  1. Connecting a Bluetooth module like the HC-05 to an Arduino enables wireless communication for controlling devices or exchanging data. Below are the steps to set up and use the HC-05 module with Arduino.

    Step 1: Required Components

    • Arduino Uno (or compatible board)

    • HC-05 Bluetooth Module

    • Jumper wires

    • Breadboard (optional)

    Step 2: Wiring the HC-05 to Arduino

    1. Power Connections: Connect the VCC pin of HC-05 to the 5V pin on Arduino. Connect the GND pin of HC-05 to the GND pin on Arduino.

    2. Data Connections: Connect the TXD pin of HC-05 to the RX (Pin 0) of Arduino. Connect the RXD pin of HC-05 to the TX (Pin 1) of Arduino. (Use a voltage divider for RXD if required, as it operates at 3.3V logic.)

    Step 3: Upload Code to Arduino

    Disconnect the TX and RX pins temporarily while uploading code to avoid interference. Below is an example code for basic communication:
