TURN ON LED WHEN BUTTON IS PRESSED & KEEP IT ON AFTER BUTTON IS RELEASED & TURN OFF BY PRESSING BUTTON .


const int led=13;

const int led1=12;

const int button=7;

int a,b,c;


void setup()


{

pinMode(led,OUTPUT);

  pinMode(led1,OUTPUT);

  pinMode(button,INPUT);

}


  void loop()

{ 

 a=digitalRead(button);

 if((a==HIGH)&&(c==LOW))

   {

     b=1-b;

   }

c=a;

if(b==1)

    {

     digitalWrite(led,HIGH);

     digitalWrite(led1,HIGH);

    }

    else

    {


     digitalWrite(led,LOW);

     digitalWrite(led1,LOW); 


    }

}
