Tutorial: Smart Home Lighting Simulation w/Arduino Uno, HC05 Bluetooth Module, mBlock 3 & Android Smartphone

This tutorial guides you through creating a smart home lighting system using Arduino and an Android phone. It covers the components needed, wiring the setup, installing the Android app, programming the Arduino, and testing the system. The project involves using an Arduino Uno, LEDs, resistors, and a Bluetooth module to control lights via a smartphone app.

What is the primary function of the Arduino Bluetooth controller app in this project?

• To provide power to the Arduino board

• To interface the Arduino with an Android phone

• To replace the Arduino board

• To control the Arduino board directly

Which component is used to connect the Arduino board to the Android phone?

• Wi-Fi module

• HC05 Bluetooth module

• USB cable

• Ethernet cable

What is the purpose of the resistors in the circuit?

• To limit the current to the LEDs

• To increase the voltage

• To power the Arduino board

• To connect the Bluetooth module

Which app is recommended for controlling the Arduino via Bluetooth on an Android device?

• Arduino Remote

• Arduino IDE

• SA Tech app

• Bluetooth Terminal

What is the first step in programming the Arduino board for this project?

• Setting up variables for the lights

• Connecting the board to a power source

• Installing the Bluetooth module

• Downloading the Arduino IDE

Which variable name is used for the light connected to pin 5?

• Bedroom

• Kitchen

• Living room

• Dining room

What should you do if the Arduino board does not upload the program?

• Reinstall the Arduino IDE

• Restart the computer

• Disconnect the RX pin

• Check the power supply

How can you test if the Bluetooth module is working correctly?

• By checking the LED lights

• By using a multimeter

• By observing the power light

• By connecting to the terminal

What number should be sent to turn on all the lights?

• 1

• 4

• 9

• 0

Why is it recommended to use buttons instead of the terminal for controlling the lights?

• Buttons are more reliable

• Buttons are easier to use

• Buttons are faster to set up

• Buttons are more secure
