The module operates as a slave device, meaning it can only be connected to a master device, such as a smartphone, tablet, or computer, which initiates the Bluetooth connection. Once paired, the HC-06 module allows bidirectional data transmission between the master device and the Arduino or other microcontroller.
The HC-06 module uses Bluetooth 2.0 technology, supporting the Serial Port Profile (SPP) for communication. It operates at a frequency of 2.4 GHz and offers a range of approximately 10 meters (depending on the environment and surrounding obstacles).
One of the key features of the HC-06 module is its simplicity of use. It requires minimal wiring and can be easily integrated into Arduino or other microcontroller projects. Additionally, it has a standard pinout configuration, making it compatible with various development boards.
Overall, the HC-06 Bluetooth module provides a cost-effective and straightforward solution for enabling wireless communication in your projects, allowing you to control and exchange data wirelessly with other Bluetooth-enabled devices.
Connect Bluetooth Module HC-06 to Arduino
To connect the HC-06 Bluetooth module to an Arduino Uno board, follow these steps:
1. Gather Components:
Gather the required components
- Arduino Uno board
- HC-06 Bluetooth module
- Jumper wires (male-to-female)
2. Identify Pins
Identify the pins on the HC-06 module:
- VCC: Connects to the 5V pin on the Arduino Uno
- GND: Connects to the GND pin on the Arduino Uno
- TXD: Connects to the RX (receive) pin on the Arduino Uno
- RXD: Connects to the TX (transmit) pin on the Arduino Uno
3. Make Connections
Make the connections between the HC-06 module and Arduino Uno as follows:
- Connect the VCC pin of the HC-06 module to the 5V pin on the Arduino Uno.
- Connect the GND pin of the HC-06 module to the GND pin on the Arduino Uno.
- Connect the TXD pin of the HC-06 module to the RX (receive) pin (pin 0) on the Arduino Uno.
- Connect the RXD pin of the HC-06 module to the TX (transmit) pin (pin 1) on the Arduino Uno.
4. Bluetooth Coding
Once the connections are made, you are ready to upload a sketch to the Arduino Uno that will allow you to communicate with the HC-06 module. Here is a sample code snippet to get you started:
#include <SoftwareSerial.h>
SoftwareSerial bluetooth(0, 1); // RX, TX
void setup() {
Serial.begin(9600);
bluetooth.begin(9600);
}
void loop() {
if (bluetooth.available()) {
char data = bluetooth.read();
Serial.print(data);
}
if (Serial.available()) {
char data = Serial.read();
bluetooth.print(data);
}
}
5. Upload the Bluetooth Sketch
Upload the code to the Arduino Uno using the Arduino IDE.
Open the Serial Monitor in the Arduino IDE to communicate with the HC-06 module. Set the baud rate to 9600 (or as per your module's configuration)
That's it! You have successfully connected the HC-06 Bluetooth module to the Arduino Uno board. You can now send and receive data wirelessly between your Arduino and any Bluetooth-enabled device paired with the HC-06 module.
