Push Button....

Connect all the components as this circuit.

If you connected these all components, you can open the Arduino IDE Software and write code.

The code is below,

...........................................................//Start of the code//.........................................................

int buttonstate = 2;  //Varialble buttonstate to 2

void setup() {

  pinMode(13,OUTPUT);

  pinMode(2,INPUT);

}

void loop() {

  buttonstate = digitalRead(2);  //Read the digitalpin - 2

  if(buttonstate == HIGH)     //If buttonstate high,

    digitalWrite(13,HIGH);  //Give high voltage to LED

  else                      //else,

    digitalWrite(13,LOW);  //Give low voltage to LED

} 

...........................................................//End of the code//.........................................................
