HC-06 Module Application Ideas
- Wireless control of Arduino-based devices
- Bluetooth-enabled home automation systems
- Data logging and monitoring via Android apps
- Wireless programming and debugging interfaces
- Robotics and sensor networks for education and prototyping
HC-06 Pin Configuration
- VCC – Connect to 3.3V or 5V supply
- GND – Ground
- TXD – Module transmit, connect to microcontroller RX
- RXD – Module receive, connect to microcontroller TX (use level shifting if your MCU is 5V tolerant)
- State – LED/status output showing pairing and connection state
HC-06 Programming and Setup Guide
- Power the module (3.3V to 6V) and wait for the LED to indicate ready state.
- On your Android device or PC, enable Bluetooth and scan for devices. Pair with the HC-06 (default PIN often 1234 or 0000).
- Use any Bluetooth terminal app or Serial Monitor to connect. Default baud is 9600. Change baud via AT commands if needed.
- In Arduino sketches, use SoftwareSerial or a hardware serial port to send and receive data through TXD/RXD pins.
Real-World Scenario – Reliable Local Control
For example, when building a smart home controller for areas with unstable Wi-Fi, the HC-06 lets you control lights and appliances directly from your phone using Bluetooth. This avoids cloud dependency and reduces latency, giving instant and dependable control.
