Blutooth modual control Arduino Connected Device   First step you can open Arduino IDE type everything programming to  under the page first of all we will not everything for this programming now start (int) integer led1, led2 this 2 are variable. Let's discuss about hardware 1) blutooth modual 2) Arduino any.  Arduino to blutooth modual connection Arduino 5Volt connect to blutooth modual VCC, Arduino GND (Ground) to modual GND (Ground), Arduino TX pin connect to Modual RX pin and Arduino RX pin connect to Modual to TX pin. Arduino pin D2 connect LED Anode pin and another pin of LED Chotod connect to Arduino GND pin. Arduino pin D3 connect LED Anode pin and another pin of LED Chotod connect to Arduino GND pin.
