# Happy-Smart-Home-PIC16f877A
## 📃Description
This is a project for a smart home system using PIC16f877A microcontroller. The system is designed to control home for ease of life and happiness. The system includes an RFID-based door lock, fire alarm system, theft detection system with laser security with alarm, screen status display, and indication of status with LEDs. That was done as a project for the Data Aquistion Course at the Faculty of Computer Engineering, AASTMT - Cairo 2024.
## 💪Features
- RFID based door lock
- Fire alarm system
- Theft detection system with laser security with alarm
- Screen status display
- Indication of status with LEDs

## 🏡Body Design
The body is designed in Autocad and cut using a laser cutting machine. The body is designed to hold all the components in place and provide a good look for the system. The material used is MDF 3mm thickness. [Here](https://github.com/AntonAshraf/Smart-Home-PIC16f877A/blob/main/Design%20Autocad.DWG) is the AutoCAD design for the body.
## ⚙️Working Scenario
Let's dive into the working scenario of the system and see how it works in different situations.
### Scenario 1: RFID-based door lock
- The system will be in the locked state initially.
- When the RFID card is scanned, the system will check the card number with the stored card number.
- If the card number matches, the system will unlock the door using a servo, show the card number on the LCD display, buzzer accepted tone, and turn on the green LED.
- If the card number does not match, the system will show the card number on the LCD display, buzzer rejected tone, and turn on the red LED.

---
### 🔥Scenario 2: Fire alarm system
- The system will continuously check the fire sensor.
- If the fire sensor detects a fire, the system will show the fire detected message on the LCD display, turn on the blue LED, turn on the fan using relay, and buzzer fire alarm tone.

---
### 😈Scenario 3: Theft detection system with laser security with alarm
- The system will continuously check the LDR sensor.
- If the LDR sensor detects any interruption in the laser beam, the system will show the theft detected message on the LCD "Theft detected, Call 911", turn on all LEDs blinking, and buzzer theft alarm tone.
