Code

// Basic Bluetooth sketch
// Sends "Bluetooth Test" to the serial monitor and the software serial once every second.
//
// Connect the HC-05 module and data over Bluetooth
//
// The HC-05 defaults to commincation mode when first powered on.
// The default baud rate for communication is 9600
 
#include <SoftwareSerial.h>
SoftwareSerial BTserial(2, 3); // RX | TX
// Connect the BlueTooth TX to Arduino pin 2 RX. 
// Connect the BlueTooth RX to Arduino pin 3 TX through a voltage divider.
// 
 
char c = ' ';
 
void setup() 
{
    Serial.begin(9600);
    Serial.println("Enter AT commands:");
 
    // HC-05 default serial speed for communcation mode is 9600
    BTserial.begin(9600);  
}
