How to use Arduino?

1. Arduino Script

*
 * Zalan's first Program
 */

 int ledPin = 13;
 void setup()
 { 
  //initialize pins as outputs
  pinMode(ledPin, OUTPUT);
 }
void loop()
{ 
  digitalWrite(ledPin, HIGH);
  delay(1000);
  digitalWrite(ledPin, LOW);
  delay(1000);
}

2. Arduino Script

int LED = 12;
int BUTTON = 4;


void setup()
{
  pinMode(LED,OUTPUT);
  pinMode(BUTTON,INPUT);
}

void loop()
{
  if(digitalRead(BUTTON) == HIGH)
  {
  digitalWrite(LED,HIGH);
  }else
  {
  digitalWrite(LED,LOW);
  }
}

3. Arduino Script

int switchPin = 8;
int ledPin = 13;
boolean lastButton = LOW;
boolean currentButton = LOW;
boolean ledOn = false;

void setup()
{
  pinMode(switchPin, INPUT);
  pinMode(ledPin, OUTPUT);
 
}

boolean debounce(boolean last)
{
  boolean current = digitalRead(switchPin);
  if (last != current)
  {
    delay(5);
    current = digitalRead(switchPin);
   
  }
  return current;
  
}
void loop()
{
  currentButton = debounce(lastButton);
  if (lastButton == LOW && currentButton == HIGH)
  {
    ledOn -= !ledOn;
  }
      lastButton = currentButton;
    digitalWrite(ledPin, ledOn);
  

}
