Study Notes

Smart Home Overview

A smart home integrates technology to enhance safety, convenience, comfort, and aesthetics.
It uses sensor modules, programming, and laser-cutting technology to create automation.
It aims to help users understand the characteristics and principles of sensors, learn Arduino programming, and use sensors to automate home equipment.
The course uses Arduino open-source hardware to create a smart home model.

Advantages of a Smart Home

Intellectualization: Furniture becomes actively intelligent, shifting from passive static structures.
Informatization: Provides information exchange functions to facilitate communication with the outside world.
Humanization: Emphasizes coordination between people and their living environment, allowing users to control their indoor living spaces.
Energy-saving: Automated control of household appliances enables power saving and energy efficiency.

The Arduino Mainboard

A revolutionary product combining Bluetooth 4.0 protocol and Arduino UNO R3 functionality.
Fully compatible with traditional Arduino UNO mainboard and Arduino IDE.
Features a 2.4GHZ operating frequency band, GFSK modulation mode, 0 dB maximum transmitting power, and up to 50 meters maximum transmitting distance.
Utilizes a TI CC2540 chip, supporting user modification and viewing of device name, service UUID, transmit power, pairing password, and other instructions.
Mobile apps for Android and iOS enable quick development of mobile communication hardware devices.
Supports USB virtual serial port, hardware serial port, and three-way transmission modes.
Offers master-slave switching, Bluetooth automatic connection to slaves in host mode, and transmission of data packets over 20 bytes.
Compatible with Arduino expansion boards, sensors, motors, and steering gear drivers.

Arduino IDE

Software-editing environment for Arduino products, used to write and upload code.
Downloadable from Arduino's official website: https://www.arduino.cc/en/software.

Driver Installation

Requires the installation of a driver to connect the Arduino board to the computer.
In Windows 10, the driver may be automatically downloaded, but in Windows 7, manual installation is often required.
To manually installing the driver, access the "drivers" folder in the "Documents" folder.

Arduino IDE Interface

Provides features for verification, uploading, creating new files, opening files, saving files, and accessing the serial monitor.
Offers example programs for beginners located under the "examples" folder or through File > Examples.

Smart Home Program

Requires connecting the Arduino board to the computer via USB.
Input the desired sample program to initiate the Smart Home program.
