Terminal Blocks - Wire to Board TERM BLOCK 6POS 45DEG 3.7MM PCB
HC-06 is a Bluetooth module designed for establishing short-range wireless data communication between two microcontrollers or systems. This article mainly covers pinout, datasheet, specifications, applications, Arduino connection, and other details about HC-06 Bluetooth Module.
HC06B0500000G
The HC-06 is a class 2 slave Bluetooth module designed for transparent wireless serial communication. Its operation becomes transparent to the user once it is associated with a master Bluetooth device such as a PC, smartphone, or tablet. All data received through the serial input is sent over the air right away. When the module receives wireless data, it sends it out over the serial interface in the same format as it was received. In the user microcontroller program, no user code related to the Bluetooth module is required.

HC-06 is the best option when short-distance wireless communication is needed. The module is used for wireless communications of less than 100 meters.
The module is very easy to interface with and communicate with.
The module is one of the cheapest solutions for wireless communication of all types present in the market.
The module consumes very little power to function and can be used on battery-operated mobile systems.
The module can be interfaced with almost all controllers or processors as it uses a UART interface.

The HC-06 module has four pins, all of which must be connected to the Arduino UNO to work. The VCC pin receives the module's input voltage and is thus connected to the Arduino's 5V pin. The ground pin of the module is GND, which connects to the Arduino's ground pin. In other words, it serves as a baseline against which all other voltages are assessed. The RXD and TXD pins on the module are the receive and transfer pins, respectively. The RXD pin of the module receives serial data from the master device (smartphone) and then passes it to the TXD pin of the Arduino. The RX pin on the module is directly connected to the TXD pin on the module. The TXD pin on the module is connected directly to the RX pin on the Arduino whereas the RXD pin of the module is connected to the TX pin on the Arduino using a voltage divider circuit as the RXD on the module can only support voltage up to 3.3V.
The UART interface is used to communicate with the HC-06 module. This interface is used to send data to or receive data from the module. As a result, the module can be connected to any microcontroller or directly to a PC with an RS232 port (UART interface). The module's usual interface circuit to an Arduino is shown below.
HC-06 Circuit
As indicated in the diagram, the module is linked to a +5V regulated power source and a UART interface is established. Simply link the Arduino's RXD to the module's TXD, and the Arduino's TXD to the module's RXD through a resistor voltage divider. This voltage divider is used to convert Arduino's 5V logic signals to +3.3V logic signals that are compatible with the module. If separate power sources are used, the Arduino and module's ground must be linked for voltage reference.
After you've connected the module, you'll need to build a program in the Arduino IDE to receive and send data to it.
