegni la luce in cucina` → Turns off the kitchen light.

- **Living Room**:  

  - `Accendi la luce in salotto` → Turns on the living room light.  

  - `Spegni la luce in salotto` → Turns off the living room light.



### Heating and Cooling

- **Heater**:  

  - `Accendi la stufa` or `Fa freddo` → Turns on the heater.  

  - `Spegni la stufa` or `Fa caldo` → Turns off the heater.

- **Fan**:  

  - `Accendi il ventilatore` → Turns on the fan.  

  - `Spegni il ventilatore` → Turns off the fan.



### Sensors

- **Temperature**: `Quanti gradi ci sono` → Reads and announces the current temperature.  

- **Gas Detection**: Provides warnings if hazardous gas levels are detected.



### Greetings

- `Ciao` → Responds with "Ciao anche a te".  

- `Come ti chiami` → Responds with "Mi chiamo Lara".

## Technical Highlights



1. **Speech Recognition**:

   - Utilizes the `SpeechRecognizer` API for free-form voice command recognition.

   - Listens for specific phrases mapped to corresponding actions.



2. **Text-to-Speech**:

   - Implements `TextToSpeech` to provide auditory feedback.

   - Configured for **Italian language** responses.



3. **Bluetooth Communication**:

   - Sets up a secure socket connection using the device's MAC address.

   - Employs separate threads for sending and receiving data to avoid blocking the UI thread.



4. **Gas Detection**:

   - Uses a periodic handler to monitor incoming gas levels via the Arduino and alerts the user.

## How to Use



1. **Setup Arduino**:

   - Connect the Bluetooth module to the Arduino.

   - Program the Arduino to handle commands such as `cameraOn` or `stufaOff`.



2. **Prepare the Android App**:

   - Clone or download the project repository.

   - Build and run the app on an Android device.

   - Ensure Bluetooth is enabled and paired with the Arduino module.



3. **Control with Voice**:

   - Open the app, press the microphone button, and issue commands.

   - Example: Say *"Accendi la luce in salotto"* to turn on the living room light.

## Requirements



### Hardware

- **Arduino** (e.g., Uno, Mega)

- **Bluetooth Module** (e.g., HC-05)

- 3D printed house model with LEDs and relays

- Sensors for gas and temperature monitoring



### Software

- Android device with Bluetooth capability

- Android Studio for building the app

- Arduino IDE for programming the microcontroller
