Introduction:
In a world where technology keeps getting better, even opening doors is getting a high-tech makeover. Picture this: you use your phone or computer to unlock doors, super safe and easy. Today, we’re talking about smart door access. Django, a powerful web tool, and Arduino, a tiny computer, team up to change how we open doors. Welcome to the Smart Door Access: Django & Arduino Project.
Smart Door Access: A Tale of Innovation
Gone are the days of juggling keys or fumbling with passcodes. Smart door access systems bring convenience and security to the forefront, offering remote management, real-time monitoring, and cutting-edge authentication features. But how do we bring this vision to life?
Introducing Django and Arduino Integration
Enter Django, the wizard behind the web, providing a robust platform for user authentication and access control. Paired with Arduino, the Swiss Army knife of hardware tinkering, we create a seamless connection between the digital and physical realms, making our smart door dreams a reality.
Peeking into the Toolbox: Key Components
- Django Web Application: Think of Django as the conductor of our smart door symphony. It orchestrates user authentication, access permissions, and system monitoring through a sleek web interface.
- Arduino Microcontroller: Meet Arduino, the magician behind the scenes. It translates Django’s commands into tangible actions, controlling the electronic door lock with finesse.
- Electronic Door Lock: Our door lock, wired to the Arduino, dances to Django’s tune, opening and closing with precision based on user permissions.
Unleashing the Power: Benefits Galore
- Fortified Security: Django’s robust authentication ensures only the right folks get in, while Arduino ensures the door obeys only the rightful commands.
- Anywhere, Anytime Access: With Django’s web interface, administrators manage access from their cozy office or the beach, thanks to Arduino’s real-time responsiveness.
- Peace of Mind: Real-time monitoring means knowing who’s coming and going, providing invaluable peace of mind for security-conscious minds.
- Tailored Solutions: The modular nature of Django and Arduino allows for custom solutions, whether it’s a cozy apartment or a bustling office complex.

Django Views (views.py):
from django.shortcuts import render, redirect
from django.contrib.auth import authenticate, login
from django.http import HttpResponse
import serial
from django.contrib.auth import logout
# Replace 'COM5' with the correct port where the Arduino is connected
ser = serial.Serial('COM5', 9600, timeout=1)
def login_view(request):
if request.method == 'POST':
username = request.POST['username']
password = request.POST['password']
user = authenticate(request, username=username, password=password)
if user is not None:
login(request, user)
# Send 'O' command to open the door
ser.write(b'O')
return render(request, 'door_opened.html')
else:
return render(request, 'invalid.html')
return render(request, 'login.html')

logout(request)
return redirect('login_view')Arduino Code:
#include <Servo.h>

void setup() {
myServo.attach(9); // Attach the servo on pin 9 to the servo object

Serial.println("System ready. Send 'O' to open the door and 'C' to close the door.");
}
void loop() {
if (Serial.available() > 0) {
char command = Serial.read();
if (command == 'O') {
openDoor();
} else if (command == 'C') {
closeDoor();
} else {
Serial.println("Invalid command. Use 'O' to open and 'C' to close.");
}
}
}
// Function to open the door
void openDoor() {
Serial.println("Opening door...");
for (int pos = 0; pos <= 90; pos += 1) { // Move from 0 to 90 degrees
myServo.write(pos); // Tell servo to go to position in variable 'pos'
delay(10); // Wait 10 milliseconds between each degree
}
Serial.println("Door opened.");
}
// Function to close the door
void closeDoor() {
Serial.println("Closing door...");
for (int pos = 90; pos >= 0; pos -= 1) { // Move from 90 to 0 degrees
myServo.write(pos); // Tell servo to go to position in variable 'pos'
