Wiring and Setup

The key to building a functional voice controller for lights, fan, and robot is proper wiring and setup. Follow these steps:

  1. TX Pin of Bluetooth ModulePin 2 of Arduino (RX)
    RX Pin of Bluetooth ModulePin 3 of Arduino (TX)
    VCC Pin of Bluetooth Module5V Pin of Arduino
    GND Pin of Bluetooth ModuleGND Pin of Arduinoodule:
  2. Connect Relays for Appliances:
    • Use relay modules to connect lights, fans, and other devices to the microcontroller.
    • Ensure that high-power devices are safely isolated using optocouplers in the relays.
  3. Integrate an LCD Display:
    • Connect the SDA and SCL pins of the LCD to the microcontroller for I2C communication.

Programming Your Voice Controller

The following Arduino code is an example of how you can implement a voice controller for lights, fan, and robot. This code uses a Bluetooth module to receive commands and an LCD to display feedback.

#include <SoftwareSerial.h>

// Define the Bluetooth serial port
SoftwareSerial BTSerial(2, 3); // RX, TX pins for Bluetooth

void setup() {
  // Start the built-in serial communication for debugging
  Serial.begin(9600);

  // Start Bluetooth communication
  BTSerial.begin(9600);

  // Debugging message
  Serial.println("Bluetooth communication started...");
  Serial.println("Waiting for messages...");
}

void loop() {
  // Check if there is any data received from the phone (Bluetooth)
  if (BTSerial.available()) {
    // Read the incoming data
    String receivedMessage = BTSerial.readString();

    // Print the received message for debugging
    Serial.print("Received message: ");
    Serial.println(receivedMessage);

    // Trim the received message
    receivedMessage.trim(); // Remove extra spaces or newline characters

    // Respond to specific messages
    if (receivedMessage == "light on") {
      BTSerial.println("Turning on the light.");
      Serial.println("Replied: Turning on the light.");
      // Add logic to turn on the light
    } else if (receivedMessage == "fan on") {
      BTSerial.println("Turning on the fan.");
      Serial.println("Replied: Turning on the fan.");
      // Add logic to turn on the fan
    } else if (receivedMessage == "robot forward") {
      BTSerial.println("Robot moving forward.");
      Serial.println("Replied: Robot moving forward.");
      // Add logic to move the robot forward
    } else {
      // Default response for unrecognized messages
      BTSerial.println("I don't understand.");
      Serial.println("Replied: I don't understand.");
    }
  }

  // Add a small delay to avoid overloading the serial buffer
  delay(100);
}

How It Works

  1. Bluetooth Receives Commands:
    When you speak a command like “light on” or “fan on,” the Bluetooth module transmits the data to the microcontroller.
  2. Command Processing:
    The microcontroller matches the received command with predefined actions. For instance, the command “light on” activates the relay connected to the light.
  3. Data Display:
    The system provides real-time feedback on an LCD screen. For example, when the light is turned on, the screen displays, “Light is ON.”
  4. Action Execution:
    Appliances or devices respond to the voice commands, providing a seamless control experience.
