1- Upload the Sketch to Arduino Board.   void setup() {   Serial.begin(9600);   delay(5000);   Serial.print("AT+NAME ScoreBoard ");# Enter the New Name on the Highlighted area.   delay(5000);   Serial.print("AT+PIN 4321 "); # Enter the New Pin on teh Highlighted area.   delay(5000); } void loop() { } 2-After Upload the Sketch ,Connect the Arduino Board and Bluetooth Module as per the wiring Diagram. 3- Power up the Bluetooth Module and Search the Bluetooth with the help of a smartphone. 4- Select the new name from the  available Bluetooth Devise list and pair it. 5-Enter the New PIN to connect it.
