#include <SoftwareSerial.h>// import the serial library
 
SoftwareSerial puniBT(10, 11); // RX, TX
int ledpin=13; // led on D13 will show blink on / off
int BluetoothData; // the data given from Computer
 
void setup() {
  // put your setup code here, to run once:
  puniBT.begin(9600);
  puniBT.println("Bluetooth On please press 1 or 0 blink LED ..");
  pinMode(ledpin,OUTPUT);
}
 
void loop() {
  // put your main code here, to run repeatedly:
   if (puniBT.available()){
BluetoothData=puniBT.read();
   if(BluetoothData=='1'){   // if number 1 pressed ....
   digitalWrite(ledpin,1);
   puniBT.println("LED  On D13 ON ! ");
   }
  if (BluetoothData=='0'){// if number 0 pressed ....
  digitalWrite(ledpin,0);
   puniBT.println("LED  On D13 Off ! ");

}

Did you check for a header file that includes the function(s) that end with BT?
Maybe because of that,your system is not working...
And can you explain what does the program do from line(s) 16 to 24?
