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);      } }

blink a LED

 const int LED =13;                                //It takes LED as integer and fixed it's value to 13(non-changable). void setup()                                           // Main setup of program is written here  {   pinMode(LED,OUTPUT);                //It simply set pin 13 as output for LED. } void loop()                                    // It simply repeat/run the program over and over until power is removed. {   digitalWrite(LED,HIGH);         //It simply set voltage at pin 13 to 5v means ON state.   delay(1000);                            ...
