Module HC-05 Bluetooth

Description

The HC-05 is a widely used Bluetooth module known for its ease of use and compatibility with microcontrollers like the Arduino. It allows wireless communication between devices over short distances using the Bluetooth protocol. Here are the key features and details of the HC-05 Bluetooth module:

1. **Bluetooth Version:** The HC-05 module is typically based on Bluetooth 2.0 (EDR – Enhanced Data Rate) or Bluetooth 2.1 (EDR) technology. It supports the Serial Port Profile (SPP) for serial communication.

2. **Operating Modes:** The HC-05 module can be configured to operate in either Master or Slave mode, making it suitable for various applications. In Master mode, it can initiate connections, while in Slave mode, it can accept incoming connections.

3. **Serial Communication:** The module uses UART (Universal Asynchronous Receiver-Transmitter) for serial communication, making it easy to connect to microcontrollers and other devices.

4. **Voltage Requirements:** The module typically operates on 3.3V, but it can accept 5V serial communication. You need to be cautious about voltage compatibility when connecting it to different devices.

5. **Compatibility:** The HC-05 is compatible with a wide range of microcontrollers and devices, making it suitable for IoT (Internet of Things) and wireless communication projects.

6. **Communication Range:** The range of the HC-05 can vary based on environmental conditions, but it is generally designed for short-range communication, typically up to 10 meters (or about 33 feet).

7. **AT Commands:** The module can be configured and controlled using AT commands. These commands allow you to set the device name, pairing code, mode (Master or Slave), and other parameters.

8. **Applications:** The HC-05 module is used in a variety of applications, including wireless data transfer, remote control, Bluetooth speakers, Arduino-based projects, robotics, and more.

9. **Pairing:** In most applications, you need to pair the HC-05 module with another Bluetooth device for secure and reliable communication.

10. **LED Indicators:** Many HC-05 modules have LED indicators to show the module’s power status and Bluetooth connectivity.

11. **Libraries and Code:** For microcontroller projects, libraries and example code are available for popular platforms like Arduino, making it relatively easy to get started with the HC-05.

The HC-05 Bluetooth module is a cost-effective and versatile solution for adding wireless communication capabilities to your electronics projects. It’s commonly used for creating remote-controlled devices, Bluetooth-enabled sensors, and wireless data transmission between devices within a short range.
