Hc05 Bluetooth module X1:-
LED X1:-
Male to female jumper wires:-

Let’s Start Building

The circuit is so simple and small, there are only a few connections to be made

Arduino Pins           Bluetooth Pins

RX (Pin 0)          TX

TX (Pin 1)            RX

5V                      VCC

GND                  GND

Connect a LED negative to GND of Arduino and positive to pin 13 . And you're done with the circuit

Note: Don’t  Connect RX to RX and TX to TX of Bluetooth to Arduino you will receive no data, Here TX means Transmit and RX means Receive

How Does it Work?

HC 05/06 works on serial communication.here the android app is designed sending serial data to the Bluetooth module when certain button is pressed. The Bluetooth module at other end receives the data and send to ardunio through the TX pin of Bluetooth module(RX pin of Arduino). The Code fed to Arduino checks the received data and compares.If received data is 1 the LED turns on turns OFF when received data is 0
