- Can be easily interfaced with the Arduino Nano using serial communication
Wiring HC-05 with Arduino Nano
To connect an HC-05 module to an Arduino Nano, use the following connection schema:
| HC-05 Pin | Arduino Nano Pin |
|---|---|
| VCC | 5V |
| GND | GND |
| TXD | RXD (D0) |
| RXD | TXD (D1) |
Programming Arduino Nano with HC-05
After wiring, you can code your Arduino Nano to communicate with the HC-05 module. The basic idea is to use the Serial library to send and receive data wirelessly.
“`cpp
include
SoftwareSerial BTSerial(10, 11); // RX | TX
void setup()
{
Serial.begin(9600); // Communication with PC
BTSerial.begin(9600); // Communication with HC-05
}
void loop()
{
if (BTSerial.available()) {
Serial.write(BTSerial.read());
}
if (Serial.available()) {
BTSerial.write(Serial.read());
}
}
“`
This snippet allows your Arduino Nano to send serial data to and from the HC-05 module.
2. HC-06 Bluetooth Module
For simpler projects, the HC-06 is another excellent Bluetooth module. It is primarily a slave device, making it perfect for basic applications:

- Slightly less versatile than HC-05 (master mode not supported)
Connecting HC-06 with Arduino Nano
The wiring setup is quite similar to the HC-05, as shown below:
| HC-06 Pin | Arduino Nano Pin |
|---|---|
| VCC | 5V |
| GND | GND |
| TXD | RXD (D0) |
| RXD | TXD (D1) |
Sample Code for HC-06
Using a similar approach, here’s a simple code example to get you started with the HC-06 module:
“`cpp
include
SoftwareSerial BTSerial(10, 11); // RX | TX
void setup()
{
Serial.begin(9600);
BTSerial.begin(9600);
}
void loop()
{
if (BTSerial.available()) {
Serial.write(BTSerial.read());
}
if (Serial.available()) {
BTSerial.write(Serial.read());
}
}
“`
This code sets up serial communication between the HC-06 and the Arduino Nano.
