MRC_DJango

Prerequisites

• Python 3.x
• pip
• Arduino IDE
• MySQL Server

Setup

1. Clone the repository:

   git clone https://github.com/your-repo/MRC_DJango.git
   cd MRC_DJango/mysite

2. Create and activate a virtual environment:

   python3 -m venv venv
   source venv/bin/activate

3. Install the dependencies:

   pip install -r requirements.txt

4. Create a .env file in the root of your project and add your database credentials:

   MYSQL_DATABASE=django
   MYSQL_USER=root
   MYSQL_PASSWORD=2023
   MYSQL_HOST=localhost
   MYSQL_PORT=3306

5. Configure the database settings in mysite/settings.py:

   import os
   from dotenv import load_dotenv
   
   # Load environment variables from .env file
   load_dotenv()
   
   DATABASES = {
       "default": {
           "ENGINE": "django.db.backends.mysql",
           "NAME": os.getenv("MYSQL_DATABASE"),
           "USER": os.getenv("MYSQL_USER"),
           "PASSWORD": os.getenv("MYSQL_PASSWORD"),
           "HOST": os.getenv("MYSQL_HOST"),
           "PORT": os.getenv("MYSQL_PORT"),
       }
   }

6. Run the migrations:

   python3 manage.py makemigrations
   python3 manage.py migrate

7. Create a superuser for the Django admin:

   python3 manage.py createsuperuser

8. Start the Django development server:

   python3 manage.py runserver

9. Access the Django admin interface:

   Open your browser and go to http://localhost:8000/admin and log in with the superuser credentials.

Arduino Setup

1. Connect your Arduino to your computer and open the Arduino IDE.

2. Open the arduino_side/arduino.ino file in the Arduino IDE.

3. Upload the code to your Arduino.

Communication Process

From Arduino to Django

1. Arduino collects sensor data and sends it via HTTP POST requests to the Django API.

2. Django's API receives the data and stores it in the database.

Django API Endpoints

• BlogPost API:

  • GET /api/blogposts/ - List all blog posts
  • POST /api/blogposts/ - Create a new blog post
  • GET /api/blogposts/{id}/ - Retrieve a blog post
  • PUT /api/blogposts/{id}/ - Update a blog post
  • DELETE /api/blogposts/{id}/ - Delete a blog post

• Sensors API:

  • GET /api/sensors/ - List all sensors
  • POST /api/sensors/ - Create a new sensor
  • GET /api/sensors/{id}/ - Retrieve a sensor
  • PUT /api/sensors/{id}/ - Update a sensor
  • DELETE /api/sensors/{id}/ - Delete a sensor

• SensorData API:

  • GET /api/sensordata/ - List all sensor data
  • POST /api/sensordata/ - Create new sensor data
  • GET /api/sensordata/{id}/ - Retrieve sensor data
  • PUT /api/sensordata/{id}/ - Update sensor data
  • DELETE /api/sensordata/{id}/ - Delete sensor data

Configuration

Database Settings

The database settings are configured to use MySQL and are defined in mysite/settings.py:

import os
from dotenv import load_dotenv

# Load environment variables from .env file
load_dotenv()

DATABASES = {
    "default": {
        "ENGINE": "django.db.backends.mysql",
        "NAME": os.getenv("MYSQL_DATABASE"),
        "USER": os.getenv("MYSQL_USER"),
        "PASSWORD": os.getenv("MYSQL_PASSWORD"),
        "HOST": os.getenv("MYSQL_HOST"),
        "PORT": os.getenv("MYSQL_PORT"),
    }
}
