Introduction:
Imagine being able to control your home appliances directly from your smartphone! With the completion of our Bluetooth-controlled Arduino home automation project, you can manage devices like lights and fans wirelessly. This DIY project is an ideal starting point for beginners interested in home automation and IoT.
Project Overview:
In this project, we created a home automation system using an Arduino Uno, HC-05 Bluetooth module, and a 4-channel relay. The setup allows control over two bulbs and two fans, all operated via a mobile app through Bluetooth. Here’s a breakdown of the main components and how they work together.
Components Used:
- Arduino Uno - The main microcontroller board to control the system.
- HC-05 Bluetooth Module - Connects the system to your smartphone.
- 4-Channel Relay Module - Allows switching between four different devices.
- Light Bulbs & Fans - Our selected appliances to control wirelessly.
How It Works:
The HC-05 Bluetooth module establishes a connection between the Arduino and a smartphone app, enabling wireless control of connected appliances. When a command is sent from the smartphone, the Arduino triggers the appropriate relay to power on or off the selected appliance.
Step-by-Step Highlights:
- Wiring & Setup: Components were connected with care to ensure stability and safety.
- Programming: We programmed the Arduino to receive and interpret Bluetooth commands, switching appliances on or off.
- Testing: After assembling, each command was tested to verify seamless operation.
Learning Outcomes:
This project taught us a lot about Bluetooth communication, Arduino programming, and relay integration for power control. It’s a perfect example of how you can take the first step toward home automation with a DIY mindset.
Next Steps:
Consider expanding this project by adding sensors for automation based on conditions like temperature or time. With more components, you can create a fully integrated smart home system!
