DESCRIPTION
+5V Function Connect to +5V Ground Connect to Ground UART_TXD, Bluetooth serial signal sending PIN Connect with the MCU’s (Microcontroller and etc) RXD PIN. UART_RXD, Bluetooth serial signal receiving PIN Connect with the MCU’s (Microcontroller and etc) TXD PIN. Mode switch input If it is input low level or connect to the air, the module is at paired or communication mode. If it’s input high level, the module will enter to AT mode. 4|Page 3. Sample Hardware Installation and Sample Source Code Below is the example of interfacing between Arduino UNO and PC via HC-05 Bluetooth Module. In this example, the communication mode is used. *Note: For AT mode (use to change the default setting or etc), please refer to this link Modify Diagram below shows the hardware connection between HC-05 Bluetooth Module and Arduino UNO. Besides Arduino, it may interface with any microcontroller such as PIC and etc.● VCC Arduino 5V
● GND Arduino GND
● TXD Arduino Pin RX
● RXD Arduino Pin TX
● KEY Connect to the air for communication mode 10k 5|Page Next, please get the sample source code and burn it into Arduino UNO.
