Arduino Remote Light

Program Def: Create program glow light using wireless media .
 Reuredment:
 two CKT two Arduino
                      one connected LED
                      another Connected Button
                     Each Arduino Connecrted Bluetooth HC-05 SETUP

One as Master Another As Slave :

#include <SoftwareSerial.h>

void setup()

}

Salve :
Write TTL Command
 AT+RMAAD (clear any paired devices)
AT+ROLE=0 (set as slave)
 AT+ADDR (Return H/w address remember it)
AT+UART=38400,0,0 (To fix the baud rate at 38400)


Master :
AT+RMAAD
AT+ROLE=1 (set it as master)
AT+CMODE=0 (To connect the module to the specified Bluetooth address and this Bluetooth address can be specified by the binding command)
 AT+BIND=xxxx,xx,xxxxxx ( XXXXXXXXXXXX Contain slave address)
 AT+UART=38400,0,0 (To fix the baud rate at 38400)
