Aim

To design and implement a Bluetooth-based remote access system using ESP32 for controlling a buzzer wirelessly through a mobile device.

Requirements

Hardware Components

• ESP32 development board

• Buzzer

• Connecting wires

• Breadboard

• Android mobile phone with Bluetooth support

Software Requirements

• Arduino IDE

• ESP32 board package

• Bluetooth terminal application

Procedure

1. Install the Arduino IDE and configure the ESP32 board manager.

2. Connect the buzzer to the ESP32 board using suitable GPIO pins and ground connection.

3. Open the Arduino IDE and create a new program for Bluetooth communication.

4. Include the BluetoothSerial library in the program to enable wireless communication.

5. Initialize the Bluetooth device with a unique name for pairing with the mobile phone.

6. Write the logic to receive commands from the Bluetooth terminal application.

7. Program the ESP32 so that when the command “on” is received, the buzzer turns ON.

8. Similarly, when the command “off” is received, the buzzer turns OFF.

9. Compile and upload the program to the ESP32 board.

10. Pair the mobile phone with the ESP32 Bluetooth device.

11. Open the Bluetooth terminal application and send commands to test the buzzer operation.

12. Observe the response of the buzzer for different commands.

Result

The Bluetooth-based remote access system was successfully implemented using ESP32. The buzzer was controlled wirelessly through a mobile phone by sending ON and OFF commands via Bluetooth communication.
