2.Programing :

I used the following code for programing

include <SoftwareSerial.h>

SoftwareSerial mySerial(0, 2); // RX, TX

void setup() {

  mySerial.begin(9600);

  pinMode(3,OUTPUT);

  digitalWrite(3,LOW);

}

void loop() { // run over and over

  if (mySerial.available()) {

    char a=mySerial.read();

    if(a=='1'){

      digitalWrite(3,HIGH);

    }else if(a=='0'){

      digitalWrite(3,LOW);

    }

  }

}

3.Application Development :

This is the first time that I have ever try to create a mobile application I used the online MIT App Inventor 2 to creat my application as shown below.

Designing the App layout  

After completed the app layout I moved to block option  to setup  the app functions.
