Bluetooth Arduino Connector
Connect your Bluetooth module to Arduino as shown in the image below. Be sure to connect the Reset pin of the Arduino programmer chip, which is located on the ICSP connector, to GND. Otherwise, the serial signals of the programmer chip will interfere with the signals of your Bluetooth module, and, as a result, the Arduino won't be programmed.

The aim of this circuit is to connect the Bluetooth Module with Arduino, Pair the Bluetooth Module with an Android Phone, send data from Android Phone to the Bluetooth Module using a simple App, read the data from Bluetooth Module through Arduino and finally, display the data and control a device based on the data.
Pretty straightforward, connect the bluetooth module to the arduino like so. RX-pin2. TX-pin 3. GND-GND. VCC-5v. Step 2 Plug in the Arduino and Upload the Sketch. Download the ino file and upload it to the arduino. Attachments. Bluetooth_Serial_Test.ino. Download. Step 3 Connect to the Bluetooth on Your Phone.
TX to RX Connect the TX pin of the module to the RX pin of Arduino. RX to TX Connect the RX pin of the module to the TX pin of Arduino. Use Voltage Dividers if necessary If your Bluetooth module works on 3.3V logic and your Arduino uses 5V, use a voltage divider on the RX pin to prevent damage. Step 3 Configuring the Bluetooth Module
Below you can find examples showing how to send data between two Arduino boards and how to connect to your Arduino board, reading and writing values using your smartphone. Remote LED Control. This example can be used with two Bluetooth LE supported Arduino boards, one with a button, and the other with an LED.
How to Add Bluetooth to an Arduino. Bluetooth can be added to any Arduino using either a shield or by connecting a Bluetooth transceiver with a serial connection. It typically costs between 10 and 20 to add Bluetooth to an Arduino depending on if a shield is used more expensive or if a serial connection is used cheaper.
About Bluetooth Serial Monitor App. The Bluetooth Serial Monitor App is a mobile app that has the User Interface that looks like the Serial Monitor of Arduino IDE. It communicates with Arduino via Bluetooth. You can interact with Arduino via this app as if Serial Monitor on your PC, without adding any special code for the Bluetooth module in your Arduino code, by doing the following step
Connect the HC-05 module to a device capable of sending and receiving serial data, like an Arduino or any microcontroller with UART. On the Bluetooth side, we establish a wireless connection between the HC-05 module and another Bluetooth-enabled device, such as an Android phone.
Arduino Bluetooth Options. While a handful of Arduino boards have Bluetooth built-in, some projects may require the use of external Bluetooth modules. We are going to connect an Arduino UNO to the nRF8001 module and send and receive data tofrom it as though it were a serial port. In other words, we will use the built-in ability to act as a
