        Usage

        • Gather the necessary components: HC-05 Wireless Bluetooth RF Transceiver Module, power supply (3.6V to 6V), microcontroller or Arduino board, and jumper wires.
        • Identify the power supply requirements of the HC-05 module and prepare the appropriate power source.
        • Take the HC-05 module and locate the six-pin header. The pins are usually labeled as VCC, GND, TXD, RXD, STATE, and KEY.
        • Connect the VCC pin of the module to the positive terminal of the power supply.
        • Connect the GND pin of the module to the negative terminal of the power supply.
        • Connect the TXD pin of the module to the RX pin of the microcontroller or the communication device using a jumper wire.
        • Connect the RXD pin of the module to the TX pin of the microcontroller or the communication device using a jumper wire.
        • Ensure that all the connections are secure and properly connected.
        • Power on the HC-05 module by supplying power to the VCC and GND pins.
        • By default, the module is in AT command mode. To enter the command mode, keep the KEY pin high (connected to VCC) while powering on the module.
        • Set up the microcontroller or Arduino board to communicate with the HC-05 module using the UART/Serial interface.
        • Configure the baud rate of the microcontroller or Arduino board to match the default baud rate of the HC-05 module (usually 9600 bps).
        • Once the module is powered on and the microcontroller or Arduino board is ready, you can start sending and receiving data wirelessly using Bluetooth.
        • Use the appropriate Bluetooth software on your device (e.g., a smartphone or computer) to search for available Bluetooth devices.
        • The HC-05 module should appear in the list of available devices with the default Bluetooth name (HC-05). Pair and connect to the module using the default PIN (1234).
        • Once the connection is established, you can send and receive data between the microcontroller or Arduino board and the Bluetooth device.
