HC-06 Bluetooth Serial Transceiver Module for Arduino

The HC-06 Bluetooth module is intended for use with two microcontrollers or systems to establish short-range wireless data communication. Its operation becomes transparent to the user after it is associated with a master Bluetooth device, such as a PC or smartphone. All data received through the serial input is sent over the air right away.

The Bluetooth module HC-06 has 4 pins, 2 for power and 2 to establish connection.

• VCC power supply. Typically hooked up to 5V pin of the Arduino.
• GND ground. Typically hooked up to GND pin of the Arduino
• RX reception pin. Typically hooked up to transmission pin (TX) of the Arduino
• TX transmission pin. Typically hooked up to reception pin (RX) of the Arduino
