Home Harmony is a home automation system. By leveraging the Arduino Uno microcontroller and integrating various sensors and controllers, this system enables comprehensive monitoring and control of different areas within a home.
- Motion Detection: Uses PIR (Passive Infrared) motion sensors to monitor environmental conditions and detect motion in real-time.
- Light Control: Adjusts lighting based on detected motion and user input, creating personalized and comfortable living spaces.
- Security Enhancements: Enhances home security by alerting users to potential intrusions through motion detection.
- User Interface: Interacts with the system using a 16x2 LCD, rotary encoders, and keypads to control light levels and view system status.
- Cost-Effective: Utilizes affordable components to make smart home technology accessible to a broader audience.
- Remote Access: Allows remote monitoring and control of the home environment.
- Microcontroller: Arduino Uno
- Sensors: PIR Motion Sensor
- Displays: SSD1306 OLED, 16x2 or 20x4 LCD
- Input Devices: Keypad, Rotary Encoders, Potentiometers
- LEDs: Standard and RGB LEDs
- Development Environment: WOKWI Online Emulator
- Programming Language: AVR C
The system integrates various hardware components with the Arduino Uno to monitor and control home environments. The key components and their functions are as follows:
- PIR Motion Sensor: Detects motion and triggers LED activation for a specified duration.
- RGB LED: Controlled by potentiometers to set the desired color intensity.
- LCD Display: Shows user inputs, system status, and motion alerts.
- Keypad: Allows users to set the duration for LED activation when motion is detected.

- Power on the Arduino Uno.
- Use the keypad to set the duration for LED activation.
- Adjust the RGB LED color using the potentiometers.
- Monitor the system status and motion alerts on the LCD display.
- Motion Detection: The PIR motion sensor will detect motion and activate the LED for the duration set by the user.
- Light Control: Adjust the RGB LED color using the potentiometers.
- User Interface: Use the keypad to set the LED activation duration and monitor the system status on the LCD display.
The system design involves integrating sensors, controllers, and user interface components to create a seamless smart home experience. The interactions between components are mapped out to ensure efficient and reliable operation.
The software is developed using AVR C within the WOKWI online emulator environment. Key functions include:
- Motion Detection: Reads data from PIR motion sensors and triggers LED activation.
- Light Control: Adjusts light intensity based on user input.
- User Interface: Handles user input from the keypad and displays system status on the LCD screen.
- System Initialization: Initializes all sensors, displays, and inputs when the system is powered on or reset.
The software is tested in the WOKWI emulator to simulate real-world conditions. This allows for validation of sensor readings, user interactions, and system responses. Issues identified during testing are addressed through iterative debugging and code refinement.
- Enhanced Remote Access: Implement remote control capabilities using IoT platforms.
- Additional Sensors: Integrate more sensors (e.g., temperature, humidity) for comprehensive home monitoring.
- Mobile App: Develop a mobile app for easier remote control and monitoring.
